3-2 Pulse Current Measurements
Overview
The power supply can perform current measurements for dynamic loads on either battery
channel (#1) or charger channel (#2). The built-in measurements include:
• Peak measured current — measures the pea
k (high) current of the pulse train.
• Idle measured current — measures the idle (low) current of the pulse train.
• Average transmit current — measures the a
verage current of the pulse train.
The high, low, and average measurements of a pulse are illustrated in Figu
re 3-1. The high
measurement is triggered on the rising edge of the pulse, and an integration is performed for the
time specif
ied 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. Each pulse current measurement reading will trigger on the
respective edge.
NOTE T
wo other measurements of pulse currents are available over the bus. See “Pulse
current digitization” on page 3-31 and “Pulse current STEP method (battery channel
only)” on page 3-32 for details.

High and average measurements triggered on leading edge of pulse
