Jitter Modulation Using the Agilent 81133A/81134A Pulse Generator

Agilent 81133A/81134A Pulse Generator User’s Guide, January 2005 83

Jitter Modulation

The external source for jitter modulat ion is applied to the delay

control input. Jitter modulation can be turned on and off individually

for each channel. Either one of t wo fixed sensitivities can be selected.

The source for the jitter modulation input is assumed to be either a

function generator or an arbitrary waveform generator. Both have the

capability of setting the output levels. Therefore, the instrument h as no

capabilities of adjusting the jitter modulation i nput.

Saving and Recalling Settings

For permanently saving the instrument setting, nine save/recall

registers are provided.

All parameters are saved, including the data. User interface specifics,

such as the current visible page, are not saved.

When the instrument is turned on, the last used setting is restored.
