2-6 PN: 10580-00253 Rev. J S3xxE MM
2-4 Resolution Bandwidth Accuracy Verification
The following test is used to verify the resolution bandwidth accuracy of the spectrum analyzer in the S332E
and S362E Site Master.
Equipment Required
• Anritsu MG3692X Synthesized Signal Source
• 10 MHz Reference Standard
• Anritsu 34RKNF50 50 ohm Adapter
• Anritsu 15NN50-1.5C RF Coaxial Cable
• BNC male to BNC male Coaxial Cable
Procedure
1. Connect the 10 MHz reference source to the Anritsu MG3692X Synthesized Signal Source and the S332E
or S362E Site Master.
2. Turn on the MG3692X, set the frequency to 1GHz CW and Level to –30 dBm.
3. Connect the output of the Anritsu MG3692X Synthesized Signal Source to the S332E or S362E
Spectrum Analyzer RF In.
4. Turn on the S332E or S362E Site Master.
5. Press the Shift key and then the Mode (9) key. Rotate the knob to highlight Spectrum Analyzer and then
press the Enter key to switch to Spectrum Analyzer mode.
6. Press the Shift key, the Preset (1) key, and then the Preset soft key to reset to the default starting
conditions.
7. Press the Shift key, the Sweep (3) key, then the Sweep Mode soft key, and press the Performance soft key.
8. Press the Amplitude soft key and then press the Reference Level soft key.
9. Use the keypad to enter –10 and press the dBm soft key.
10. Press the Atten Lvl soft key and enter 0, then press the dB soft key.
11. Press the Scale soft key and enter 10, then press dB/div soft key.
12. Press the Freq soft key and press the Center Freq soft key.
13.
Use the keypad to enter 1 and press the GHz soft key.
RBW Test
14. Press the Span soft key, use the keypad to enter the span listed in the test records. Refer to the
Span column of Table A-4, “Spectrum Analyzer Resolution Bandwidth Accuracy”.
15. Press the BW soft key and press the RBW soft key.
16. Use the keypad to enter 3 and press the MHz soft key.
17. Set the VBW from the value listed in the test records. Refer to the VBW column of Table A-4.
18. Press the Shift key, press the Measure (4) key, press the Power and Bandwidth soft key and then press the
OCC BW soft key.
19. Press the dBc soft key and enter 3, then press the Enter key.
20. Press the OCC BW On/Off soft key to turn on occupied bandwidth.
21. Record the OCC BW reading in the test records. Use the Measured Value column of Table A-4.
22. Verify that the OCC BW reading frequency is within 10 % of the RBW.
23. Repeat Step 14 through Step 22 for the other settings and record in Table A-4.
