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 0dBm)
* Two range positions - the 1 GHz position for frequencies between 30 MHz and 0.8 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
* Low power consumption (Average 5 hour battery life)

Controls

* SQL Knob - This knob turns the RF counter on and 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 30 MHz and 0.8 GHz and
   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 - 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.

Warranty

* EZ SPY Cam guarantee the RF counter and its accessories for one year against defects in manufacture. This warranty does not cover items that have been modified, subject to unauthorized repairs, misuse or abuse. This warranty does not cover damage caused by excessive power levels applied to the signal input.

* Warning: Never attempt any kind of connection between the RF counter and a transmitter.

Hints & Tips

  • NiCd Operation
    This RF counter can operate for up to six hours from its fully charged NiCd batteries. They are charged when the unit is plugged into the supplied AC/DC adapter. Full recharge will occur over 12 to 16 hours. Before recharging the batteries you should be deep cycled occasionally by allowing them to completely discharge to maintain maximum battery capacity. The NiCd batteries should last for several years. However, it is a good idea to check them every twelve months for signs of corrosion or leakage. Always replace the whole set if any one cell fails.
  • Signal Input
    When using the RF counter with an antenna for signal pick up, random frequencies may appear on the display. This is quite normal and is caused by the high gain of the receiver circuits, which amplify noise in the absence of a strong readable signal. Never get the unit too close to a transmitter as internal damage will result.
  • Antenna Selection
    The supplied telescopic antenna is best for general purpose use. This is because its length can be adjusted to suit the frequency required. Usually you will want a shorter antenna for UHF and a fully extended one for VHF / HF.
  • Reception Distance From Transmitter
    The distance from which you will be able to receive frequencies will depend upon the type and location of the transmitting antenna, transmitter output power and the frequency in use.
