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.
Impedance: 50 Ohms (BNC Socket) VSWR less than 2:1
Frequency range: 30 MHz – 2.8 GHz
Sensitivity: less than 5 mV
Max. input: 15 dBm
Resolution: 10 KHz for digital signals or On/Off Keying & 1 KHz for Analog Signals
Timebase: Less than 1 PPM at room temperature
Weight: 210 g
Size: 80 mm high x 68 mm wide x 31 mm deep
Case: Stamped aluminum with black anodized finish
Battery: Internal 4 x AA 600 mAH NiCd pack
Power: 9 VDC 300 mA
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)
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.
