:OVLenable (Overload Event Enable Register)
Command Syntax
:OVLenable <enable_mask>
<enable_mask> ::= 16-bit integer
The overload enable mask is an integer representing an input as described
in the following table.
The :OVLenable command sets the mask in the Overload Event Enable
Register and enables the reporting of the Overload Event Register. If an
overvoltage is sensed on a 50
to 1 M
Operation Status Register.
You can set analog channel input impedance to 50 on the 300 MHz, 500 MHz, and 1 GHz
N O T E
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 .
