Fluke 1910A
Frequency Counter
Description
This unit measures Frequency, Period, and Totalize…quickly and easily.
In the Frequency Mode the range is 5Hz to 125MHz with ranges of resolution of 0.1Hz, 1.0Hz, 10Hz and 100Hz.
Period Mode range is 5Hz to 2MHz.
The input impedance is 1M½ shunted by less than 30pF, AC coupled.
The sensitivity is 15mV rms at 5Hz to 100MHz and 25mV rms at 100MHz to 125MHz.
Also features a front-panel attenuator switch which is provided to decrease sensitivity by a factor of 10.
It's input is provided for external time base (10MHz at 300mV rms or greater into ³1k½).
Display is a 7-digit LED with the number of units used and an overflow indicator.
