6. SPECTRUM ANALYZER PHASE NOISE

VERIFICATION

This test can be used to verify the phase noise of the

Site Master Spectrum Analyzer.

a. Equipment Required:

· Anritsu MG3692A Synthesized Signal

Source, with options 2A, 4 and 15A, or

equivalent

b. Procedure:

1. Connect the output of the source to the

Site Master RF Input.

2. Connect the external power supply

(Anritsu part number 40-115) to the Site

Master.

3. Press and hold the

ESCAPE/CLEAR key,

then press the

ON/OFF key to turn on the

Site Master. (This sets the instrument to

the factory preset state.)

NOTE

Before continuing, allow a 30-minute warm up

for the internal circuitry to stabilize.

4. Set the MG3692A output to 1000 MHz,

with an RF output level of –30 dBm.

5. On the Site Master, press and hold the

ESCAPE/CLEAR key, then press the

ON/OFF key to turn on the Site Master.

(This sets the instrument to the factory

preset state.)

6. Press the

SWEEP key.

7. Press the

RBW soft key and the MANUAL

soft key. Use the Up/down arrow key to

select 10 kHz. Press

ENTER to set the

resolution bandwidth to 10 kHz then

press the

BACK soft key.

8. Press the

VBW soft key and the MANUAL

soft key. Use the Up/down arrow key to

select 3 kHz. Press

ENTER to set the

video bandwidth to 3 kHz.

9. Press the

FREQ/DIST key and the CENTER

soft key.

10. Enter 1000 and press the

ENTER key to

set the center frequency to 1000 MHz.

11. Press the SPAN soft key and enter 0.1.

Press the

ENTER key to set the span to

0.100 MHz.

12. Press the

AMPLITUDE key.

13. Press the

REF LEVEL soft key and enter

–

27. Press ENTER to set the reference

level to –27 dBm.

14. Press the

MARKER key, then the M1 soft

key.

15. Press

EDIT and enter 1000. Press ENTER

to set the M1 marker frequency to 1000

MHz.

16. Press the BACK soft key and the M2 soft

key.

17. Press

EDIT and enter 1000.03. Press

ENTER to set the M2 marker frequency to

1000.03 MHz (30 kHz higher than the

center frequency).

18. Press the

DELTA (M2-M1) soft key.

19. Press the

RUN/HOLD key and read and

record the D 2 reading

20. Press the RUN/HOLD key to read and re

-

cord five values, then calculate the aver

-

age of the five recorded values.

21. Substract 40 dB from the average value

and verify that the result is £ –75

dBc/Hz. (For example: –35 dBc measured

– 40 dB = –75 dBc/Hz.)

22. (For example: –35 dBc measured +

(-40 dB) = –75 dBc/Hz.)
