1 Agilent N8480 Series Thermocouple Power Sensors Data Sheet The N8480 Series thermocouple power sensors are amongst Agilent s most accurate and reliable sensors. These will eventually replace the 8480 Series thermocouple range only better with EEPROM and extended frequency and power ranges. Features High accuracy with excellent linearity and noise specifications Wide dynamic range in a single sensor Autodownload of calibration factor and corrections from EEPROM Option CFT of the sensors are available for full codecompatibility with the 8480 Series Broad compatibility with existing power meters: PSeries (N9A/2A), EPMP Series (E446A/7A) and EPM Series (N93A/4A, E448B/9B) Accurate, repeatable measurements Here s how: Excellent linearity (% approx.) and noise specifications. The sensors low further enhances accuracy by minimizing mismatch uncertainty. As if this weren t enough, these sensors also come with dualrange power for greater sensitivity to fluctuating signals, in particular. With high accuracy and stability, the N8480 helps you test confidently, faster. Calibrationeasy testing During test, calibrating your sensor is an essential step, yet it shouldn t be taking too much of your time and effort. With the N8480 sensors, there s no need for cumbersome keyingin of calibration factor (CF), nor concern for manual input errors. That s because CF, linearity and temperature corrections are all stored in the sensors EEPROM autodownloaded on calibration. Efficient calibration procedure makes for efficient testing overall, with N8480. One sensor, WIDEST range Pick an N8480 sensor any one and you ll see how its wide dynamic range equip you for various applications: metrology labs, radar, mobile radio, TDMA, GSM, WCDMA and WiMAX TM, among others. With up to 55 dbm wide dynamic range, the N8480 Series offers you the widest thermocouple sensor power range in the industry. System integration can be a pain, but not with the N8480 The N8480 Series sensors are backward compatible with Agilent s leading range of power meters, including the PSeries, EPM P Series and EPM Series. All that s needed is a simple firmware upgrade that s downloadable from the website, for free. Codewise, 00% of SCPI codes used on the ESeries sensors are reusable on the N8480, and this includes most of the ones used on the 8480 Series. For code migration from the 8480 Series, CFT options of the N8480 sensors and these will behave much like the 8480 Series sensors they replace.

2 Specification definitions There are two types of product specifications: Warranted specifications Characteristic specifications Warranted specifications Warranted specifications are covered by the product warranty and apply over 0 C to 55 C, unless otherwise noted. Warranted specifications include Measurement Uncertainty calculated with 95% confidence. Characteristic specifications Characteristic specifications are not warranted. They describe product performance that is useful in the application of the power sensors by giving typical, but non warranted performance parameters. These characteristics are shown in italics or denoted as typical, nominal or approximate. Characteristic information is representative of the product. In many cases, it may also be supplemental to a warranted specification. Characteristic specifications are not verified on all power sensors. The types of characteristic specifications can be placed in two groups: The first group of characteristic types describes 'attributes' common to all products of a given model or option. Examples of characteristics that describe 'attributes' are product weight, and 50 W input Type N connector. In these examples product weight is an approximate value and a 50 W input is nominal. These two terms are most widely used when describing a product's 'attributes'. The second group of characteristic types describes 'statistically' the aggregate performance of the population of products. These characteristics describe the expected behavior of the population of products. They do not guarantee the performance of any individual product. No measurement uncertainty value is accounted for in the specification. These specifications are referred to as typical. Conditions The power meter and sensor meet its specifications when: Stored for a minimum of two hours at a stable temperature within the operating temperature range, and turned on for at least 30 minutes. The power meter and power sensor are within their recommended calibration periods. Used in accordance to the information provided in the power meter s user's guide. 2

The table below provides the measurement noise for a particular sensor with the number of averages set at 6 (for normal mode) and 32 (for x2 mode). Use the noise multiplier, for the appropriate mode (normal or x2) and number of averages, to determine the total measurement noise value. Example: N848A power sensor, normal mode, number of averages = 4 Measurement noise calculation: <80 nw x 2.75 = <220 nw No. of averages Noise multiplier Normal mode x2 mode RH is the abbreviation for relative humidity. 2. Within one hour after zero set, at a constant temperature, after a 24hour warmup of the power meter with sensor connected. 3. The number of averages at 6 for Normal mode and 32 for x2 mode, at a constant temperature, measured over a oneminute interval and two standard deviations. 8

9 Switching point The N8480 Series power sensors (standard only, ie. excluding Option CFT) have two measurement ranges: a lower power range and upper power range. The power meter automatically selects the proper power level range. To avoid unnecessary switching when the power level is near the switch point, switching point hysteresis has been added. N848A/82A/85A/87A and /AR power sensors This hysteresis causes the lower power range to remain selected until approximately 0.5 dbm as the power level is increased. Above this power, the upper power range is selected. Likewise, the upper power range remains selected until approximately.5 dbm as the signal level decreases. Below this power, the lower power range is selected. N848/2B power sensors This hysteresis causes the lower power range to remain selected until approximately 29.5 dbm as the power level is increased. Above this power, the upper power range is selected. Likewise, the upper power range remains selected until approximately 28.5 dbm as the signal level decreases. Below this power, the lower power range is selected. N848/2H power sensors This hysteresis causes the lower power range to remain selected until approximately 7.5 dbm as the power level is increased. Above this power, the upper power range is selected. Likewise, the upper power range remains selected until approximately 6.5 dbm as the signal level decreases. Below this power, the lower power range is selected.

Settling time: 0 to 99% settled readings over the GPIB Calibration factor and reflection coefficient Calibration factor (CF) and reflection coefficient (Rho) data is unique to each sensor. The CF corrects for the frequency response of the sensor. The Agilent EPM Series, EPMP Series and PSeries power meters automatically read the CF data stored in the sensor s EEPROM and use it to make the corrections. Reflection coefficient (Rho or ) relates to the according to the following formula: = + Typical measurement uncertainties of the calibration factor (CF) are listed in the following table. There is only one set of CF data used for both high and low range of each sensor. The typical measurement uncertainty data listed in the table is meant to help users on the measurement uncertainty estimation. These values are only a guideline and are not to be used in any accurate uncertainty calculations.
