10 :CHANnel<n> Commands
:CHANnel<n>:PROTection
(see page 792)
Command Syntax
:CHANnel<n>:PROTection[:CLEar]
<n> ::= 1 to (# analog channels) in NR1 format| 4}
With the 2000 X-Series oscilloscopes, the analog channel input impedance is
always 1 M
Ω, so automatic overvoltage protection is not necessary (as it is for
channels with 50
Ω input impedance). There are no protection settings to clear, so
the :CHANnel<n>:PROTection[:CLEar] command does nothing.
Query Syntax
:CHANnel<n>:PROTection?
The :CHANnel<n>:PROTection query always returns NORM (normal).
Return Format
NORM<NL>
