Performance Verification
Procedure:
1. Set the MG3692x Synthesized Signal Generator to 50.1 MHz CW, and set the output level to –30 dBm.
2. Connect the synthesized signal generator output to the Spectrum Analyzer RF In connector of the
MS2723B or MS2724B through the 50 MHz low-pass filter, as shown in
3. Set the MS2723B or MS2724B to Spectrum Analyzer mode and then preset the instrument.
4. Set the MS2723B or MS2724B as follows:
Center Frequency: 50.1 MHz
Span: 100 kHz
Reference Level: –20 dBm
Atten Lvl: 0 dB
RBW: 1 kHz
VBW: 10 Hz
Detection: Peak
5. Press the Shift key and then the Trace (5) key. Press Trace A Operations and set # of Averages to 5.
6. After the Trace Count displays "5/5" (left side of display), press the Marker soft key and press
Peak Search.
7. Record the amplitude of the 50.1 MHz signal in
Distortion" on page
8. Change the Center Frequency of the MS2723B or MS2724B to 100.2 MHz. Do not adjust the MG3692x
Synthesized Signal Generator.
9. After the Trace Count shows "5/5", press the Marker soft key and press Peak Search.
10. Record the amplitude of the signal at 100.2 MHz in
11. Convert the values of the 50.1 signal and the 100.2 signal to positive values and subtract the smaller
from the larger. Record the result into the "Second Harmonic Distortion" column in
that it is within specification.
