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<n>:COUPling AC). Also the main timebase is switched from
variable (VAR) into 1-2-5 step mode.
Example:
→
Send *RST
→
SENSe:FUNCtion:ON 'XTIMe:VOLTage2' Switches CH2 on.
Send
→
Send INITiate:CONTinuous ON
→
Send SENSe:VOLTage2:RANGe:AUTO ON
→
Send SENSe:FUNCtion:ON 'XTIMe:VOLTage:SUM 1,2'
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).
