Configuring Pulse Modulation (Option UNU/UNW)

Configuring Pulse Modulation (Option UNU/UNW)

In this example, you will learn how to create a gated, pulse–modulated RF
carrier with an external trigger.

To Set the RF Output Frequency

1. Press Preset.
2. Press Frequency > 2 > GHz.

To Set the RF Output Amplitude

Press Amplitude > 0 > dBm.

To Set the Pulse Period, Width, and Triggering

1. Press Pulse > Pulse Period > 100 > usec.
2. Press Pulse > Pulse Wid th > 24 > usec.
3. Press Pulse > Pulse Source > Int Gated.
4. Connect a TTL signal to the Trigger In connector on the rear panel of the
The signal generator is now configured to output a 0 dBm, pulse–modulated
carrier at 2 GHz with a 100-microsecond pulse period and 24-microsecond
pulse width. The pulse source is set to internal gated. (Notice that Internal Free
Run is the default for the Pulse Source softkey.)

To Activate Pulse Modulation

Follow these remaining steps to output the pulse–modulated signal.
1. Press Pulse Off On to On.
2. Press RF On/Off.
The Pulse and RF ON annunciators are now displayed. This indicates that you
have enabled pulse modulation and the signal is now being transmitted from
the RF OUTPUT connector. The TTL trigger signal state will control pulse
modulation output.
Triggering Simultaneous Pulses from Two PSGs Using an Internal or
an External Pulse Source
Two PSG pulse generators can be triggered simultaneously using the PSG
internal pulse generator or using an external pulse source. The pulse from
PSG1 is triggered internally or by the external pulse generator and the pulse
from PSG2 is triggered using the SYNC OUT signal from PSG1. Each PSG can

signal generator. To configure the trigger signal polarity, Press Utility >
Instrument Ad justments > Signal Polarity Setup > Trigger In Polarity.
