DETECTOR PENTRU SISTEME DE INTERCEPTIE ( MICROFOANE )

Introduction
  
  The Aceco SC-1 hand-held radio frequency counter and detector is compact, truly pocket-sized, versatile test instrument designed for scan and detecting micro transmitters also any analog digital, on/off keying signal on frequencies between 30 MHz and 2.8 GHz. Supplied as a complete with internal NiCd pack, AC wall charger and 7 section telescopic antenna.

  Controls
  
  1. SQL Knob - This knob turns the RF counter on and tunes the squelch up or down to set the signal strength for reception.
  2. Range Switch - This should be switched to the 1 GHz position for frequencies between 30 MHz and 0.8 GHz and switched to the 2.8 GHz position for frequencies between 500 MHz and 2.8 GHz.
  3. Hold Button - This holds the current display and stops the counter from counting.
  4. Calibration - The 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.
