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).
