Trig, Gate and Burst
Characteristics
Maintenance and Performance Checks 5-12
Triggered - Each transition at the front panel TRIG IN connector
stimulates the Model 3151/3151A to generate one complete output
waveform.
Gated - External signal at the TRIG IN connector enables the Model
3151/3151A output. The last cycle of the output waveform is always
completed.
Burst - Each transition at the front panel TRIG IN connector
stimulates the Model 3151/3151A to generate a burst of pre-selected
number of cycles.
Equipment: Pulse/function generator (8021), oscilloscope.
