Only one relative frequency range and accuracy verification test is required. Either use the frequency counter procedure on page 10 or the
spectrum analyzer test procedure in this section.
Procedure
1. Connect the equipment as shown.
2. Verify that the spectrum analyzer is locked to the 10 MHz external reference frequency.
3. Align the spectrum analyzer: Press System > Alignment > Align All Now.
4. Preset the signal generator: Press
Preset.
5. Turn modulation off: Press the
Mod On/Off so that the MOD On/Off LED turns off.
6. Set the amplitude: Press
Amplitude and enter 0 dBm.

The N5161A/62A performs the identical internal tests as in the MXG via a LAN connection to a Web Server. The front panel displays all hardkeys, softkeys and test results
as depicted in the illustration. For information on Web-Enabled Control refer to
“Accessing the MXG Web-Enabled Page” on page 1-18 and to the Programming
Guide
