MEASure:ARRay:CURRent?

MEASure:ARRay:VOLTage?

These queries initiate and trigger a measurement and return an array containing either the digitized output current in amperes or output voltage in volts. The output voltage or current is digitized whenever a measurement command is sent or an acquisition trigger occurs. The time interval is set by SENSe:SWEep:TINTerval. The position of the trigger relative to the beginning of the data buffer is determined by SENSe:SWEep:OFFSet. The number of points returned is set by SENSe:SWEep:POINts.

NOTE: You can specify an optional maximum value parameter. The dc source will select the proper current range to measure the maximum current.

MEASure:CURRent?

MEASure:VOLTage?

These queries initiate and trigger a measurement and return either the output current in amperes or output voltage in volts. The total measurement time is specified by SENSe:SWEep:NPLCycles.

NOTE: You can specify an optional maximum value parameter. This lets you use a different current range for a single measurement without having to change current ranges.

SENS:SWE:NPLC

SENSe:CURRent:RANGe

This command selects one of the following dc current measurement ranges based on the value entered:

0.5 A

Enter values greater than 0.015A

15 mA

Enter values greater than 0.0005A up to 0.015A

0.5 mA

Enter values less than and up to 0.0005A

The programmed value must be the maximum current that you expect to measure. Crossover values are

0.5mA and 15 mA respectively. When queried, the returned value is the maximum dc current that can be measured on the range that is presently set.

Command Syntax

SENSe:CURRent[:DC]:RANGe[:UPPer] <Nrf>, (@<channel list>)

Parameters

The maximum current that you expect to measure (see table 6-3)

Unit

A (amperes)

*RST Value

0.5 A

Examples

SENS:CURR:RANG 0.4,(@1)
