The growing demand for throughput has been propelling the advent of new transmission technologies and features such as 5G-NR and 4G/LTE-A, smart antenna systems, massive-MIMO, and widespread use of small cells. The success of deployment of these new technologies, however, depends greatly on clean spectrum, free of interference, to maximize transfer rates. OFDM/OFDMA systems, such as 4G/LTE, 5G, or even the new WiFi 6.0 (802.11ax), require more detailed knowledge and multipath analyses of the RF communication channels within the whole area of deployment.

CellSpectrum PlusTM is a specialized and detailed Spectrum Analyzer spanning a wide range of spectrum for band clearance, interference analysis and other tasks necessary for most of wireless networks. The spectrum is retrieved from a Software-Defined Receiver with a defined set of markers within the supported frequency bands that samples and digitizes up to 100 MHz of spectrum at a time (real time collection and recording capabilities) with a sampling rate of up to 125 MSamples/s and 14-bit digitization – all samples can be geotagged. The receiver has a large dynamic range and automatic input level regulation to avoid saturation when close to transmitters. The system has a small form factor (light weight, with low power consumption).

The CellSpectrum PlusTM spectrum analyzer has two models covering up to the following frequency ranges: CD18 (CellDigitizer up to 18 GHz with CellSpectrum firmware) and CD27 (CellDigitizer up to 27 GHz with CellSpectrum firmware). 30 GHz and 40 GHz downconverters are available to extend the spectrum covered. Spectrum is captured and stored for instantaneous or future analysis. This provides great processing flexibility and can provide forensic evidence in specific scenarios.

CellSpectrum PlusTM includes the following features:

  • Test mode allows spectrum recording
  • Playback of recorded spectrum traces
  • Channel and range (user-selectable) power calculation
  • Collected samples are geo-tagged
  • Export ASCII files
  • No overlap or underlap when selecting the RBW and span
  • Maximum, average, current, and minimum values traces
  • Graph marks
  • Charts zoom in and out
