Verifying Performance

Understanding the Tests

Equipment Required

HP/Agilent 8566B Spectrum Analyzer

Theory of the Test

The UUT is set to generate a CW signal at various levels and frequencies. The HP/ Agilent 8566B is used to measure the signal level and then the level of the harmonics or spurious signals.

Things To Check In Case Of Problems

•The instruments should have their timebases locked together to assure that the frequency offsets for the spurious measurements are accurate.

Test 03: Signal Pulse Equipment Required (excluding Agilent 8922M/S)

Modulation

HP/Agilent 8116APulse Generator

Theory of the Test

The HP/Agilent 8116A pulse generator drives the pulse input of the UUT and causes it to generate pulsed RF signals. These signals are detected with the negative diode detector and analyzed with the oscilloscope. The UUT is set to generate two different on/off ratios: 30 dB and 80 to 90 dB. Rise time and fall time for each of these is measured.

When the Agilent 8922S is the UUT, the RF Generator is set to generate a pulsed GMSK signal. This signal is then analyzed with the UUT detector and oscilloscope.

Things To Check In Case Of Problems

•The oscilloscope is used to automatically measure rise and fall times. If the RF signal has high video feedthrough, it may cause the oscilloscope to make a faulty reading by triggering on the video feedthrough instead of the actual pulse.

•A diode detector with a greatly different sensitivity may cause the demodulated waveform to overrange on the oscilloscope or have reduced accuracy because of the resolution of the oscilloscope.
