The Basic Procedure; Example - Agilent Technologies X Series User Manual

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:

Up to 2047 pulse cycles (elements) composed of both Pulse On and Pulse Off can be user defined.
5. Turn on the modulation: Pulse Off On softkey to On.
The the PULSE annunciator lights, indicating that you enabled modulation.
6. Output the modulated signal from the signal generator: Press the front panel RF On Off key.
The RF output LED lights, indicating that the signal is transmitting from the RF output connector.

Example

The following example uses the factory preset pulse source and delay.
A 2 GHz, 0 dBm carrier modulated by a 24 μs pulse that has a period of 100 μs.
Output:
1. Preset the signal generator.
2. Set the frequency to 2 GHz.
3. Set the amplitude to 0 dBm.
