HANDHELD REAL-TIME PECTRUM ANALYZER
The PX series packs a punch with its handheld real-time spectrum analyzer, featuring a sleek 10.1-inch full touch screen. Weighing in at just 1.5 kg, this lightweight marvel covers a frequency range from 9 kHz to 40 GHz. With an analysis bandwidth of up to100 MHz and a sweep speed of up to 900 GHz/s, it’s a powerhouse.

PX series is capable of four working modes, including SWP (standard spectrum analysis), IQS (IQ streaming), DET (power detection analysis or zero span), and RTA (real-time analysis).
