2-2 Frequency Accuracy Verification Spectrum Analyzer Verification
2-2 PN: 10580-00255 Rev. J MT8212E and MT8213E MM
2-2 Frequency Accuracy Verification
The following test is used to verify the CW frequency accuracy of the Spectrum Analyzer in the
MT821xE Cell 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.
2. Turn On the 10 MHz Reference Standard and the Anritsu MG3692X Synthesized Signal Source.
3. Set the MG3692X output to 1 GHz CW, with an RF Output Level of –30 dBm.
4. Connect the output of the source to the RF In of the Cell Master.
5. Turn On the Cell Master.
6. 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.
7. Press the Shift key, then the Preset (1) key, and then the Preset submenu key to reset the instrument to
the default starting conditions.
8. Press the Shift key, then the Sweep (3) key, then the Sweep Mode key, and then the Performance
submenu key.
9. Press the Amplitude main menu key, and then press the Reference Level submenu key.
10. Use the keypad to enter –10 and press the dBm submenu key.
11. Press the Span submenu key, use the keypad to enter 10, and press the kHz submenu key.
12. Press the BW submenu key and press the RBW submenu key.
13. Use the keypad to enter 100
and press the Hz submenu key.
14. Press the VBW submenu key, use the keypad to enter 30, and then press the Hz submenu key.
15. Press the Freq main menu key and press the Center Freq submenu key.
16. Use the keypad to enter 1 and press the GHz submenu key.
17. Press the Marker main menu, then the More submenu key, set Counter Marker to On, press the Back
submenu key, and then press the Peak Search submenu key.
18. Verify that the marker frequency is 1GHz±1.5kHz(±1.5ppm) and record in Table A-1, “Spectrum
Analyzer Frequency Accuracy” on page A-2.
19. Set the MG3692X frequency to 3.9 GHz and then 5.9 GHz (for MT8213E only).
20. Set the MT821xE center frequency to 3.9 GHz and then 5.9 GHz (for MT8213E only).
Caution Do not connect the external 10 MHz Reference to the Cell Master.
Note Without the Counter Marker On, the frequency resolution will not allowviewing the kHz accuracy.
