Features:
Nine converters in one module
Coaxial in, Triaxial out
50 ohms in, 75 ohms out
Adustable gain and DC offset
Module Description
The Model 12740 coaxial/triaxial converter module consists of nine coaxial
to triaxial unity gain analog amplifiers. All converters have a 50 ohm
input and 75 ohm output impedance and are designed to be used in the DC-80MHz
range with a 75 ohm load.
The module requires a power input of ±12VDC at 400mA which is supplied
through the DB-25P type power connector on the end of the module. The module
is designed to be mounted within Model 12116 chassis assembly.
Signal connection is provided by standard BNC/Triaxial type female connectors.
The output connectors are located next to the input connectors. Each amplifier
has its own gain and offset adjustment.
The vented aluminum housing provides heat sinking to the black anodized
covers. Forced air cooling is recommended.
