Table 2. Level Accuracy Test Results

4.7. Displayed Average Noise Level
The following test can be used to verify the displayed
average noise level of the Spectrum Analyzer.
a. Equipment Required:
·Anritsu 28N50-2 or SM/PL 50 ohm Ter-
mination or equivalent
b. Procedure:
1. Connect the 50 ohm termination to the
Spectrum Analyzer RF Input.
2. On the Spectrum Analyzer, press and
hold the ESCAPE/CLEAR key, then press
the ON/OFF key to turn on the Spectrum
Analyzer. (This sets the instrument to
the factory preset state.)
NOTE
Before continuing, allow a 30-minute warm
up for the internal circuitry to stabilize.
3. On the Spectrum Analyzer, press the AM-
PLITUDE key and the REF LEVEL soft key.
4. Enter –75 and press the ENTER key to set
the Reference Level to –75 dBm.
5. Press the SCALE soft key and enter 5,
then press ENTER.
6. Press the BW/SWEEP key.
7. Press the DETECTION soft key, then press
the AVERAGE soft key, then select BACK.
8. Press the RBW soft key and then the EDIT
soft key. Use the Up/down arrow key to
select 10 kHz. Press ENTER to set the res-
olution bandwidth to 10 kHz and select
BACK.
9. Press the VBW soft key and then the EDIT
soft key. Use the Up/down arrow key to
select 100 Hz and press ENTER to set the
video bandwidth to 100 Hz.
10. Press the FREQ/SPAN key and the START
soft key.
11. Enter 100 and press the kHz soft key to
set the start frequency to 100 kHz.
12. Press the STOP soft key and enter 500,
then press the kHz soft key to set the stop
frequency to 500 kHz.
13. Wait until a full sweep is complete.
14. Press the MARKER key and then press
the M1 soft key.
15. Press the MARKER TO PEAK soft key. Re-
cord the M1 amplitude reading and ver-
ify it is £–80 dBm.
16. Press the FREQ/SPAN key and the START
soft key.
17. Enter 500 and press the kHz soft key to
set the start frequency to 500 kHz.
18. Press the STOP soft key and enter 4, then
press the MHz soft key to set the stop fre-
quency to 4 MHz.
19. Wait until a full sweep is complete.
20. Press the MARKER key and then press
the M1 soft key.
21. Press the MARKER TO PEAK soft key. Re-
cord the M1 amplitude reading and ver-
ify it is £–95 dBm.
22. Press the BW/SWEEP key.
23. Press the VBW soft key, and then the EDIT
soft key. Use the Up/down arrow key to
select 3 kHz, and press ENTER to set the
video bandwidth to 3 kHz.
24. Press the FREQ/SPAN key and the START
soft key.
25. Enter 4and press the MHz soft key to set
the start frequency to 4 MHz.
26. Press the STOP soft key and enter 1000,
then press the MHz soft key to set the
stop frequency to 1000 MHz.
27. Wait until a full sweep is complete.
28. Press the MARKER key and then press
the M1 soft key.
29. Press the MARKER TO PEAK soft key. Re-
cord the M1 amplitude reading and ver-
ify it is £–95 dBm.
30. Press the FREQ/SPAN key and the START
soft key.
31. Enter 1000 and press the MHz soft key to
set the start frequency to 1000 MHz.
32. Press the STOP soft key and enter 2000
and press the MHz soft key to set the stop
frequency to 2000 MHz.
33. Wait until a full sweep is complete.
