11 :CHANnel<n> Commands
:CHANnel<n>:PROTection
(see page 1610)
Command Syntax
:CHANnel<n>:PROTection[:CLEar]
<n> ::= 1 to (# analog channels) in NR1 format| 4}
When the analog channel input impedance is set to 50Ω, 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
":CHANnel<n>:IMPedance" on page 350) 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>
