:OVLenable (Overload Event Enable Register)

Command Syntax

N O T E

(see page 530)

: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.

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.
