0.1MHz~2400MHz PLJ-9VFD-A frequency counter frequency measurement module 0.1MHz~2400MHz PLJ-9VFD-A frequency counter frequency measurement module Description: PLJ-9VFD is nine Fluorescent Display VFD (Vacuum Fluorescent Display) display shows the frequency of high cost components, mainly for the transceiver frequency display device can also be used in conventional frequency measurements. The assembly has a compact, reliable performance, visual effects, low cost and so on. Main features: ? with Microchip's PIC16F648A as the core 2.4GHz frequency meter. ? frequency reference is temperature-compensated voltage controlled crystal oscillator (2.5 ppm VC-TCXO). ? unique gate control and precise time algorithm (non-timed interrupt). ? gate (display refresh) /0.1 second time 0.01 seconds /1.0 seconds is optional. ? three single-ended input channels (low channel / high channel / Auto Channel) is optional. ? double IF design, IF value and plus / minus preset mode can be used alone, independently of each other. ? using the new Samsung nine VFD screen display, eight adjustable brightness. ? automatic zero blanking invalid, void frequency display filtering options, the last bit blanking optional. ? circuit overcurrent and overvoltage reverse polarity protection design, the whole layout is reasonable. ? two-button control, simple operation. ? the settings are saved automatically, start a direct call. Technical parameters 1. The gate time ? 0.01 S ? 0.10 S ?1.0 seconds 2. Measure the channel (channel level are high impedance) ? low channel Measuring range: 0.1 MHz ~ 60 MHz Accuracy: ± 100Hz (0.01 1s gate time) ± 10Hz (0.1 seconds when the gate) ± 1Hz (1.0 seconds when the gate) Channel Sensitivity: 0.1 MHz ~ 10 MHz: better 60mVPP 10 MHz ~ 60 MHz: better 60mVPP 60 MHz ~ 75 MHz: Untested ? high channel (64 division) Measuring range: 20 MHz ~ 2.4 GHz Accuracy: ± 6400Hz (0.01 seconds when the gate) ± 640Hz (0.1 1s gate time) ± 64Hz (1.0 1s gate time) Channel Sensitivity: 20 MHz ~ 30 MHz: better 100mVPP 30 MHz ~ 60 MHz: better 50mVPP 60 MHz ~ 2.4GHz: Untested ? Auto Channel According to the input signal frequency channel is automatically selected high or low channel, identifying the frequency of 60 MHz. If the input signal amplitude is greater than 60 MHz is less than when not automatically select the high channel, manually select high frequency measurement channel. 3. IF Set Independent double-IF design, IF adjust the minimum increments of 100 Hz, the mid range 0 ~ 99.9999 MHz, can be set plus or minus IF IF mode. 4. frequency reference Warming 13.000MHz 5032 package uses voltage controlled crystal oscillator (VC-TCXO), frequency stability of ± 2.5 ppm. 5. Working Voltage DC Input: DC 9V ~ 15V (with a reverse polarity and over-current protection) 6. Working current Less than 140 mA (test condition: (1)DC12V supply; (2) eight brightness) 7. Display digits Nine VFD display, shows up nine digits. 8. Display brightness Eight VFD brightness adjustable, factory default setting is maximum brightness. 9. component size Length × width × height: 120 mm × 36 mm × 20 mm 10. Quality Components 60 g (NW) 11. Onboard Interface DC IN (Power Interface): HX2.54-2P socket RF IN (signal input): HX2.54-2P socket ICSP (programming interface): 2.54-6P Pin include : 1 PC
