FEATURES
  • 7 digit Liquid Crystal Display
  • Frequency counter for digital, on/off keying and analog signals
    with a minimum pulse width of 250 uS
  • Ultra sensitive synchronous detector - 16 section bargraph to
    show RF signal strength (-35dBm to 0 dBm)
  • Two range positions - the 1 GHz position for frequencies between
    30 MHz and 1 GHz and the 2,8 GHz position for frequencies
    between 500 MHz and 2,8 GHz
  • Squelch adjustment for input signals
  • Hold switch to lock display
  • Low battery indicator
  • Vibrating alert
  • Low power consumption (Average 5 hour battery life)
  • Supplied with NiCd pack, AC wall charger and telescopic antenna
    (143 MHz to 460 MHz)
CONTROLS
 
  • SQL KNOB - This knob turns the RF counter on the tunes the squelch up or down to set the signal strength for reception.
  • RANGE SWITCH - this should be switched to the 1 GHz position for frequencies between 30MHz and 0.8GHz, switched to the 2.8 GHZ position for frequencies between 500 MHz and 2.8 GHz.
  • HOLD BUTTON - This holds the current display and stops the counter from counting.
  • CALIBRATION - This calibration adjustment opening is located on the front panel of the counter. This allows access to the trimmer capacitor that provides about a 10 PPM adjustment range of the time base oscillator. This is not usually necessary but to do so read a signal of a known frequency before adjusting the trimmer for correct frequency display. If you calibrate at 4.1943 MHz or above then the counter will be more accurate.
  • VIBRATION Switch - This switch selects the tone or vibration alert output.
