:OVLenable (Overload Event Enable Register)

(see page 530)
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 50Ω input, the input will automatically switch
to 1 MΩ input impedance. If enabled, such an event will set bit 11 in the
Operation Status Register.
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 50Ω.
