Applications
Channel Select Assemblies of this type were used in ground-based satellite communication (SATCOM) earth station equipment and microwave link systems, where an operator or remote controller needs to switch between discrete RF frequency channels or waveguide paths. Varian's Microwave Equipment Division was a major supplier of microwave and satellite communication hardware from the 1970s through the 1990s, producing traveling-wave tube amplifiers (TWTAs), power supplies, and associated switching and control assemblies for both commercial and government earth station applications. This type of controller would typically interface with an RF switching matrix or frequency converter bank, allowing the system to step through predefined channel assignments via front-panel pushbuttons in Local mode or under command from a remote controller or supervisory system in Remote or Auxiliary mode. The dual LED displays give the operator a clear readout of both the active channel and the in-progress selection at all times. Equipment of this generation dates from the 1980s to early 1990s and is commonly sought for maintaining or repairing legacy earth station infrastructure.
This Varian VJW1455B1 Channel Select Assembly (P/N 01014521-00) has been inspected and is in good condition. The front panel shows light surface wear consistent with normal use — the pushbuttons, LED displays, and red power switch are all intact and undamaged. The rear D-sub connectors (J2 through J6) and the IEC AC power inlet appear clean with no bent pins or damage visible. The aluminum chassis has minor scuffs and handling marks typical of bench equipment but no dents or cracks. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
