Handheld Spectrum Analyzer for Distributed Antenna Systems
To support the growth of distributed antenna systems (DAS), SAF Tehnika has developed another product in the company’s Spectrum Compact portfolio of spectrum analyzers: the J0SSAP33 covers 300 MHz to 3 GHz and features instant-on functionality, an ultra-compact form factor, lightweight and an intuitive graphical interface.
The analyzer has switchable internal attenuation up to 30 dB and handles a maximum input power of +27 dBm, allowing it to work close to the transmitter. The resolution bandwidth (RBW) is adjustable from 10 to 300 kHz, which provides the flexibility to quickly check the spectrum with a wider RBW, then closely examine a narrowband signal. The receiver’s high sensitivity—a noise floor of −128 dBm at 10 kHz RBW—enables very weak signals to be observed.
Housed in a rugged anodized aluminum case, the J0SSAP33 does not require an external controller, and 8 GB of internal memory provides the storage needed for spectrum scans during space mapping. The built-in recording feature can save hundreds of hours of data for deeper analysis and reporting using SAF’s Spectrum Manager PC software. Spectrum Manager can also be used to run the spectrum analyzer remotely from a PC.
Designed to be the ultimate tool for easy physical layer investigation, the J0SSAP33 spectrum analyzer is built for the rigors of the field. The lightweight and handheld design make it easy to perform walk tests. Experienced RF engineers will appreciate the efficiency gaining insight and quickly getting accurate measurements and data, while an RF novice can be trained to be proficient using the analyzer in a few hours.
The J0SSAP33 is the latest addition to SAF Tehnika’s handheld spectrum analyzer family, joining seven models covering 2 to 40, 56 to 67 and 70 to 87 GHz and extending low frequency coverage to 300 MHz.
