10 :CHANnel<n> Commands
:CHANnel<n>:PROTection
(see page 1138)
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 267) 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>
