WWH-1pc HZ210 frequency meter high frequency 2MHz-2GHz / low frequency 0-8MHz + counter

I. Overview:  HZ210 is a compact frequency meter can measure low-frequency and high-frequency signals.   The module is easy to use, by key operation, select a different testing methods.   Second, the product application: ? measuring the pulse frequency; ? measure radio frequencies;       Third, the technical parameters: No. Item Parameter Unit Remark 1 measuring low frequency range 1Hz ~ 8MHz Hz 2 low-voltage measurement range of +/- 0.7V ~ +/- 15V 3 measuring low frequency of 1 Hz differentiate 4 measuring high frequency range 2MHz ~ 2.0GHzHz 5 high-frequency voltage measuring range +/- 100mV ~ +/- 5V 6 high-frequency measurement differentiate degrees 1KHZ Hz 7 7 ~ 12 VDC operating voltage   Note: The low frequency signal is not detected AC signal at the input signal terminal series about a 1OuF capacitance measurements.       Measuring the low-frequency signal is a DC-coupled to your own series AC-coupling capacitance measurement.     Fourth, the interface specification and related operations P1 connector (power supply)    VDD: positive power supply (7 ~ 12V)    GND: power supply negative   P2 Interface (output signal)    FX: measuring low frequency input signal.    RF: measuring the high-frequency input signal.    GND: negative power.     Fourth, Key Description   FUN: Select (high / low frequency) measurement   MODE: Select the display units / counters.     4.1, low frequency measurement Interface display font: The first line of "1.FX = 8MHZ" The second line "00000000Hz" Key operation: MODE: Select the display units.   4.2, high-frequency measurements Interface display font: The first line of "2.RF = 20.0GHz" The second line "0000.000MHz" Key operation:     4.3 cumulative counter (maximum frequency measurement 100KHz) Interface display font: The first line of "3.FX = Counter" The second line "00000000n" Key operation: MODE: the counter is cleared.
