:CHANnel<n> Commands
:CHANnel<n>:PROTection
Command Syntax
:CHANnel<n>:PROTection[:CLEar]
<n> ::= 1 to (# analog channels) in NR1 format| 4}
When the analog channel input impedance is set to 50
Ω
, the input channels are
protected against overvoltage. When an overvoltage condition is sensed, the input
impedance for the channel is automatically changed to 1 M
Ω
.
The :CHANnel<n>:PROTection[:CLEar] command is used to clear (reset) the
overload protection. It allows the channel to be used again in 50
Ω
mode after the
signal that caused the overload has been removed from the channel input.
Reset the analog channel input impedance to 50
Ω
(see
on page 288) after clearing the overvoltage
protection.
Query Syntax
:CHANnel<n>:PROTection?
The :CHANnel<n>:PROTection query returns the state of the input protection for
CHANnel<n>. If a channel input has experienced an overload, TRIP (tripped) will
be returned; otherwise NORM (normal) is returned.
Return Format
{NORM | TRIP}<NL>
