Test Setup
1. Connect the equipment as shown.
2. Preset the signal generator: Press Preset.
3. Turn modulation off: Press the
Mod On/Off so
that the MOD On/Off LED turns off.
4. Set the amplitude:
Press
Amplitude and enter 0 dBm.
5. Turn RF on: Press
RF On/Off so that the
RF On/Off LED lights.
6. Verify that the frequency counter is locked to
the 10 MHz external reference frequency
(±1 Hz).
7. For maximum accuracy, set the gate time on
the frequency counter to >5 seconds.
(Press
Gate & ExtArm twice and use the arrow
keys to set the value.)
8. Set the frequency: Press
Frequency and set the
signal generator to the first frequency listed
in Table 3-2.
9. Confirm that the measured frequency is
within the limits listed.
1.For the N5161A/62A these softkey menus and
features are only available through the
Web-Enabled MXG or through SCPI commands.
Refer to “Configuring the MXG ATE” on page 7, to
the Programming Guide, and to the SCPI
Command Reference.
10. Repeat step 8 and step 9 for all of the
frequencies in the table that are within the
frequency range of your signal generator.
NOTE For frequencies <200 MHz, use Channel 3
on the frequency counter
(press Freq Ratio until CH3: displays).
