General Technical Documentation

This covers technical information which is common to most if not all stations. A description of the configuration description in software is part of the stn_cfg package.

Generic Information

K-Band

Over-all block diagram of the 3-channel K-band systems.

K-Band YIG Filters

These tunable RF filters are available but not used because of their amplitude instability. A stabilized filter is being tested at MDSCC.

RF Matrix Switch

This matrix switch selects which front-end will be handled by which MMS down-converter.

HP MMS Downconverter

General purpose spectrum analyzer, surveillance receiver, and 1-26 GHz down-converter.

321.4 MHz IF Distribution Assembly

IOtech Digital Interface

This digital input/output unit is becoming obsolete and is being replaced by Agilent units. This pages are kept for reference, particularly the controlled device pin connections.

IF Matrix Switch

This 6x24 matrix switch can direct any of six IF inputs to and of 24 outputs. There is one currently at DSS-13, DSS14, and SPC-60.

VLBI Video Downconverters

This show how to use the video down-converters in the VLBI DAT to convert IF to baseband and low-pass filter it.

VLBI Science Receiver

This unit, available at all DSN Complexes, is becoming the standard spectrometer.
