3-2 PN: 10580-00307 Rev. D MS20xxC MM
9. Enter 0 and press the dB soft key to set Atten Lvl to 0 dB.
10. Ensure that the Pre Amp soft key is in the Off position. If the preamp is On, then press the Pre Amp soft
key to turn it Off.
11. Press the Detection soft key and ensure that Peak is selected.
12. Press the Freq hard key and then the Start Freq soft key.
13. Enter 9 and then press the kHz soft key to set Start Frequency to 9 kHz.
14. Press the Stop Freq soft key.
15. Enter 100 and then press the kHz soft key to set Stop Frequency to 100 kHz.
16. Press the BW hard key and then the RBW soft key.
17. Enter 300 and then press the Hz soft key to set RBW to 300 Hz.
18. Press the VBW soft key.
19. Enter 10 and then press the Hz soft key to set VBW to 10 Hz.
20. Wait until one sweep is completed.
21. Press the Marker hard key and then the Peak Search soft key.
22. Record the Marker 1 amplitude reading in Table A-8, “Spectrum Analyzer Residual Spurious Response
with Preamp Off” on page A-6 for MS2036C, in Table A-29, “Spectrum Analyzer Residual Spurious
Response with Preamp Off” on page A-16 for MS2037C or in Table A-53, “Spectrum Analyzer Residual
Spurious Response with Preamp Off” on page A-29 for MS2038C in Appendix A and verify that the
amplitude is within specification.
23. Repeat Step 12 through Step 22 for the other Start and Stop frequencies with the RBW and VBW settings
as listed in Table A-8
for MS2036C, in Table A-29 for MS2037C or in Table A-53 for MS2038C.
Residual Spurious Response with Preamp On
24. Press the Amplitude hard key and then the Reference Level soft key.
25. Enter –50 and press the dBm soft key to set Reference Level to –50 dBm.
26. Ensure that Atten Lvl is set to 0 dB.
27. Press the Pre Amp soft key to turn Pre Amp to On.
28. Press the Freq hard key and then the Start Freq soft key.
29. Enter 1 and then press the MHz soft key to set Start Frequency to 1 MHz.
30. Press the Stop Freq soft key.
31. Enter 30 and then press the MHz soft key to set Stop Frequency to 30 MHz.
32. Press the BW hard key and then the RBW soft key.
33. Enter 3 and then press the kHz soft key to set RBW to 3 kHz.
34. Press the VBW soft key.
35. Enter 300 and then press the Hz soft key to set VBW to 300 Hz.
36. Wait until one sweep is completed.
37. Press the Marker hard key and then the Peak Search soft key.
Note
If a spurious signal with amplitude exceeding specification occurs, then wait another full sweep and
observe whether the spurious signal occurs at the same point on the second sweep. If the spurious
signal does not occur at the same point on the second sweep, then the spurious signal on the first
sweep was not real.
