5. Set the AC voltmeter to measure AC Volts rms. The measured voltage should read 23.315 mV ± 0.5 mV.
Record the measured value in the VM1 table,
(23.315 mV ± 0.5 mV)" on page
6. While keeping the MG3692x output power unchanged, set the frequency to 95 kHz and record the
measured voltage into the "Measured VM2" column in
100 kHz Amplitude Accuracy Verification" on page
7. Convert the measured voltage to power in dBm by using the following formula:
P = (20Log
in 10
8. Enter the result in units of dBm into the characterization chart
record (Table A-45, "9 kHz to 100 kHz Amplitude Accuracy Verification" on page
9. Repeat Step 6 through Step
10. Remove the T3449 Test Fixture from Port 2.
