To Set a Delayed, Positive Polarity, External Single Trigger
Using this procedure, you learn how to utilize an external function generator to apply a delayed
single-trigger to a custom multicarrier waveform.
1. Connect an Agilent 33120A function generator or equivalent to the signal generator PATT TRIGGER IN
port, as shown in Figure 6-1.
Figure 6-1
2. On the signal generator, press
Preset.
3. Press
Mode > Custom > Arb Waveform Generator.
4. Press
Multicarrier Off On until On is highlighted.
5. Press
Trigger > Single.
6. Press
Trigger > Trigger Setup >Trigger Source > Ext.
7. Press
Ext Polarity Neg Pos until Pos is highlighted.
8. Press
Ext Delay Off On until On is highlighted.
9. Press
Ext Delay Time > 100 > msec.
The Custom Arb Waveform Generator has been configured to play a single multicarrier waveform
100 milliseconds after it detects a change in TTL state from low to high at the PATT TRIG IN rear panel
connector.
10. Set the function generator waveform to a 0.1 Hz square wave at an output level of 0 to 5V.
