Spectrum Analyzer SSB Phase Noise Verification

This test verifies the single sideband phase noise of the Spectrum Analyzer in Spectrum Master Models
MS2723B and MS2724B.
Procedure:
1. Connect the external 10 MHz Reference to the Anritsu MG3692x Synthesized Signal Generator, as
shown in Figure
2. Connect the output of the synthesized signal generator to the Spectrum Analyzer RF In connector of the
MS2723B or MS2724B.
3. Set the MG3692A output to 2.00 GHz CW, with an RF output level of +4 dBm.
4. Verify that the MS272xB is in the Spectrum Analyzer mode. Preset the instrument.
5. Press the Amplitude soft key, then set the Reference Level to 0 dBm.
6. Press the Atten Lvl soft key and enter 15 dB.
7. Press the Freq soft key and set the Center Frequency to 2000.05 MHz.
8. Press the Span soft key and set the span to 110 kHz.
9. Press the BW soft key and set the RBW to 1 kHz.
10. Press the VBW soft key and set the VBW to 3 Hz.
11. Press the Shift key and then press the Trace (5) key.
12. Press Trace A Operations, and set the # of Averages to 7.
13. Wait until the Trace Count (left side of display) displays 7/7.
14. If the Center Frequency was changed and delta marker is On, then press the Delta On/Off soft key to turn
Delta Off.
15. Press the Marker key and press the Peak Search soft key.
16. Press the Delta On/Off soft key to turn Delta On.
17. Use the keypad to enter 10, and press the kHz soft key.
18. Subtract 30 from the dB value that is shown on the marker readout in order to convert the value to
dBc/Hz (for example, if the marker reads –80 dB, then the value becomes –110 dBc/Hz). Record the
dBc/Hz value in
on page A-2.
19. Repeat Step 17 and Step
Record the dBc/Hz values in
20. Repeat Step 7 through Step
appropriate test parameters listed in
1.11 MHz for the Span, 1 kHz for RBW, 30 Hz for VBW and 1 MHz for the marker delta.
21. Repeat Step 3 through Step
output level of +5 dBm, and 12.0 GHz CW with an RF output level of +13 dBm, and also 19 GHz CW
with an RF output level of 0 dBm for the MS2724B only. Use the test parameters that are listed in the
respective test record tables for each frequency offset value.
Record the dBc/Hz values in
on page A-3, as required.
