3-2 Pulse Current Measurements

Overview

The power supply can perform current measurements for pulsing loads. The built-in measure-

ments include:

• Peak measured current — measures the peak (high) current of the pulse train.

• Idle measured current — measures the idle (low) current of the pulse train.

• Average transmit current — measures the average current of the pulse train.

NOTE For Models 2303 and 2303B, pulse-measurements are automatically performed on

the 5A range. For Model 2303-PJ, pulse-current measurements can be performed on

either the 5A range or 500mA range.

The high, low, and average measurements of a pulse are illustrated in Figure 3-1. The high

measurement is triggered on the rising edge of the pulse, and an integration 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 the integration is speciﬁed by the

average measurement time setting.

NOTE Another measurement of pulse currents, digitization, is available over the bus. Refer

to “Pulse current digitization” in “SCPI programming” for details.
