-The '''General Radio 1150-B Digital Frequency Meter''' was only available in Catalog S 1965.
+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 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.
