Description: Professional RF counter Aceco SC-1 plus
SC-1PLUS 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
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
