Pulse Building

Multiple Pulses

This section describes the minimum times supported when generating two or more pulses in a pattern.

The following timing constraints must be met when generating two or more pulses:

  1. The total signal period must be an integer multiple of the Arb waveform granularity as described for the Single Pulse configuration.

    2. M9484C VXG

    = 0.333 ns

  2. The individual times can be set to anything including zero. The actual time resolution is dependent on the Arb sampling rate.

This means that except for the very last PRI, all of the pulse on times, pulse edge times, and pulse off times, are generated with a time resolution equal to the Arb sample period. The on times, edge times and off times can be set to zero. Setting the pulse PRI time equal to the pulse on time makes the pulse off time equal to zero and two pulses will touch each other. The last PRI is rounded to insure that the Arb waveform granularity requirement is met.

When the Pulse shape is Custom Profile or Custom I/Q, the rising edge and falling edge times are assumed to be zero. The pulse On Time is equal to the Custom Profile or Custom I/Q data.
