INPut[<port>][:STATe]

Parameters

Parameter	Parameter		Range of	Default
Name	Type		Values	Units

port	numeric		1234	none

impedance	numeric		50751.0E61MOHM	Ohms
			MINimumMAXimum

Input ports 1 and 2		: MINimum selects 50Ω; MAXimum selects
75Ω.		: MINimum selects 1 MΩ; MAXimum selects
Input ports 3 and 4		: MINimum selects 1 MΩ; MAXimum selects
1 MΩ.

Comments ∙ Executable when initiated: Yes

∙Coupled Command: No

∙Changing the input impedance while the digitizer is taking readings (initiated) may cause unexpected reading values due to relay settling during the transition.

∙Related commands: SENSe:FUNCtion "VOLTage <port>"

∙*RST Condition: INPut12:IMPedance 50 OHM, INPut34:IMPedance 1 MOHM

.

Example Setting 75 Ω input impedance

INP:IMP 75 OHM

Set 75Ω impedance (defaults to input 1)

[:STATe]

INPut[<port>][:STATe] <mode> connects/disconnects the input ports to/from the measurement signal path. All ports have a special relay which is used to isolate the input from the signal path, regardless of whether the sensor channel is currently connected to that port or not.
