A37 Sequence Controller

The A37 Sequence Controller assembly contains the switches which cause an HP/Agilent 8922B to function like an HP/Agilent 8922B instead of an HP/Agilent 8922A. Activating the switches causes the Clock, Data, Pulse Modulation, and Frequency Hop data to be generated using the HP/Agilent 8922B modules.

The 270.833 kHz clock and data signals, which are normally routed from the front panel, are now received from the A36 FIFO/GPIO assembly with the clock and data all properly synchronized. The pulse modulation and frequency hop information from the external computer is stored in the A37 Sequence Controller assembly, where it is synchronized and routed to the signal generator portion of the HP/Agilent 8922B to be transmitted.

Like the A36 FIFO/GPIO assembly, the HP/Agilent 8922B software also contains a Frame Control RAM test, and a HOP RAM test, to verify the ability of the external computer to read and write to the A37 Sequence Controller assembly.
