Front panel operation
The pulse measurement period T can be selected manually or be automatically set by the
Model 2306. First, the user must specify a trigger level that serves as a threshold to initiate inte-
gration process, i.e., at t = 0. Once the trigger level is selected, the output is turned on and the
pulsed load is operational, the 2306 can be prompted to automatically determine the high time,
low time, and average time in pulsed current mode according to Figure 5. These parameters may
also be set manually from the front panel or over the GPIB bus.

The pulsed waveform in Figure 5 shows trigger level and the high, low, and average
times set by the Model 2306 using the auto-time feature.
