INPut Subsystem
The commands under the INPut subsystem are used to select the INPut signal source
and set the input impedance and range of the analog inputs, A and B. As indicated
in the commands, not all INPut suffixes are available for all the commands.

Reference
INPut[1|3]:IMPedance <numeric_value>
Usage:
Set input impedance of the two analog inputs, A and B.
Parameters:
Parameters for
<numeric_value>
are 150, 600, and 200000.
Units:
Ohms (termination impedance)
Query:
INP[1|3]:IMP?
returns the input impedance setting for the designated
analog input.
*RST:
Sets INP[1|3] impedance to 200000
W.
INPut[1|3]:RANGe <numeric_value>
Usage:
Used to manually select the input range of the analog inputs. Turn off Auto
Range first before setting a new input range to maintain the new manually
selected input range. If Auto remains on, it will reset the input range according
to the applied signal amplitude.
