1 The SDR-play RSP1 is a powerful wideband full-featured SDR which coers all frequencies from 1 khz up to 2 GHz. All it needs is a PC and an antenna to proide excellent communications receier functionality. Combined with the power of readily aailable SDR receier software (including our own SDRuno ) you can enjoy all modes of operation while monitoring up to 1 MHz of spectrum at a time. An open API allows deelopers to create new demodulators or applications around the platform. RF Tuning Range Intermediate Frequencies The RF tuning range of the SDRplay module is detailed below. The SDR play module supports the modes of operation Continuous Coerage from 1KHz 2GHz Zero IF for all IF bandwidths Front End Filtering Low IF for bandwidths 1.536MHz The front end is protected by a series of passie RF filters. These filters are automatically selected based on the RF frequency programmed. The filter ranges are shown below IF Bandwidths The following IF filter bandwidths are supported 12 MHz Low Pass Filter 12 3 MHz Band Pass Filter 3 6 MHz Band Pass Filter 6 1MHz Band Pass Filter 1 25 MHz Band Pass Filter 25 MHz Band Pass Filter 1 MHz Band Pass Filter 1MHz High Pass Filter khz 3 khz 6 khz MHz 5.

The plots show the SINAD performance for different narrow band FM frequency deiations. In addition the SINAD Vs Input leel is also shown. These measurements are taken at range of different test frequencies, in each case a 1kHz audio tone was used to conduct the measurements 15MHz Test Results SINAD Vs Input 15MHz kHz Frequency Deiation 12.5kHz Frequency Deiation Input leel (dbm) SINAD Vs Frequency -115dBm, 15MHz Frequency Deiation (khz)

The plots show the input oltage requirement to achiee 12 db SINAD. The AM signal has a 1 KHz modulating tone with 3% AM and the FM signal has a 1 KHz audio tone with 3.5 KHz deiation 1.3 AM Sensitiity Vs Frequency V rms for 12 db SINAD, 1KHz Audio, 3% AM AM Sensitiity (uv for 12 db SINAD) NBFM Sensitiity Vs Frequency V rms for 12 db SINAD, 1KHz Audio, 3.5kHz Deiation FM Sensitiity (uv for 12dB SINAD)

7 , Noise Figure and IIP3 The tables below show the gain, noise figure and IIP3 data for the SDRplay module. The data is gien for each of the main front end gain states. The noise figure and gain data can be used to help calculate whether there is sufficient SNR in the receier when the tuner LNA is enabled within the AGC routine. Further information on programming the AGC can be found in the AGC reference note. The data has been split down to show the performance for each of the front end filter configurations.
