Performance Verification 2-10 Spectrum Analyzer Residual Spurious Response Verification
S312D MM PN: 10580-00195 Revision B 2-23
16. Record the M1 amplitude reading in Table A-13, “Spectrum Analyzer Residual Spurious Response
Verification” on page A-8 and verify that it is ≤ –80 dBm.
17. Press the
FREQ/DIST
key and the
Start
soft key.
18. Enter
10
and press the
MHz
soft key to set the start frequency to 10 MHz.
19. Press the
Stop
soft key and enter
1000
, then press the
MHz
soft key to set the stop frequency to
1000 MHz.
20. Wait until one full sweep is complete.
21. Press the
MARKER
key and record the M1 amplitude reading in Table A-13 and verify that it is
≤ – 90 dBm.
22. Press the
FREQ/DIST
key and the
Start
soft key.
23. Enter
1000
and press the
MHz
soft key to set the start frequency to 1000 MHz (1.0 GHz).
24. Press the
Stop
soft key and enter
1600
, then press the
MHz
soft key to set the stop frequency to
1600 MHz (1.6 GHz).
25. Wait until one full sweep is complete.
26. Press the
MARKER
key and turn on M1. Record the M1 reading in Table A-13 . Verify that it
is ≤ – 90 dBm.
Note
If a spur with an amplitude larger than –80 dBm occurs, then wait another full sweep and observe
whether the spur occurs at the same point on the second sweep. If the spur does not occur at the
same point on the second sweep, then the spur on the first sweep does not cause the test to fail.
Note
If a spur with an amplitude larger than –90 dBm occurs, wait another full sweep and observe
whether the spur occurs at the same point on the second sweep. If the spur does not occur at the
same point on the second sweep, then the spur on the first sweep does not cause the test to fail.
Note
If a spur with an amplitude larger than –90 dBm occurs, then wait another full sweep and observe
whether the spur occurs at the same point on the second sweep. If the spur does not occur at the
