Saelig recently introduced the PX Series of real-time spectrum analyzers, offering a combination of size, performance, and cost. The three models in the series are the PXN-400, which operates from 9 kHz to 40 GHz; the 9-kHz to 20-GHz PXE-200; and the 9-kHz to 9.5-GHz PXE-90.
With a superheterodyne receiver design and multi-segment preselected filtering, they can perform RF measurements and analysis suitable for 5G and emerging 6G technologies in a robust, 3.3-lb. instrument measuring 10.2 x 7.0 x 2.0 in., with a 10.1-in. multitouch screen.
With an analytical bandwidth of 100 MHz and a spectrum scanning rate up to 900 GHz/s (RBW ≥ 300 kHz), PX Spectrum Analyzers provide standard spectrum sweep, IQ streaming, zero span and real-time analysis working modes, as well as optional digital demodulation and pulse signal measurement.
Equipped with preamplifiers to improve dynamic range and phase-noise level, they have a display average noise level as low as –168 dBm/Hz and phase noise as low as –120 dBc/Hz at 1 GHz frequency offset at 10 kHz. The FFT engine is implemented in an FPGA, and the analyzers support frame compression and trace detection, with no missing samples between FFT frames. USB and HDMI interfaces are included for the PC interface and external displays.
More Features of the PX Real-Time Spectrum Analyzers
Other features include a standard spectrum mode with a standard spectrogram, waterfall graph, probability density graph, phase noise, and other measurement graphs. They also offer measurement functions such as channel power, adjacent channel suppression, occupied bandwidth, XdB bandwidth, phase noise and IM3, peak table, and frequency tracking.
An IQ streaming mode provides time domain and spectrum view of IQ waveform, DDC and AM/FM demodulation function, modulation depth, and modulation frequency offset. There's also a power-detection mode (Zero Span), with power time diagram and scaling, timing trigger, level trigger, and other triggers.
The real-time spectrum-analysis mode offers spectrum, probability density graph, waterfall graph, and other measurement graphs, with timing trigger, level trigger, and other triggers. And a digital demodulation mode option provides digital demodulation, including AM, FM, PM, CW, LSB, USB, ASK, 2FSK, 4FSK, BPSK, QPSK, 8PSK, 16QAM, and 64QAM.
There's also a pulse signal measurement option for automatic pulse signal measurement that includes pulse width, ripple, rise time, fall time, rise edge, fall edge, PRI and duty cycle. An open API feature enables customers to customize and create their own systems based on this platform.
