Activate Test Program and select power level and channel number. Enable B/S and S/H so both are in normaloperating condition. B. Test setup for BER Test and Jamming Margin Test1. Disconnected antenna connection points for B/S and H/S. 2. Connected B/S and H/S as diagram shown above. 3. Activate Test program ( FCCV3_2.exe) and select Transmit-only Test. Disconnected Signal Generator from point“A” of diagram as shown above. Connected Spectrum analyzer to point “A”. Activate program and recordMaximum reading and record as “S”. 4. Disconnected Spectrum analyzer from Point “A” and reconnect back to Signal Generator. 5. “Park” B/S and H/S for one minute and activate test program provided by Rockwell for BER test mode. 6. Press “Start S1-S2 BS Master” starts the tests. 7. Set Signal generator in accordance to FCC requirement with 5kHz step(up to 960KHz away in Rl’s DCT), at thesame time record level ( Jamming level (J))with Bit Error Rate=10e-3 8. Stop BER, increase 5kHz and repeat step 5.
