4.4.3.4.4 Pulse Level Accuracy Test Procedure
1. Connect the output of the UUT to the 80350A series sensor and 8650A power meter.
2. Set the pulse generator using the settings described in step 2 of the Rise and Fall Time Test Proce-
dure.
3. Set the UUT using the settings described in step 3 of the Rise and Fall Time Test Procedure except
set the External PM state to Off.
4. Set the 8650A sensor mode for the 80350A sensor to CW.
5. Measure and record the CW levels for the specified frequency test points.
6. Toggle the External PM state to On.
7. Set the 8650A sensor mode for the 80350a sensor to Peak. Adjust the sample delay to 500 nsec.
8. Measure and record the Peak levels for the specified frequency test points.
9. Compare the CW levels to the peak levels.
4.4.3.4.5 On/Off Ratio Test Procedure
1. Connect the output of the UUT to the Spectrum Analyzer.
2. Repeat steps 1,2 and 4 of the Rise and Fall Time Test Procedure.
3. Set the UUT to the test frequency.
4. Set the Spectrum Analyzer frequency to the test frequency. Set the frequency span to 0 Hz and
adjust the sweep rate to display two pulses on the display (approximately 4 usec.). It may be nec-
essary to adjust the resolution bandwidth. Set the vertical scale to 10 dB/div. Adjust the reference
level so that the peak level of the pulse is at the top of the display.
5. Measure and record the difference between the On state of the UUT to the Off state of the UUT.
6. Repeat steps 3 through 5.
