FLUKE 1952B

The 1952B Universal Counter-Timer measures frequency (DC-80 MHz), frequency ratio, time interval, period, period averages, and a gateable totalize with 7-digit accuracy. Standard with two input channels (complete with X1 and X10 attenuators), AC and DC coupling, and individual trigger controls including ?slope, variable and preset trigger level controls and trigger status indicator lights. A marker output enables the operator to set the start and stop triggering points accurately. Input sensitivity is 50 mV (DC to 50MHz), 75 mV rms (50 to 80MHz). 10MHz time base with aging
