{{Catalog History}} | |||
}} | |||
The {{Title|General Radio 1124 Time Signal Receiver}} was available in {{catalog T}} only. It is a Time Broadcast Receiver System consisting of a modified [[tekwiki:RM564|Tektronix RM564 storage oscilloscope mainframe]] with a [[tekwiki:2B67|Tektronix 2B67 time base]], and a GenRad-made receiver plug-in. Antenna connections to the receiver are routed through the rear of the modified oscilloscope mainframe. | |||
The instrument came with five receiver circuit boards for RF frequencies of 2.5, 3.33, 5.0, 7.335, and 10 MHz, respectively, any two of which could be installed in the receiver module at the same time, in addition to a Loran-C (100 kHz) receiver board and an IF amplifier board that occupy two more sockets. | |||
The 1124 is designed to work with a [[1123-A|GR 1123-A Digital Syncronometer]] (a time comparator with a 6-digit Nixie clock display) and a [[1115-B|GR 1115-B 5 MHz/1 MHz/100 kHz Standard Frequency Oscillator]] based on an OCXO. | |||
The oscilloscope is used to align reference pulses produced by the 1123 with the received signal. | |||
