Using Pulse Modulation for All Models with Options UNU, UNW, 320
The Basic Procedure
The Basic Procedure
1. Preset the signal generator.
2. Set the carrier (RF) frequency.
3. Set the RF amplitude.
4. Configure the modulation:
a. Set the pulse source: Press Pulse > Pulse Source > selection
b. Set the parameters for the selected pulse source:
5. Turn on the modulation: Pulse Off On softkey to On.
