Description: Use 8 bit Microchip PIC16F876A,up to 1.1GHz. Gate time;0.01 seconds;0.1 seconds;1.0 seconds. Measuring channels ( high and low channels are high impedance ). Low channel: Measuring range : 0.1MHz ~ 70MHz;Measurement accuracy:+/- 100Hz ( 0.01 seconds gate );+/- 10Hz ( 0.1 seconds gate );+/- 1Hz ( 1.0 seconds gate ). IF settings: The minimum frequency is adjustable in steps of 100 Hz, frequency range 0 ~ 999.9999 MHz, can be set to plus or minus IF mode Sensitivity:0.1MHz ~ 10MHz: better than 50mVPP;10MHz ~ 60MHz: superior to 50mVPP;60MHz ~ 75MHz: not tested. High channel frequency (64 points );Measuring range : 10MHz ~ 1.1GHz Specification: Material: PCB Measurement Accuracy : +/- 6400Hz (0.01 seconds gate ) +/- 640Hz ( 0.1 seconds gate ) +/- 64Hz ( 1.0 seconds gate ) High channel sensitivity : 10MHz ~ 30MHz: better than 100mVPP 30MHz ~ 60MHz: superior to 50mVPP 60MHz ~ 1.1GHz: not tested Automatic channel is automatically selected based on the frequency of the input signal level of channel Crystal measuring channel: Measuring range : 1 MHz ~ 50 MHz ( the most low-end and highest end untested ) Frequency reference: 5032 package 13.000 MHz Warming voltage controlled crystal oscillator ( VC - TCXO) , frequency stability is +/- 2.5 ppm working voltage: DC input: DC 9V ~ 12V working current: The backlight is enabled: Less than or equal to 75 mA backlight disabling: less than equal 55 mA Display: maximum of 9 digit display Length * width * height: 92mm × 37mm × 27mm/3.62 x 1.46 x 1.06 inch Board interface: RF INPUT (measuring signal input): XH2.54-2P curved needle square socket ICSP INPUT (MCU interface): XH2.54-6P curved needle square socket ECL INPUT (external clock input): XH2.54-2P curved needle square socket POWER INPUT (Power Interface): ? with 3.5mm socket (DC is negative) The XH2.54-2P curved needle square socket Package Includes: 1 Piece of Frequency Counter
