Channels 23–25 in this schematic

refer to the designations used for

control and not actual available channels.

For more information, refer to the

ROUTe:MULTiple command section

in the Model 2700, 2701, or 2750 User’s Manual.

Channels 24 and 25 can be individually

controlled using ROUTe:MULTiple if the

module is not to be connected to the

internal DMM.

20-channel, Differential Multiplexer Module

with Automatic CJC, Screw Terminals, and up to 50MHz Bandwidth

The Model 7700 plug-in module offers 20 chan-

nels of 2-pole or 10 channels of 4-pole multi-

plexer switching that can be configured as two

independent banks of multiplexers. There are

two additional protected channels for current

measurements. Automatic CJC is provided so

that no other accessories are required to make

thermocouple temperature measurements. In

addition, the Model 7700 contains latching

electromechanical relays that enable signal

bandwidths of up to 50MHz. The Model 7700

is ideal for RTD, thermistor, and thermocouple

temperature applications.
