Sync Out - One for each channel
Multifunction output user definable or automatically selected to be any of the following:
Waveform Sync:
(all waveforms)
Position Markers:
(Arbitrary only)
Burst Done:
Sequence Sync:
Trigger:
Sweep Sync:
Phase Lock Out:
Output Signal Level:
Cursor/Marker Out
Adjustable output pulse for use as a marker in sweep mode or as a cursor in arbitrary waveform
editing mode. Can be used to modulate the Z−axis of an oscilloscope or be displayed on a
second 'scope channel.

A square wave with 50% duty cycle at the main waveform frequency, or
a pulse coincident with the first few points of an arbitrary waveform.
Any point(s) on the waveform may have associated marker bit(s) set
high or low.
Produces a pulse coincident with the last cycle of a burst.
Produces a pulse coincident with the end of a waveform sequence.
Selects the current trigger signal. Useful for synchronizing burst or
gated signals.
Outputs a pulse at the start of sweep to synchronize an oscilloscope or
recorder.
Used to phase lock two generators. Produces a positive edge at the 0°
phase point.
TTL/CMOS logic levels from typically 50Ω.
Adjustable from nominally 2V to 14V, normal or inverted; adjustable
width as a cursor.
600Ω typical
DC − 1MHz.
Threshold nominally TTL level; maximum input ±10V.
50ns, for Trigger and Gate modes; 50us for Sweep mode.
Selectable as high/rising edge or low/falling edge.
10kΩ
DC – 100kHz.
VCA: Approximately 1V pk−pk for 100% level change at maximum
output.
SCM: Approximately ± 1Vpk for maximum output.
Typically 1 kΩ.
DC − 8 MHz.
Approximately 2 Vpk−pk input for 20Vpk−pk output.
Typically 1kΩ.
