:OVLRegister (Overload Event Register)
(see page 1610)
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 on the 300 MHz, 500 MHz, and 1 GHz
bandwidth oscilloscope models. On these same bandwidth models, if there are only two
analog channels, you can also set external trigger input impedance to 50
Ω.
