Agilent Technologies 5988-7401EN manual Timing of Generated Signals

Using the Agilent 81133A/81134A Pulse Generator Timing of Generated Signals

NOTE The trigger divider does not take the frequency divider of the channels into account. For a frequency divider of n, n trigger pulses are generated for each data packet, starting with the first edge of bit 0 of the data packet.

To get one trigger pulse per data packet when the channel divider factor is not equal to 1, the trigger mode must set to Trigger on pulse and the divider to n x X, where n is the frequency divider and X is the data length. For example, if the data length = 32 bits and the frequency divider of channel 1 = 2, the frequency divider of the trigger output has to be 64.

The trigger output can be enabled/disabled. The levels of the trigger output can be set as:

•Low Level – High Level

•Amplitude – Offset

Timing of Generated Signals

The following sections provide information about the signals that can be generated and shows the typical timings.

The instrument allows you to generate the following signals:

•Clock signals

•Pulses

•Data patterns

•PRBS

•Started bursts

•Repetitive bursts

NOTE You can also set the frequency divider for all channels. The minimum frequency must remain above 15 MHz.
