The General Radio 1150-B Digital Frequency Meter was only available in Catalog S 1965. The Type 1150-B is a general purpose frequency meter and event counter. Its an improvment on the 1150-A with higher frequency range and trigger control. For the frequency display it uses five "Numerik" incadesant readouts. See IND-0300 also IND-1801 for details. An interesting to note that is a lamp fails the counter will stop at that digit. The lamp is part of the counting circuit.
