Introduction
The Aceco SC-1 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 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.
