Saelig Co. Inc. has introduced the Harogic PXN Series Handheld Real-time Spectrum Analyzers, which deliver RF performance equivalent to benchtop instruments. Covering frequencies up to 9GHz, these instruments offer a standard real-time analysis bandwidth of 50MHz, which can be optionally upgraded to 100MHz. The series offers phase noise of better than -110dBc/Hz at 10kHz offset (typical with 1GHz carrier) and provides typical IF and image rejection exceeding 95dBc. Combined with a Display Average Noise Level (DANL) specification of -168dBm/Hz at 1GHz (typical with preamp on), the PXN Series enables signal capture and analysis in demanding environments. These specifications suit applications including wireless communications, broadcast monitoring, IoT development, and RF troubleshooting.

The series includes three models: PXN-45 (9kHz to 4.5GHz), PXN-60 (9kHz to 6GHz), and PXN-90 (9kHz to 9GHz), all sharing the same portable form factor. This series adopts a superheterodyne receiver architecture, with up to 14 preselector filters. Weighing 1.5kg, the design enables deployment across laboratory and field environments. The PXN series comes standard with a measurement suite including Channel Power, Occupied Bandwidth (OBW), and X dB Bandwidth. 

Capabilities such as Harmonic Analysis, AM/FM Demodulation, and automated Phase Noise measurements are integrated for signal characterization. The user interface paired with a 10.1” display supports measurement operation in lab or field use. AM/FM analog demodulation is included as a standard feature, allowing users to listen to and analyze modulated signals on the instrument itself. Optional software packages such as basic vector modulation analysis and pulse analysis are available.

Key Features include:

• High-performance superhet receiver
• 14 preselector filter bands
• Frequency range: 9kHz to 4.5/6/9GHz
• Full-band preamplifier as standard
• 1 GHz DANL: -168 dBm/Hz
• 1 GHz phase noise: <-110 dBc/Hz@10 kHz offset
• Analysis bandwidth: 50 MHz/100 MHz (opt.)
• Sweep speed: up to 1 THz/s (RBW = 250 kHz)
• IF and image rejection: >95 dBc
• Integrated GNSS, supports frequency cal via GNSS
• SCPI protocol supported for remote control
• Up to 2.5 hours battery life
• Portable 1.5kg design with a 10.1” multitouch screen

These spectrum analyzers from Harogic Technologies are now available from their technical distributor Saelig Co. Inc. Fairport, NY.
