TEST MODEL
RECORD 68297B/68397B
3-16 Pulse Modulation Test: RF On/Off Ratio
Test Procedure (1 GHz) Lower Limit Measured Value Upper Limit
Set F1 to 1.0 GHz
Measure and record the peak of the signal on the Spectrum
Analyzer. (Measured signal must be >60 dB below top graticule
to meet specification; this represents an On/Off Ratio of >80 dB.) .
60 dB _______ dB N/A
Test Procedure (5 GHz)
Set F1 to 5.0 GHz
Measure and record the peak of the signal on the Spectrum
Analyzer. (Measured signal must be >60 dB below top graticule
to meet specification; this represents an On/Off Ratio of >80 dB.) .
