CH<x>:TERmination
Description
This command sets the connected/disconnected status of a 50 Ù resis-
tor, which may be connected between the specified channel’s coupled
input and instrument ground. The channel is specified by x. The value
of x can range from 1 through 4 for four--channel instruments or 1
through 2 for two--channel instruments. There is also a corresponding
query that requests the termination parameter and translates this enu-
meration into one of the two float values. This command is equivalent
to selecting Termination from the Vertical menu or toggling between
termination values from the VERTICAL area of the front panel.

Syntax 1
CH<x>:TERmination <NR3>
Syntax 2
CH<x>:TERmination?
Argument
H <NR3>
This specifies the channel input resistance, which can be specified as
50 or 1,000,000 Ù.
Example 1
CH4:TERmination 50.0E+0
This command establishes 50 Ù impedance on channel 1.
Example 2
CH2:TERmination?
This query might return
:CH2:TERMINATION 50.0E+0
indicating that channel 2 is set to 50 Ù impedance.
