24GHz Professional Mobile Spectrum Analyzer

Product number: PKI 4280

This PKI 4280 portable 24GHz Professional Mobile Spectrum Analyzer with a sweep speed of 10kHz aug 24GHz in less than one second is designed to detect unknown, illegal, interfering and anomalous transmissions in a frequency range of 10kHz – 24GHz. This makes the PKI 4280 24GHz Professional Mobile Spectrum Analyzer eavesdropping detection possible, just like microwave links or any communication system. A wide variety of modulation types such as FM wideband, FM narrowband, AM wideband, AM narrowband, subcarrier, single sideband, NTSC, PAL, SECAM video formats, wideband AM or wideband FM demodulation bandwidth are detected.
The highly modern PKI technology makes this spectrum analyser a globally leading model that no government agency should be without.

• Sound in 800kHz, 200kHz, 12.5kHz, 6.25kHz, 2kHz.
• Video in 12.75MHz, 6.375MHz.

The built-in antennas and analysis software facilitate deployment and allow for rapid acquisition and comparison of spectral data from multiple locations.

The multi-purpose probe is inserted into the auxiliary port for acquisition and gives the following options:
• Carrier current signals between 10kHz – 150MHz
• Coax (F connector) for single-ended and general-purpose measurements (75 ohm cable connector included) with frequency range from 5MHz to 2GHz, CATV for in-line measurements of cable TV systems
• VLF magnetic loop for analysing activity in the low-frequency range from 20kHz – 20MHz
• IR (700 – 1100nm) for detection of infrared line-of-sight signals from 50kHz to 1.2GHz 5VL (450 – 1100nm) for detection of visible light transmissions from 50kHz to 1.2GHz

The directional antenna makes it easier to find transmitters. The directional antenna is held in the hand or can be clamped to the antennas. The range is 1.5GHz to 8GHz with a gain of 5dB.
