SENSe:VOLTage<n>[:DC]:RANGe:AUTO

Syntax: SENSe:VOLTage<n>[:DC]:RANGe:AUTO <Boolean>

<n> [1] 2 3 4

Note: Channel 3 and 4 not applicable for PM33x0B.

Query form: SENSe:VOLTage<n>[:DC]:RANGe:AUTO?

Response: 0 1

0Autoranging attenuator channel <n> switched off.

1Autoranging attenuator channel <n> switched on.

Description:

Switches the autoranging function of channel <n> on or off. In the analog mode, the error message -221 "Settings conflict;Digital mode required" is generated. The autoranging attenuator function is automatically switched off when the following occurs:

-Attenuation value is programmed (SENSe:VOLTage<n>:RANGe:PTPeak).

-A channel is switched off (SENSe:FUNCtion:OFF "XTIMe:VOLTage<n>").

-The Main Time Base (MTB) is switched off.

-The applicable channel addition function, e.g., CH1+CH2, is switched on

(SENSe:FUNCtion:ON "XTIMe:VOLTage:SUM 1,2").

After a *RST command, autoranging attenuation for all channels is switched off.

Note: Switching the autoranging attenuator on for a channel, automatically sets the input signal coupling for that channel to AC (INPut<n>:COUPling AC). Also the main timebase is switched from variable (VAR) into 1-2-5 step mode.

Example:
Send → *RST	Switches CH1 on.
Send → SENSe:FUNCtion:ON 'XTIMe:VOLTage2'	Switches CH2 on.
Send → INITiate:CONTinuous ON	Sets Auto run mode.
Send → SENSe:VOLTage2:RANGe:AUTO ON	Autoranging CH2.

Send → SENSe:FUNCtion:ON 'XTIMe:VOLTage:SUM 1,2'

Switches CH1 + CH2 on. The result is that the addition of input channels 1 and 2 is switched on (CH1+CH2) and autoranging attenuator channel 2 switched off.

Front panel compliance:

The SENSe:VOLTage<n>:RANGe:AUTO command is the remote equivalent of the four front panel AUTO RANGE keys (one for each channel).
