Bug Detector with Frequency Counter
RF Counter
Hand Held Analog Digital RF Counter Frequency Detector
This item is the latest technology in hand-held radio frequency detection. It uses the latest micro processor circuitry for the most accurate detection of wireless transmission. Built-in signal strength meter and sensitivity control. LCD screen displays actual frequency that is being detected. This RF Counter Bug Detector is loaded with features and even comes with 2 different antennas for more accurate detection. Full detection range from 1 MHz to 2.8 GHz.
A compact, truly pocket-sized, versatile test instrument designed for measuring any digital, on/off keying or analog signal on frequencies between 30 MHz and 2.8 GHz. Supplied as a complete set with internal NiCd pack, AC wall charger and 7 section telescopic antenna.
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.

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.
