:INPut:IMPedance:CH1

Description

This command gets or sets the input impedance of channel 1.

Syntax	Parameter
`:INPut<ch>:IMPedance<tr>:CH1`	{ `50[Ohm]` \| `1e6[Ohm]` }

Parameters	accepted format	allowed suffixes	possible Errors	description
<`ch`>	{ `1` \| `empty` }	`none`	`Invalid channel index`	Currently only one channel is supported. `Empty` means `1` is used as default.
<`tr`>	{ `1` \| `empty` }	`none`	`Invalid trace index`	Currently only one trace is supported. `Empty` means `1` is used as default.
{ `50[Ohm]` \| `1e6[Ohm]` }	numeric value (either `50` or `1MA`)	`Ohm`	`Settings conflict`	The termination impedance.

Syntax	Response
`:INPut<ch>:IMPedance<tr>:CH1?`	{ `50` \| `1000000` }

Parameters	accepted format	description
<`ch`>	{ `1` \| `empty` }	Currently only one channel is supported. `Empty` means `1` is used as default.
<`tr`>	{ `1` \| `empty` }	Currently only one trace is supported. `Empty` means `1` is used as default.

Response value	description
{ `50` \| `1000000` }	the termination impedance (either 50Ω or 1MΩ)

Only in certain measurement modes certain impedance values can be changed. See Allowed Changes for further details.

For presets please refer to Measurement Modes.

Set the impedance of channel 1 to 1MOhm in GainPhase measurement.
