Enabling Offset
Compensation
The MEASure and CONFigure commands turn offset compensation off.
The command used to turn offset compensation on is:
RESistance:OCOMpensated mode
where:
mode
= ON (offset compensation is enabled) or OFF (offset compensation
is disabled).
Querying the Offset
Compensation Mode
The offset compensation mode is queried with:
RESistance:OCOMpensated?
See Chapter 5 for additional information.
Triggering the Multimeter
The E1326B/E1411B multimeter operates in an idle state, a wait-for-trigger
state, and a triggered state. Configuration of the multimeter and its trigger
system occurs while the multimeter is in the idle state. When the
multimeter is ready to make a measurement, it is placed in the
wait-for-trigger state. When the trigger is received, the multimeter is placed
in the triggered state and a measurement is made. If the multimeter is
programmed to make one measurement per trigger, it returns to the idle
state once the measurement completes. If the multimeter is programmed for
multiple measurements per trigger or is programmed is to receive multiple
triggers, those conditions must be satisfied before it returns to the idle state.
Additionally, the multimeter’s trigger system consists of two loops - the
trigger count loop and the sample count loop. The sample count loop is the
faster of the two and can sustain 13 K samples per second as indicated in
Table 4-6 on page 110. The trigger count loop is slower due to the
following:
• The multimeter has a 512 by 16 bit buffer.
• In 10 µs aperture mode, the buffer holds 512 readings.
• For other aperture modes, the buffer holds 256 readings.
– for less than 512 readings, limitations by the multimeter occur
– for greater than 512 readings, limitations by the command
module occur
Figure 4-1 summarizes the multimeter’s trigger system. The trigger system
commands in the figure are covered on the following pages.
