Detailed Product Description

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:

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.
