is selected).
 You cannot specify a burst period that is too short for the instrument to output with the specified
burst count and frequency. If the burst period is too short, the instrument will increase it as
needed to continuously re-trigger the burst.
Start Phase
Start phase of the burst, from 0 to +360 degrees (default 0).
Burst Trigger Source
In triggered burst mode:
 The instrument outputs a waveform of the specified number of cycles (burst count) when a
trigger received. After the specified number of cycles have been output, the instrument stops
and waits for next trigger.
 Internal: the instrument outputs continuously when burst mode is enabled.
 EXTernal: the instrument accepts a hardware trigger at the front-panel TRIG connector. The
instrument outputs one burst of the specified number of cycles each time TRIG receives a TTL
pulse with the proper polarity (SOURce<n>:BURSt:TRIGger:SLOPe POSitive|NEGative).
External trigger signals during a burst are ignored.
 EXTernal or BUS: burst count and burst phase remain in effect, but burst period is ignored.

Gate Polarity
Select the gate as high level or low level on the front panel EXT BNC connector to output burst
sequence.

3.9 Trigger System

This section describes the instrument's triggering system.
Trigger Overview
This triggering information applies to sweep and burst only. You can issue triggers for sweeps or
bursts using internal triggering, external triggering, timer triggering, or manual triggering.
Internal (default): instrument outputs continuously when sweep or burst mode is selected.
External: uses front-panel TRIG connector to control sweep or burst. The instrument initiates
