Programming examples: making voltage measurements with the DVM
The following command sequence demonstrates how to measure voltage applied to the DVM
input of the power supply:
Battery channel (#1)
Charger channel (#2)
Pulse current mode
Description
The Model 2306 can perform pulsed current measurements for dynamic loads. The built-in
measurements include:
1. Peak measured current - measures the peak (high) current of the pulse train.
2. Idle measured current - measures the idle (low) current of the pulse train.
3. Average transmitted current - measures the average current of the pulse train.
The high measurement is triggered on the rising edge of the pulse (Figure 5) and an integra-
tion is performed for the time specified for the high measurement. The falling edge of the pulse
triggers the low measurement, and an integration is performed for the time specified for the low
measurement. An average measurement is triggered on the rising edge, and covers both the high
and low periods of the pulse as specified by the average measurement time setting. The
Model 2306 computes one measurement parameter, high, low, or average, at a time. The desired
measurement mode on the front panel is selected with the up and down arrow keys.
