Chapter 2 — Spectrum Analyzer Verification 2-7 Resolution Bandwidth Accuracy Verification
MS2720T MM PN: 10580-00342 Rev. D 2-13
Procedure
1. Connect the external 10 MHz Reference both to the MG3692x or MG3695C Synthesized Signal Generator
and to the Spectrum Master MS2720T, as shown in Figure 2-1.
2. Set the MS2720T to Spectrum Analyzer mode and then Preset the instrument. Press the Shift key, the
Sweep (3) key, Sweep Mode submenu key and then the Performance submenu key.

Center Frequency: 1.0 GHz
Reference Level: –10 dBm
Atten Lvl: 0dB
4. Set the MG3692x or MG3695C to 1 GHz CW, with an output level of –30 dBm. Apply the signal to the
Spectrum Analyzer RF In connector of the MS2720T.
5. On the MS2720T, set the Span to 20 MHz.
6. Press the BW main menu key and set the RBW to 10 MHz.
7. Press the VBW submenu key set to 1MHz.
8. Under the Measure menu, press (Shift (4), press Power and Bandwidth, press OCC BW and set it to On.
9. Press the dBc submenu key and enter 3.
