:OVLRegister (Overload Event Register)
(see page 658)
Query Syntax
:OVLRegister?
The :OVLRegister query returns the overload protection value stored in the
Overload Event Register (OVLR). If an overvoltage is sensed on a 50
Ω
input, the input will automatically switch to 1 M
Ω input impedance. A "1"
indicates an overload has occurred.
NOTE
You can set analog channel input impedance to 50Ω. If there are only two analog channels,
you can also set external trigger input impedance to 50
Ω.
