Pulse Current Mode:
The Pulse Current Mode sets the instrument to display high, low, or aver-
age pulse-current measurements and to return these readings over the bus. The
Model 2304 can perform current measurements on 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.
Figure 4 illustrates the high, low, and average measurements of a pulse.
The high measurement is triggered on the rising edge of the pulse 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 the integration covers both the high and low periods of the
pulse, as specified by the average measurement time settings. The Model 2304 com-
putes one measurement parameter (high, low or average) at a time. The desired
measurement mode can be selected with the
and
buttons on the front panel.
