Voltage measurement connections

You can perform single or dual channel voltage

measurements. The dual channel feature of the 2182A

allows you to make comparison measurements in a

test circuit.

The following figure shows typical connections to measure a

DUT using a single channel.

The following figure shows typical connections to make

comparison measurements of two devices in a test circuit.

For this measurement configuration, there is no voltage

differential between the two measurement channels.

Channel 2 HI is connected directly to Channel 1 LO.
