Precision Frequency Counter (0.01Hz - 2.4GHz)

Brief Description

 

This frequency counter measures signals over a wide range from 0.01 Hz to 2.4 GHz. The gate time is continuously varying from 100ms to 10s. The maximum power consumption is only 5W.

 

The instrument provides high performance stability and function at low cost. The counter can measure frequency, period and equal-precision. It is also featured with 3 step function selection, work state, unit and eight-digit LED display.

 

All functions in this frequency counter depend on a single CPU. A crystal-controlled temperature circuit provides a constant compensation for temperature change, thus reducing measurement errors typically caused by temperature drift. The Channel B (CH. B) input has an attenuator (x1, x20), AC/DC coupling for a low-pass filter.

 

Features

  • With 3 steps function selection: work state, unit & 8-digit LED display

  • Frequency measurement from 0.01 Hz to 2.4 GHz

  • Cyclic measuring range from 0.5 ms to 10 s

  • With attenuation of 20 dB and input impedance of 1 MO

  • With frequency, period and equal-precision measurement

  • Quality Management System Conformity with ISO9001:2000

  • Maximum power consumption is only 5W

  • Safe to operate

  • Conforms with European Directive health & safety standards
