SENSe:CURRent:RANGe
This command selects the dc current measurement range. All models have two current measurement
ranges:
High Range: 0 through MAX (see Table 4-3)
Low Range: 0 through 0.02 A (all models)
The High range covers the full current measurement capability of the instrument. The Low range
measures currents up to a maximum of 20 mA. This increases the low current measurement sensitivity for
greater accuracy and resolution. The value that you program with SENSe:CURRent:RANGe must be the
maximum current that you expect to measure. The instrument will select the range that gives the best
resolution. The crossover value is 20 mA. When queried, the returned value is the maximum current that
can be measured on the range that is presently set.

This command lets you select the type of detector used for output current measuremants. Two choices for
detecting current measurements are available:
ACDC
This is the preferred choice for all dynamic current measurements. When ACDC is selected,
the measured output current includes the current that flows in the instrument’s output
capacitor. It is especially important to use ACDC detection when measuring pulse or other
waveforms with frequency contents greater than several kilohertz.
DC
Select
DC
only if you are making dc current measurements and you require a dc measurement
offset accuracy better than 2mA on the High current measurement range. When DC is
selected, the component of output current that is supplied by the instrument’s output filter is not
sensed. Note that this selections gives inaccurate results on current waveforms with frequency
contents greater than several kilohertz.
NOTE: This command only applies to the High current measurement range.
