• 0 to 1200Mhz RF Signal Frequency Counter LED Display Digital Cymometer Meter Test Module eight Digits Frequency Tester Counters Features: 1 This is a 1 frequency meter, and all settings are mechanically kept and can be known as immediately upon startup 2 The frequency reference adopts a temperature compensated voltage managed crystal oscillator (2 ppm VC-TCXO) three Adopting a unique gate management method and exact time algorithm (non timed interrupt mode) four The gate (display refresh) time is optionally available at 0 seconds/0 seconds/1 seconds, and the frequency value is displayed in real-time 5 Single ended enter design, with 3 non-compulsory frequency size channels (low channel/high channel/automatic channel) 6 Dual intermediate frequency design, intermediate frequency price and addition/subtraction mode could be pre-set separately 7 It adopts an 8 digit zero high brightness digital display, with adjustable brightness levels of eight stages 8 Invalid 0 automated blanking, invalid frequency value exhibit filtering optional, and last digit blanking optionally available 9 The circuit is simple, the structure is reasonable, the dual button management is easy to operate Parameter: 1 Gate time *0 seconds *0 seconds *1 moment 2 Measurement channel (both excessive and low channels have excessive resistance) *Low channel Measurement range: zero MHz~60 MHz Measurement accuracy: ± 100Hz (at 0 moment gate) ± 10Hz (0 seconds at gate) ± 1Hz (at 1 gate) Low channel sensitivity: 0 MHz~10 MHz: greater than 60mVPP 10 MHz~60 MHz: greater than 60mVPP 60 MHz~75 MHz: untested *High channel (64 frequency division) Measurement range: 20 MHz~1 GHz Measurement accuracy: ± 6400Hz (at zero moment gate time) ± 640Hz (0 seconds at gate) ± 64Hz (at 1 gate) High channel sensitivity: 20 MHz~30 MHz: better than 100mVPP 30 MHz~60 MHz: larger than 50mVPP 60 MHz~2: untested *Automatic channel: Automatically choose high or low channels in keeping with the enter signal frequency, with a reputation frequency of 60 MHz If the amplitude of the input signal greater than 60 MHz is insufficient to automatically choose the high channel, the high channel needs to be manually chosen for frequency measurement three Intermediate frequency setting: Independent dual intermediate frequency design, with a minimal intermediate frequency adjustment step of one hundred Hz and an intermediate frequency fluctuate of 0~99 MHz It could be set so as to add or subtract intermediate frequency mode four Frequency reference: Using a 5032 kit thirteen temperature compensated voltage managed crystal oscillator (VC-TCXO) with a frequency balance of ± 2 ppm five Working voltage: DC input: DC 9V~15V (with energy polarity opposite protection) 6 Working current: most a hundred and sixty mA (test conditions: ① DC12V strength supply; ② pink digital tube; ③ 8 point brightness) 7 Display digits: Eight digit LED display, with a most reveal of 8 digits 8 Display brightness: The 8 level LED brightness would be adjusted, and the factory surroundings is the highest brightness 9 Dimensions: Length x Width x Height: one hundred twenty five mm x 25 mm x 21 mm 10 Onboard interface DC IN (power interface): HX2 socket RF IN (signal input): HX2 socket ICSP (Programming Interface): 2 pins Package include: 1* module 2 *rays
