Free Run

–The pulse generator produces Single, Doublet, Triplet, or Quadruplet

pulse modulation waveforms at the internal pulse repetition rate. Pulse delay

(D1) is

not

available in this trigger mode.

Delayed

–The pulse generator produces Single, Doublet, Triplet, or Quadruplet

pulse modulation waveforms delayed by pulse delay (D1) at the internal pulse

repetition rate.

Triggered

–The pulse generator is triggered by an external trigger to produce

Single, Doublet, Triplet, or Quadruplet pulse modulation waveforms. Pulse de-

lay (D1) is

not

available in this trigger mode.

Triggered w/delay

–The pulse generator is triggered by an external trigger to

produce Single, Doublet, Triplet, or Quadruplet pulse modulation waveforms de-

layed by pulse delay (D1).

Gated

– An external pulse gates the internal pulse generator on and off. When

gated on, the pulse generator produces a Single pulse modulation waveform at

the internal pulse repetition rate. Doublet, Triplet, and Quadruplet pulse modes

are

not

available in this trigger mode.

For proper operation, the period of the external pulse must be greater than the

sum of the pulse repetition rate and pulse width of the internal pulse modula-

tion waveform. To prevent relative timing jitter, the external gating pulse

source can be synchronized with the internal pulse generator by using the

10 MHz REF OUT

signal output (MG369XB rear panel) as a frequency reference

for the external generator.
