Configuring Pulse Modulation

Using the following procedure you will learn how to create a pulse-modulated RF carrier with
the following characteristics:
• RF output frequency set to 18 GHz
• RF output amplitude set to 0 dBm
• pulse period set to 100.0 µsec
• pulse width set to 24.0 µsec
• pulse source set to internal free-run
Setting the RF Output Frequency
1. Press .
Preset
2. Press >
Frequency
The FREQUENCY area of the display now reads 18.000 000 000 00 GHz.
Setting the RF Output Amplitude
Press > >
Amplitude 0
The AMPLITUDE area of the display now reads 0.00 dBm.
Setting the Pulse Period and Width
1. Press >
Pulse Pulse Period
This sets the pulse period to 100 microseconds.
2. Press >
Pulse Pulse Width
This sets the pulse period to 24 microseconds.
Activating Pulse Modulation
Follow these remaining steps to output the pulse-modulated signal.
1. Press
Pulse Off On
This activates pulse modulation. The Pulse annunciator is activated indicating that you
have enabled pulse modulation.
2. Press .
RF On/Off
The RF ON annuciator is activated, the signal is now available at the RF OUTPUT.
