Support Functions Trigger Function Trigger Input The 4155C/4156C can receive an edge trigger (TTL level, pulse width approximately 10 μs) from external instruments via the trigger input terminal, and initiate a sweep or sampling measurement. Following figure shows examples of externally-triggered sampling and sweep measurements. For the trigger polarity, you can select positive or negative. Figure 8-8 Examples of Externally Triggered Measurements After you press the Single, Repeat, or Append front-panel key, the 4155C/4156C waits for the trigger signal only once. When the 4155C/4156C receives the trigger signal, the 4155C/4156C starts measurements. For staircase sweep measurements, you can specify the step delay time shown in Figure 8-8. 8-44 Agilent 4155C/4156C User’s Guide Vol.2, Edition 6
