Compact, truly pocket-sized, universal test instrument designed to measure any digital, on/off analog signal or keying on frequencies from 30 MHz and 2.8 GHz

Compact, truly hand-sized, universal test device designed to measure any digital, on/off analog signal or keying at frequencies from 30 MHz and 2.8 GHz. Supplied as a complete set with an internal NiCd pack, AC wall charger and 7 section telescopic antenna.

Feature

• 7-way with liquid crystals

• Frequencies for digital counter, on/off keying and analog signals with a minimum pulse width of 250 uS.

• Ultra sensitive synchronous detector - 16 point bargraphs show RF signal (-35dB to 0 dBm)

• Two series positions - 1 GHz positions for frequencies from 30 MHz and 1 GHz and 2.8 GHz positions for 500 MHz and 2.8 GHz frequencies.

• Squelch input signal adjustment

• Hold switch to lock the display

• Low battery indicator

• Vibration

• Low power consumption (average 5 hours battery life)

• Comes with NiCd pack, AC wall charger and telescopic antennas (143 MHz to 460 MHz)

Specifications

• Impedance: 50 ohms (Socket BNC), 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

• Time base: less than 1 ppm at room temperature

• Weight: 210 g

• Size: 80 mm x 68 mm x 31 mm deep

• Subject: Pressed anodised aluminium with black finish

• Batteries: internal 4 x AA 600 mAh NiCd pack

• Power supply: 9 VDC 300 mA

Controls

• SQL Knob – This knob turns against on and the melody to silence up or down to set the signal strength for reception.

• Switch range - This should be switched to 1 GHz at frequencies between 30 MHz and 0.8 GHz and switched to 2.8 GHz for frequencies of 500 MHz and 2.8 GHz.

• Hold Button - This applies the current display and stops the counter from counting.

• Calibration - Calibration adjustment opening is located on the front panel of the counter. This allows access to the lawn capacitor, which provides around 10 range of ppm adjustments to the time base oscillator. This is not usually necessary, but to read the signal about a known frequency, such as adjusting the lawns for the correct display frequency. If you calibrate to 4.1943 MHz or higher, then the counter will be more accurate.
