The RVP901 IFDR module is typically placed where a traditional LOG receiver would be
installed.
The module can be mounted on edge with the 26.8 cm x 4.8 cm (10.5 in x .9 in) surface flush
to the back of the receiver cabinet with 17.6 cm (6.9 in) protrusion into the cabinet.
The RVP901 IFDR is packaged in a tight metal enclosure for maximum noise immunity.

4.2.1 Upgrading IF Receiver with RVP901 IFDR
The RVP901 IFDR replaces the IF receiver components in a traditional analog receiver
system:
• AFC circuit
• AGC or IAGC circuit
• COHO (on magnetron systems)
• Band pass
filters
• Line drivers for base band video
• LOG receiver
• QuadpPhase detector
Removing old components can be time consuming. Many customers choose to bypass them
and leave them in place.
In some cases, other receiver
modifications are required to match RVP901 IFDR signal input
specifications. For example, IF attenuators or an IF amplifier may be required.
Read the document and red-line your system schematics to
reflect any changes to the
receiver.
If you are upgrading an older system, consider purchasing a new STALO to improve
Doppler performance.
