Trigger out
If your instrument is a two-channel model, the trigger output connector and signal of the instrument
are linked to the run mode and function selected in CH1.
To set up trigger out:
1. Connect the AFG31000 Series front-panel Ch 1 TRIGGER output connector to the external
TRIGGER input connector of the oscilloscopes. The TRIGGER output connector provides the
trigger signal for oscilloscopes.
2. Select Basic.
3. Select Continuous mode on the CH1 drop-down menu on the touchscreen.
4. Select Square waveform on the drop-down menu of the touchscreen. The output is a square
waveform with the rising edge at the start of each waveform period. When an output frequency is
higher than 4.9 MHz, some restrictions are applied.
5. Select Sweep mode on the CH1 drop-down menu on the touchscreen. When the Repeat or
Trigger sweep mode and internal trigger source are selected, the trigger output is a square
waveform with the rising edge at the start of each sweep.
6. Select Modulation mode on the CH1 drop-down menu on the touchscreen. When an internal
modulation source is selected, the trigger output is a square waveform with the same frequency
as the modulating signal. When an external modulation source is selected, the trigger output is
disabled.
7. Select Burst mode on the CH1 drop-down menu on the touchscreen. When an internal trigger
source is selected, the trigger output is a square waveform with the rising edge at the start of
each burst period. When an external trigger source is selected, the trigger output is high during
the time the trigger input is high.
NOTE. When a frequency setting of an output waveform is higher than 4.9 MHz, a divided frequency that
is lower than 4.9 MHz is output from the Trigger Out (see the following table).

NOTE. The Trigger Out signal cannot be output when the instrument outputs a continuous signal higher
than 50 MHz. When the instrument outputs a modulation waveform, the Trigger Output signal cannot be
output if you select External as the modulation source.
