28 3 Using the Automated Test Application Oscilloscope Channel Automated Setup Signal Amplitude Time Range (in debug mode only) Sampling Rate (in debug mode only) Trigger Type Trigger Level (in debug mode only) Trigger Sensitivity Select the oscilloscope channel used to capture the waveform. Select "Fully Automated" if you wish the software to automatically set up the oscilloscope and capture the data packets. The horizontal and vertical scale and trigger level are determined based on the time range and signal amplitude provided. The horizontal, vertical scale, and trigger level are determined based on the time range and signal amplitude provided. Select "Manual" if you wish the set up the oscilloscope manually to capture the data packets. Once the oscilloscope has been set up, the software will digitize and save the waveform. Select or enter the estimated amplitude of the signal to capture. This is used to set the vertical scale of the oscilloscope. In Compliance mode, the default time range is set to 150 us to capture at least two packets of 96 symbols payload. However, in Debug mode, you can select or enter the time range used when capturing the waveform. This is for cases where the device transmits payload lengths other than 96 symbols. In Compliance mode, the sampling rate is set to 20 Gsa/s for band groups 1 and 2 and 40 Gsa/s for band groups 3 and above. However, in Debug mode you can select the sampling rate to use. Select the trigger condition to use: Select "Zone Qualify trigger" to use the Zone Qualify in Infiniiscan to capture a data packet of at least 96 symbols length. Select "Edge trigger" to use a simple edge triggering to capture packets of any length. Select "Auto sweep" to change trigger sweep to "Auto" to trigger on anything. This is for band groups > 4 (above 7 GHz). NOTE: For Band Groups 3 and above, the trigger will automatically be set to "Auto sweep". This is because the oscilloscope trigger does not work above 7 GHz. In Compliance mode, the trigger level is automatically determined based on the measured input signal. However, in Debug mode you can manually set the trigger level in case the automatically determined trigger level is incorrect. Select the trigger sensitivity. NOTE: For Band Groups 3 and above, the trigger sensitivity is automatically set to "High". 28 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help

Therefore, the tests have been structured as radiated tests and Loop Back Mode is utilized as a way to cycle the DUT through various TFC's and Data Rates. 30 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help

31 Using the Automated Test Application 3 Figure 1 Loop Back Mode Testing Overview 1 Connect an antenna directly to the input of a UWB amplifier. Connect the output of the amplifier to the oscilloscope via a high bandwidth SMA cable. In some cases, an adapter might be necessary at the oscilloscope front end. 2 Mount the receiving antenna in the test probe holder (to keep its position fixed) and adjust to be orthogonal to the test bench. The DUT antenna also should be positioned orthogonal to the test bench. Place the receiving antenna approximately 5 cm (~2 in) from the DUT antenna. 3 Ensure adequate distance is placed between the associating device's antenna and the DUT. This gives the ability to distinguish DUT signals from those of the associating device. Approximately 1m is sufficient, but the antennas may need to be moved closer for higher data rates.

81 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help A Capturing a Required Waveform Below are the steps to set up the DUT and the oscilloscope to capture the required waveform: 1 Configure the DUT so that it is in loop back mode or continuously transmitting data packets. Set the loop back data rate and packet size to achieve 96 symbol payload size. Example: 53.3 Mbps, packet size, 195 bytes = 96 symbol payload size 200 Mbps, packet size, 745 bytes = 96 symbol payload size 480 Mbps, packet size, 1795 bytes = 96 symbol payload size 2 Select the data rate and size of payload. 3 Connect an antenna to the oscilloscope via a flexible SMA cable, positioned close to the DUT. 4 The test begins by setting the horizontal/vertical ranges of the oscilloscope. The oscilloscope is autoscaled to find the best vertical scale. The software then queries the new vertical scale. If the vertical scale remains at 1V, this means the autoscale failed to find any signal. The vertical scale will then be set using the signal amplitude settings in the Configure tab. If a valid vertical scale is found (<1V), the oscilloscope's horizontal scale will be set to 150 us before re- measuring the signal amplitude. A larger horizontal scale is set to ensure at least one packet is visible when measuring the signal amplitude. The new vertical scale is determined as follows: i Take 10 readings of VPP and burst width and average them. Burst width measurement will ensure signal being measured is not noise but valid packets. If either VPP or burst width are less than 9999 (which means valid values) then set the vertical scale to: A 81

