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
µ
sec
• pulse width set to 24.0
µ
sec
• pulse source set to internal free-run
Setting the RF Output Frequency
1. Press
Preset.
2. Press
Frequency > 18 > GHz.
The FREQUENCY area of the display now reads 18.000 000 000 00 GHz.
Setting the RF Output Amplitude
Press
Amplitude > 0 > dBm.
The AMPLITUDE area of the display now reads 0.00 dBm.
Setting the Pulse Period and Width
1. Press
Pulse > Pulse Period > 100 > usec.
This sets the pulse period to 100 microseconds.
2. Press
Pulse > Pulse Width > 24 > usec.
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.
