Rf Signal Frequency Counter Tester Cymometer Frequency Meter

With Microchip PIC16F648A,2.4 GHz frequency meter.Use temperature compensated voltage-controlled crystal oscillator (2.5 ppm VC-TCXO).Unique gate control and precise time algorithm (non-timed interrupt).Gate (display refresh) time 0.01 seconds / 0.1 seconds / 1.0 seconds,real-time display frequency value.Single-ended input design,three-channel frequency measurement (low channel / high channel / Auto Channel).Dual frequency design,value and IF / down mode can be set separately.Using eight 0.56 inch high brightness digital display,eight brightness adjustable.Circuit is simple and reasonable structure,two button control,easy operation.The settings are saved automatically,call boat directly.Specification:Gate time:0.01 second0.10 second1.0 secondMeasurement range: 0.1MHz-60MHzAccuracy: 100Hz (0.01 1s gate time)10Hz (0.1 seconds gate)1Hz (1.0 seconds when the gate)Low channel sensitivity:0.1MHz-10MHz: better than 60mVPP10 MHz-60 MHz: better than 60 mVPP60 MHz-75 MHz: Not testedHigh Channel: (Divided by 64)Measurement range: 20 MHz-2.4 GHzAccuracy: 6400Hz (0.01 seconds gate)640Hz (0.1 1s gate time)64Hz (1.0 1s gate time)High channel sensitivity:20 MHz-30 MHz: better than 100 mVPP30MHz-60MHz: Better than 50mVPP60 MHz-2.4 GHz: not testedAuto Channel:Automatically selected according to the input signal frequency high or low channel channel,identify the frequency of 60 MHz.Such as when the input signal amplitude is greater than 60MHz deficit can not automatically select high channel,the channel must manually select high frequency measurement.Frequency reference:Use 5032 package 13,000 MHz Warming voltage-controlled crystal oscillator (VC-TCXO),frequency stability of 2.5 ppm.Working voltage: DC 9V-15V (with reverse polarity)Operation Current: Maximum 160 mAEight LED display,the highest display eight digits.Colour:GreenMaterial:plasticPackage Contents:1* Signal frequency counterOnly the above package content,other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.The measurement allowed error is +/- 1-3cm.
