Measuring Devices -2 Pieces 1000MHz 6LED \u0026 8LED RF Counter Frequency Counter Cymometer Meter Green Highlights Generic Brand 2 Pieces 1000MHz 6LED \u0026 8LED RF Counter Frequency Counter Cymometer Meter Green Description: 8LED: With PIC16F648A from Microchip, 2.4 GHz frequency counter. Using a temperature-compensated voltage-crystal oscillator (2.5 ppm VC-TCXO). Unique gate control and precise timing algorithm (untimed 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 preset separately. Using eight 0.56 inch high brightness digital display, eight brightness adjustable. Circuit is simple and reasonable structure, two-button control, simple operation. Parameters are automatically saved, start directly call. 1. Gate time: 0.01S 0.10S 1.0S 2. Measurement channels (channels are low impedance): low channel Measurement range: 0.1MHz~1000MHz Accuracy: 100Hz ( gate time 0.01 1s) 10 Hz (0.1 seconds when gate) 1 Hz (1.0 seconds when the gate) Specification: 6LED: Master by the United States Microchip (Microchip) PIC16F648A as the counter core of 65MHz frequency. Japan KDS frequency reference temperature controlled crystal oscillator ( 2.5 ppm VC-TCXO) Unique gate control and precise time algorithm (non-timer interrupt) Gate (display refresh) time 0.64 seconds , real-time display frequency value. 10Hz/100Hz frequency measurement accuracy (right digital) is optional. Dual IF design, IF value and plus/minus preset mode can be used alone, independently of each other. Display driver with special LED display chip, high-brightness digital tube, less foreign interference. ARK six .56 inch using digital display, zero invalid automatic blanking, eight adjustable brightness. Circuit is simple and reasonable structure, two-button control, simple operation. The parameters are automatically saved, the start is called directly. Specification: 1. The gate time (gate time) 0.64 seconds 2. Measure the channel (measurement channels) Input impedance (Impedance): high resistance Measurement range: 1 MHz to 1000 MHz Accuracy: 100 Hz / 1000 Hz Sensitivity: HM8134-2 test data (for reference only) Test frequency (MHz) 5 10 30 60 100 150 200 300 450 Sensitivity (mV RMS) 50 40 20 20 30 30 30 40 60 Test frequency (MHz) 500 550 600 700 800 900 1000 1100 1200 Sensitivity (mV RMS) 80 90 90 120 150 180 230 360 41 Package includes: 1 piece of 6LED signal frequency meter 1 piece of 8LED signal frequency meter