82 A Capturing a Required Waveform ii Vertical scale = VPP / 7 If either VPP or burst width is more than 9999 (invalid value) increase the vertical scale by double as the signal could be clipped of (which happens if the oscilloscope autoscaled on noise). iii (a) and (b) will be repeated up to two times if failed to set the vertical scale. NOTE The data is demodulated and analyzed in intervals of 96 symbols. To capture a packet containing 96 symbols a time range of at least 50 us is required. 1 Packet = 30 Preamble symbols + 12 header symbols + Payload For a 96 symbols payload, 1 Packet = = 138 symbols Since each symbol is ns long, time range of a packet with payload size of 96 symbols Time range = 138 x ns = 43 us 5 There are three trigger modes: Zone Qualify, Edge, or Auto: To perform WiMedia tests you want to test a data packet (or loopback packet) NOT a beacon packet. Zone Quality triggering is turned on to differentiate a beacon from a data packet. Edge trigger mode performs a simple edge triggering. Auto mode is mostly used for Band Groups 4 and above since the oscilloscope's trigger does not work above 7 GHz. 6 Zone qualify trigger mode: Set the trigger to trigger on a rising edge. In Compliance mode, the trigger level is calculated based on the vertical scale set earlier: Trigger level = vertical scale In Debug mode, the trigger level is set based on your selection for Trigger Level in the Configure Tab. Based on the calculations above, a packet containing 96 symbols or more has a width of at least 43 us. A beacon packet is typically around 20 us. Two zones are created, the width, height, and center coordinates are determined as follows: Zone 1 (must not intersect): Width = 5 us Height = vertical scale * 2 Zone1 Center X-coordinate = -3.5us from trigger Zone1 Center Y-coordinate = vertical scale * 3 Zone 2 (must intersect): Width = 10us Height = vertical scale * 2 82 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help

83 Capturing a Required Waveform A Zone2 Center X-coordinate = 40 us from trigger Zone2 Center Y-coordinate = vertical scale * 2 If a data packet is present, the data packet would intersect with this zone and trigger the oscilloscope. Figure 26 Beacon packet is only 20 us. Should not intersect the zone Agilent U7239A WiMedia Wrapper Automated Test Application Online Help 83

84 A Capturing a Required Waveform Figure 27 Data packet is long enough to intersect the zone 7 Edge trigger mode: In Compliance mode, the trigger level is calculated based on the vertical scale set earlier: Trigger level = vertical scale * 1 In Debug mode, the trigger level is set based on your selection for Trigger Level in the Configure Tab. 8 Auto trigger mode: Trigger sweep is set to auto to capture anything. However, to make sure that there is at least one full packet is present, a mask test is used. The oscilloscope will stop acquiring data once the mask is violated. 84 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help

86 A Capturing a Required Waveform Figure 29 Mask violated when a full packet is present NOTE For Band groups 3 and above, the trigger is set to "Auto" with "high" sensitivity because trigger functions only work on signals up to 7 GHz. 9 Sampling rate = 20 Gsa/s for band groups 1-2 and 40 Gsa/s for band groups Memory depth is set using the Time Range value you provide: Memory depth = Time Range * Sample rate 11 Once the oscilloscope detects a trigger, the software proceeds to detect the band group of the signal. WiMedia signals are divided into 6 band groups from 3.16 GHz to GHz band range. Each band has a bandwidth of ~1.6 GHz with the exception of band group 6 which has a bandwidth of 1.1 GHz. Here's how the band group is detected: 86 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help

87 Capturing a Required Waveform A Math function FFT Magnitude is turned on on FUNC1 with the following setting: Horizontal range: 11 GHz, Center Freq: 6.5 GHz. Vertical range: 160 dbm, Offset - 50 dbm. The maximum amplitude of the FFT is measured. Horizontal markers will be placed around the frequency range of band group 1. The vertical markers will be placed at: Y1Pos = Maximum amplitude of the FFT. Y2Pos = Y1Pos 13 dbm. Figure 30 Horizontal and vertical placements if the histogram markers Agilent U7239A WiMedia Wrapper Automated Test Application Online Help 87

88 A Capturing a Required Waveform If the number of histogram hits > 5000 then the software concludes that the packet spectrum falls in this band group. Else the horizontal markers will be moved to the next band group range and the number of hits will be evaluated again. This will go on until either a valid band group is detected or else the software will throw an exception.

