The General Radio 1114-A Frequency Divider was introduced in Catalog Q (1961) and remained available through Catalog S (1965).

The Type 1114-A Frequency Divider is a component of the Type 1105-A Frequency-Measurement Equipment. Its designed to divide the 5 MHz input signal to produce 1Mhz output. Subsequent modules, 1114-P2 thru 1114-P5 each divide by 10. Optional modules 1114-P6 and 1114-P7 provide 400 Hz and 60 Hz outputs. The output from the modules is essentially a sine wave, although 100 kHz and 10 kHz square wave output is available from the 1114-P2 and 1114-P3 respectively. The first divider 1114-P1 is a regenerative 5:1 divider, 1114-P2 thru 1114-P5 are switching type 10:1 dividers. The plug-in modules are designed to only fit in the correct slot. A switch behind the front cover selects the driving signal from 5 MHz input signal and internal 1 Mhz or 100 kHz inputs.
