Burst Mode
• Remote Interface Operation:
TRIGger:SOURce {IMMediate|EXTernal|BUS}
Use the following command to specify whether the function generator
triggers on the rising or falling edge of the Trig In connector.
TRIGger:SLOPe {POSitive|NEGative}
See "Triggering" on page 115 for more information on triggering.
Trigger Out Signal
A "trigger out" signal is provided on the rear-panel Trig Out connector
(used with burst and sweep only). When enabled, a TTL-compatible pulse
waveform with either a rising edge (default) or falling edge is output from
the Trig Out connector at the beginning of the burst.
• When the Internal (immediate) trigger source is selected the function
generator outputs a square waveform with a 50% duty cycle from the
Trig Out connector at the beginning of the burst. The frequency of the
waveform is equal to the specified burst period.
• When the External trigger source is selected, the function generator
automatically disables the "trigger out" signal. The Trig Out connector
cannot be used for both operations at the same time (an externally-
triggered waveform uses the same connector to trigger the burst).
• When the Manual trigger source is selected, the function generator
outputs a pulse (>1 µs pulse width) from the Trig Out connector at the
beginning of each burst.
• Front-Panel Operation: After enabling bursts, press the Trigger Setup
softkey. Then select the desired edge by pressing the Trig Out softkey.
• Remote Interface Operation:
OUTPut:TRIGger:SLOPe {POSitive|NEGative}
OUTPut:TRIGger {OFF|ON}
