The General Radio 1150-B Digital Frequency Meter, a general-purpose frequency meter and event counter, was only available in Catalog S (1965). It is an improvement on the 1150-A with higher frequency range and trigger control.
The display consists of five "Numerik" incandescent readouts (see IND-0300 and IND-1801 for details). It is interesting to note that if a lamp fails, the counter will stop at that digit because the lamp is part of the counting circuit.
Specifications
- Frequency Range: 10 Hz to 400 kHz
