Real Time Spectrum Analyser RTSA7500 from BNC

Berkeley Nucleonics PC-Controlled Real Time Spectrum Analysers (RTSA)

 

The BNC Model RTSA7500 Real Time Spectrum Analyser has all the standard features of a spectrum analyzer such as frequency controls, marker functions and multi-trace functionality. It also includes a real-time trigger mode for measuring complex data signals such as Wi-Fi and LTE along with markers for tracking specific frequencies.

 

Real-time triggering is enabled by sophisticated FPGA-based digital signal processing within the RTSA7500 and enables the capture of elusive, time-varying signals across an instantaneous bandwidth of up to 100 MHz. The Model RTSA7500 is a powerful and cost-effective solution for your real time spectrum analyser needs in the lab, on the manufacturing floor or out in the field.

SpectrogramSpectrogram View
Along with the standard spectrum graph which plots Power versus Frequency the user can select the Spectrogram View. The Spectrogram View provides a 3-dimensional view of the spectrum adding the dimension of Time. Time zero is at the top of the Spectrogram view and measurements in the past scroll down. The color indicates the relative magnitude of the Power. In this case, white being the highest power. Several palettes are available to optimize for best viewing depending on the signals to be evaluated. By looking at Time, one can see the periodicity of any given signal.

 

Power Spectral Density

Power Spectral Density Display
The Power Spectral Density Display is commonly called the Persistence Display. Both names give a partial description of what the display does. The color is an indication of how dense or how often the signal is present at the respective power level. In this case yellow represents the level the signal is at most of the time. And signals persist on the screen for a few seconds before fading out allowing you to see signals that come too fast to view in the spectrum graph. One can see the Wi-Fi signal, the Bluetooth Signals, and the Microwave Oven Signals that were present just a few seconds earlier.

 

IQ PlotsI /Q Plots
The I/Q plot consists of two plots, the I/Q Constellation (if available) on the left, and the I/Q Time Domain on the right. The Constellation data displays the In-phase (I data) vs. the Quadrature (Q data). The Time domain plot shows a trace for the In-phase (I data in green) and a trace for the Quadrature (Q data in red, if available in the mode).

 

Make measurements locally or remotely Measurement can be made remotely via the Internet around the globe. Ideal for remote monitoring applications.

 

  • Up to six traces are available as Trace Normal, Trace Average, Max Hold, and Min Hold.
  • Twelve Markers are available as Normal (tracking), Delta, and Fixed with Peak Search functions that can be assigned to any trace.
  • The Real-Time Level Trigger only captures signals over a certain level and is useful for viewing signals over the Internet.
  • For remote applications, Record data on the local PC and then use Playback to view the data without any Internet latency.
  • The widescreen view of a laptop or PC monitor enables enhanced viewing not available on instruments with built-in screens.
  • The intuitive GUI display makes it easy to operate for anyone familiar with a benchtop spectrum analyzer.

Aaronia’s portable RF handheld spectrum analyser range represents outstanding performance and price. The SPECTRAN series are a highly valuable tool for engineers performing EMC evaluation testing and testing for RF interference.

As well as being lower cost, the SPECTRAN RF units are much smaller, lower power and lighter than other RF spektrum analysers currently available. The low power consumption offers up to 9 hours of continuous operation from a charge which truly is a new record on portable analyzers.

Spectrum DisplayThe SPECTRANs offer RF service engineers a highly portable and cost effective tool that enables to carry a spectrum analyser to areas that have usually been not cost effective when using existing “portable” products and difficult or even impossible to access with bench top instruments offered by other manufacturers.

Our low cost and ultra portable handheld spectrum analyser ensure that site survey and RF testing can be performed on any site visit.

The SPECTRAN V3 series weighs less than 420gr and measures only 250 x 86 x 27 mm. The low weight and small dimensions make it a true handheld instrument, unlike other “portable” spectrum analysers which can be up to ten times the size and weight.
