Introduction:

Smart RF signal detector hand-held radio frequency counter is 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 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 bar graph 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 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.
