Frequency Counter Procedure (N5161A1/62A1/81A/82A)
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).