For WiMedia tests the number of acquisitions taken depends on the number of averages set in the Configure tab. The software performs 15 retries and if no signal is detected, an error message appears. If the error message appears, you can abort the test by clicking Cancel, or you can manually set up the oscilloscope to capture a packet and then click OK. After you click OK, the application gets the waveform and performs the band group detecting steps described earlier. Figure 33 Error message 13 The waveform is captured and saved. The format in which the waveform is saved depends on whether WiMedia tests or Wireless USB tests is selected. WiMedia tests: The waveform is saved into a MATLAB format *.mat file so that the waveform can be processed and analyzed by the VSA application. Before the waveform is saved as a *.mat format, the waveform must first be down converted using MATLAB. The down- converted file is saved into location: C:\Documents and Settings\All Users\Application Data\Agilent\ Infiniium\Apps\WiMediaWrapperTest\Project\Filename: Input_tfc@x_bps@x_iteration.mat For example: Input_tfc1_bps480_bg1_1.mat Depending on the Number of Averages set in the Configure tab, one waveform file is saved for each iteration.

90 A Capturing a Required Waveform The waveform is saved as *.bin format so that the Intel EVM Tool can process the waveform. Since the EVM tool cannot automatically detect the TFC and data rate of the signal, this information must be provided through the file name. Hence, files are named using the following convention: Devicename_tfc@x_bps@datarate_gss@samplerate.bin For example, a device "phy1" with TFC1, data rate 480 Mbps, captured at a sample rate of 20 Gsa/s should be named: Phy1_tfc1_bps480_gss20.bin The TFC and data rate information is obtained from the settings in the Configure tab. Selecting the wrong TFC and data rate may cause inaccurate analysis. The waveform is saved into location: C:\Documents and Settings\All Users\Application Data\Agilent\ Infiniium\Apps\WiMediaWrapperTest\Project\ Devicename_tfc@x_bps@datarate_gss@samplerate.bin 90 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help

91 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help B Loading a Pre-recorded Waveform Below are the steps to load a pre- recorded waveform for testing: 1 Under Input Signal on the Setup tab select "Recorded signal". 2 Then, click on the Browse button to select the file to be tested. The supported formats are Waveform file (*.bin), Matlab (*.mat) and VSA proprietary format (*.sdf). NOTE The contents of the Matlab file must follow the format set by the VSA software. 3 If a waveform file (*.bin) is loaded, the data will be down converted and saved as a Matlab format so that VSA can process the file. VSA currently does not support *.bin format. A 91

93 Agilent U7239A WiMedia Wrapper Automated Test Application Online Help C VSA Analysis (for WiMedia Tests) Once a signal is available via live capture or pre- loaded waveform, tests proceed to launch the VSA software. The software checks for the following: Check that VSA version 8.00 and above is present, else exit the test completely. If the oscilloscope already has its own BHB option license, then use the license to launch the VSA application. The VSA GUI will be visible. If the oscilloscope does not have its own BHB option license, then load the embedded license (that comes with WiMedia app) and launch the VSA application. The VSA GUI will not be visible when using embedded license. VSA will be set to run in simulation mode. The waveform file saved earlier or the selected recorded file will be loaded. With the VSA running in simulation mode, other external devices are allowed to communicate with the oscilloscope as opposed to having the VSA poll data directly from the oscilloscope where the VSA will lock the oscilloscope from communicating with other devices. Before setting the VSA to run in simulation mode, the software will save the previous hardware settings. For example, you may have previously set the VSA to connect to a oscilloscope. The oscilloscope address will be saved before changing the VSA to run in simulation mode. The hardware settings will be restored upon exiting the WiMedia Wrapper application; that is, VSA will be reset to point to the oscilloscope address before terminating the VSA application. A 93
