Triggering a Waveform 
Example: External Triggering
Use the following example to set the signal generator to output a modulated RF signal 
100 milliseconds after a change in TTL state from low to high occurs at the PATT TRIG IN rear panel 
BNC connector
1. Connect the signal generator to the function generator as shown above.
2. Configure the RF output:
• Set the desired frequency.
• Set the desired amplitude.
• Turn on the RF output.
3. Select a waveform for playback (sequence or segment):
a. Press  Mode > Dual ARB > Select Waveform.
b. In the Segment On or Sequence On column, highlight a waveform.
c. Press  Select Waveform.
4. Generate the waveform:  
Press  ARB Off On until On highlights.
5. Set the waveform trigger as follows:
a. Trigger Type: single 
Press  Trigger Type > Single > No Retrigger
b. Trigger Source: external 
Press  Trigger Source > Ext
c. Input connector: Rear panel Patt Trig In BNC 
Press  Ext Source > Patt Trig In 1.
d. External Trigger Polarity: positive 
Press  Ext Polarity until Pos highlights
e. External Delay: 100 ms 
Press  More > Ext Delay until On highlights 
Press  Ext Delay Time > 100 > msec
6. Configure the Function Generator:
• Waveform: 0.1 Hz square wave
• Output Level: 3.5V to 5V.
