Description

The Model 619M is a low cost differential amplifier useful in test environments where high CMRR
is desired. Encore's Model 227
F/V converter can also be used in
the six-module 4015-111 rack. An
AC power supply is built into the rack, and provides the required unregulated DC voltages to operate the modules. Single- and two-module benchtop carrying cases are also offered.
