Filter

Filtering cannot be used while the Model 2430 is in the Pulse Mode. You can configure the
filter, but you cannot enable it. Pressing the FILTER key displays the "Invalid in Pulse
Mode!" message. For remote operation, the [:SENSe]:AVERage[:STATe] <b> command
(which is used to enable the filter) causes error +831: Invalid in Pulse Mode.
Auto range
Measurement auto range cannot be used (enabled) while in the Pulse Mode. Pressing the
AUTO range key displays the "Invalid in Pulse Mode!" message. For remote operation,
the [:SENSe] ... :RANGe:AUTO <b> commands (which are used to enable/disable auto
range) cause error +831: Invalid in Pulse Mode.
Concurrent measurements
For remote operation, more than one function can be measured simultaneously while
in the DC Mode. However, in the Pulse Mode, only one function can be measured for
each pulse. The [:SENSe]:FUNCtion:CONCurrent <b> command (which enables/
disables concurrent measurements) causes error +831: Invalid in Pulse Mode. The
[:SENSe]:FUNCtion[:ON]:ALL command will select the ohms function. See
"SENSe1 subsystem" -
measurements.
Ohms source readback
For DC Mode operation, ohms source readback can be enabled. The instrument measures
the actual source value for ohms measurement and then uses that measured value for the
reading calculation. For the Pulse Mode, ohms source readback cannot be enabled.
Section 4 covers "Ohms source
NOTE
Make sure that the source is not in compliance when taking pulse-ohms
readings.
Toggle key
For the DC Mode, the TOGGLE key manipulates display readings while the output is on.
For the Pulse Mode, the output is only on for very short periods of time (pulse width).
Therefore, the TOGGLE key is disabled in the Pulse Mode.
