:CHANnel<n>:PROTection

(see page 530)

Command Syntax :CHANnel<n>:PROTection[:CLEar]

<n> ::= {1 2 3 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 MΩ. The :CHANnel<n>:PROTection[:CLEar] command is used to clear (reset) the overload protection. It allows the channel to be used again in 50Ω mode after the signal that caused the overload has been removed from the channel input. Reset the analog channel input impedance to 50Ω (see ":CHANnel<n>:IMPedance" on page 148) 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>
