ISO-Channel Eliminates Ground Loops and Increases
Common-Mode Rejection
ISO-Channel technology eliminates ground loop problems by using a differential, isolated,
floating front-end. As you can see in
system ground.
To measure floating signal sources, ISO-Channel technology uses differential analog input
signals, a 24-bit Delta-Sigma A/D converter for each channel, and channel-to-channel
isolation, as shown in
