:CHANnel<n>:DISPlay
Syntax
:CHANnel<n>:DISPlay <bool>
:CHANnel<n>:DISPlay?
Description
Turns on or off the specified analog channel; or queries the on/off status of the specified analog channel.
Parameter

Default
<n>
Discrete
{1|2|3|4}
--
<bool>
Bool
{{1|ON}|{0|OFF}}
CH1: 1|ON
CH2, CH3, CH4: 0|OFF
Return Format
The query returns 1 or 0.
:CHANnel<n>:IMPedance
Syntax
:CHANnel<n>:IMPedance <imped>
:CHANnel<n>:IMPedance?
Description
Sets or queries the input impedance of the specified anal
og channel. The default unit is Ω.
Parameter

Range
Default
<n>
Discrete
{1|2|3|4}
--
<imped>
Discrete
{OMEG|FIFTy}
OMEG
Remarks
OMEG: 1 MΩ. This indicates that the input impedance of the oscilloscope is rather high, and the
current flowing from the circuit under test to the oscilloscope can be ignored.
FIFTy: 50 Ω. This indicates that the oscilloscope shall be matched with a device whose output
impedance is 50 Ω.
Return Format
The query returns OMEG or FIFT.
:CHANnel<n>:INVert
Syntax
:CHANnel<n>:INVert <bool>
:CHANnel<n>:INVert?
Description
Turns on or off the invert display of the specified analog channel; or queries the on/off status of the invert
display of the specified analog channel.
