The frequency counter is an intellective multi-function instrument with 10Hz-2400MHz frequency, including frequency measurement, pulse counting, crystal measurement and so on, and has 4 step gate time, 5-range function select and All functions depend on a single CPU. A crystal controlled temperature circuit provides constant compensation for temperature change. Thereby,reducing measurement errors typically caused by temperature drift. This instrument has the function of operation mode stored, due to this reason. After turning the power on, it can be operated by previous setting. This instrument has 3 input channel terminals CH.A.high frequency terminal 50MHz-2400MHz CH.B.low frequency terminal 10Hz-50MHz Crystal Oscillator: crystal measuring terminal Total 5 steps. No1-3 steps are for frequency, No.4 step is for counting and No.5 is for crystal oscillator No.1 step 50MHz-2400MHz,input from CH.A No.2 step 4Mhz-50MHz, input from CH.B No.3 step 10Hz-4MHz, input from CH.B Step Function Frequency Resolution 1 Frequency measurement 2400MHz-1000MHz 1KHz 100Hz 100Hz 100Hz 1000MHz-100MHz 1KHz 100Hz 10Hz 10Hz 100MHz-50MHz 1KHz 100Hz 100Hz 100Hz 2 50MHz-4MHz 100Hz 10Hz 1Hz 1Hz 3 4MHz-10Hz 10Hz 1Hz 0.1Hz 0.1Hz 4 Counting Max.counts99999999 - - - - 5 Crystaloscillator measurement 16MHz-3.5MHz 10Hz 1Hz 1Hz 1Hz Accuracy: time base deviation* frequency +/-1d 3.Progressive counting measurement resolution: +/- 1d counting frequency: 10Hz-4MHz 5 steps insert from crystal oscillator plug-board on the panel. 2.Input features:Input sensitivity for CH.A, 25m Vrms/200m Vrms Input resistance: approx. 50 ohm Input sensitivity for CH.B: No.2 range: 25m Vrms/80m Vrms No.3 range: 10m Vrms/30 Vrms Input resistance: approx.1Mohm(less than 35pF) Max short-term stability: +/-3*10^8/second long-term stability: +/-2*10^3/month temperature:+/-2* 10^3/10C-40C 8 digital LED display with frequency,counting,crystal oscillator,KHz,every range and gate time. 5.Power: breadth AC 220V/110V +/-10%; frequency; 50Hz/60Hz 10. power: AC 220/110V +/-10% Max.consumption is 5W at 50Hz/60Hz All our VC serial Frequency Counters are provided one year warrantee by us from the date you make a purchase.
