SKU: AL2174 Category:

The Apogee Labs AL2174 Interfacer is a wide band, Automatic Gain Control (AGC) analog signal buffer amplifier system containing one or more IOC802 module(s). A typical use of the IOC802 is as an automatic gain control for telemetry receiver outputs that are input to recorders.

The AL2174 chassis houses up to seven (7) dualslot IOC802 modules, each containing one signal input and four (4) buffered outputs. Front-panel access is provided for test points, toggle switches and trimmers. Each IOC802 module is a self-contained wideband AGC analog signal buffer amplifier. Front panel controls for each channel include an AGC mode selector (Fast, Slow attack / Manual), Offset control, and a Gain control. A Test Point connector provides an accurate buffered signal output.

The design of the 2174 and its complement of IOC802 modules stress the concepts of signal integrity, channel isolation and low noise contribution. So as to minimize the possibility of signal contamination, there is no interconnection between modules on the backplane of the chassis.
