CH<x>:PROBECOntrol

This command sets or queries multirange probe range-control policy preference of the probe that is attached to CH<x>. The
channel number is specified by x.

Syntax

CH<x>:PROBECOntrol {AUTO|MANual}
CH<x>:PROBECOntrol?

Arguments

AUTO

 sets the values. The probe range is automatically calculated.

MANual

 allows you to select various valid values for the probe connected to a

particular channel.

Examples

CH2:PROBECONTROL AUTO

 sets the values and the probe range is

automatically calculated.

CH2:PROBECONTROL?

 might return 

MANUAL

 indicating that you can select

various valid values for the probe connected to channel 2.

CH<x>:PROBEFunc:EXTAtten

This command is used to specify the attenuation value as a multiplier to the given scale factor on the specified channel. The
channel is specified by x.

The query form of this command returns the user-specified attenuation.

Syntax

CH<x>:PROBEFunc:EXTAtten <NR3>
CH<x>:PROBEFunc:EXTAtten?

Arguments

<NR3>

 is the attenuation value, which is specified as a multiplier in the range from

1.00E-10 to 1.00E+10.

Examples

CH1:PROBEFUNC:EXTATTEN 167.00E-3

 specifies an external

attenuation, which is connected between the your input signal and the input of the
probe attached to Channel 1.

CH2:PROBEFUNC:EXTATTEN?

 might return 

1.0000E+00

, indicating that

the probe attached to Channel 2 is connected directly to the user's signal.

CH<x>:PROBEFunc:EXTDBatten

This command sets or queries the input-output ratio (expressed in decibel units) of external attenuation or gain between the
signal and the instrument input channels. The channel is specified by x.

The query form of this command returns the user-specified attenuation in decibels.

Syntax

CH<x>:PROBEFunc:EXTDBatten <NR3>
CH<x>:PROBEFunc:EXTDBatten?

Arguments

<NR3>

 is the attenuation value, which is specified in the range from -200.00 dB to

200.00 dB.

Examples

CH3:PROBEFUNC:EXTDBATTEN 2.5

 specifies an external 2.5 dB

attenuator on Channel 3.

CH1:PROBEFUNC:EXTDBATTEN?

 might return 

2.5000E+00

, indicating

that the attenuation for Channel 1 is 2.5 dB.

CH<x>:PROBEFunc:EXTUnits

This command sets the unit of measurement for the external attenuator of the specified channel. The channel is specified by
x. The alternate units are used if they are enabled. Use the 

CH<x>:PROBEFunc:EXTUnits:STATE

 command to

enable or disable the alternate units.
