Trigger Out Signal
A "trigger out" signal is provided on the rear-panel Ext Trig connector (used with burst and sweep only). When ena-
bled, a TTL-compatible pulse with either a rising edge (default) or falling edge is output from this connector at the begin-
ning of the sweep or burst.
l When the Internal (immediate) trigger source is selected, the instrument outputs a square waveform with a 50%
duty cycle from the Ext Trig connector at the beginning of the sweep or burst. The frequency of the waveform cor-
responds to the specified burst period or total sweep time.
l When the External trigger source is selected, the instrument disables the "trigger out" signal. The Ext Trig con-
nector cannot be used for sweep or burst and trigger out at the same time (an externally-triggered waveform uses
the same connector to trigger the sweep or burst).
l When Manual trigger source is selected, the instrument outputs a pulse (>1 μs pulse width) from the Ext Trig con-
nector at the beginning of each sweep or burst.
