SENSe:CURRent:DETector

Agilent 66311B/D, 66309B/D only

This command lets you select the type of detector used for output current measurements. 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 selection gives inaccurate results on current waveforms with frequency contents greater than several kilohertz.

NOTE: This command only applies to the High current measurement range.

Command Syntax

Parameters

ACDC or DC

 

*RST Value

ACDC

 

Examples

SENS:CURR:DET ACDC

SENS:CURR:DET DC

Query Syntax

SENSe:CURRent:DETector?

 

Returned Parameters

<CRD>

 

SENSe:CURRent:RANGe

Agilent 66311B/D, 66309B/D only

This command selects the dc current measurement range:

High Range: 0 through MAX (see Table 8-3)

Low Range: 0 through 0.02 A

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.

Command Syntax

SENSe:CURRent[:DC]:RANGe[:UPPer] <NRf+>

Parameters

0 through MAX (see table 8-3)

Unit

A (amperes)

*RST Value

MAX (high range)

Examples

SENS:CURR:RANG 4.0

Query Syntax

SENSe:CURRent:RANGe?

Returned Parameters

<NR3>
