You are bidding on a tested and working General Radio 1192 DC to 30MHz frequency counter with Nixie display. General Radio is well known for having produced some of the best electronic test equipment ever made, dating back to the dawn of radio in the 1920's. This auction is for a model 1192 frequency counter, dating to the 1960's.
General Radio Model 1521-B Graphic Level Recorder produces a permanent ink record of the level of ac voltages, at frequencies from 7 cps to 200 kc. The trace, which is proportional to the logarithm of changes in input level, and hence linear in decibels, may be plotted as a function of time, on translucent chart paper. When the recorder is set up to drive the dial of an external oscillator, it automatically plots level vs frequency, yielding a permanent record with minimum time and effort.
