The Fastest Microwave Counter
The CNT-90XL Microwave Counter/Analyzer sets a new industry standard for microwave frequency analysis & outperforms any microwave Pulse or CW counter on the market regarding resolution, speed and acquisition time. The CNT-90XL is the worlds fastest Microwave counter & offers a measurement speed up to 250,000 frequency samples/s, for advanced statistical analysis & for analysis of frequency or power transients.

The multi-functional CNT-90XL also serves as a 400 MHz general purpose timer/counter, with unique ease-of-use with analysis capabilities to view variations in signal parameters both numerically & graphicall

Applications and Features

• Pulsed, Chirped & Doppler Radar testing & calibration

• Microwave link carrier calibration

• Satellite communication equipment testing

• RF & microwave instrumentation calibration

• RF components & modules, including YIG & VCO testing

• Medical RF equipment testing

Product Features & Benefits

• Pulsed RF measurements (optional) includes Pulse Width to 30 ns, PRI/PRF, Frequency in Burst, Power in Burst

• Fast high-resolution frequency or power measurements, for modulation, doppler shifts, or transient analysis

• Very short acquisition time of 25 ms (Auto) or zero (Manual)

• High sensitivity (-33 dBm)

• Statistical processing & graphical histogram, trend & modulation display

• Affordable microwave frequency counting

Battery Option
The CNT-90XL has an optional battery pack with 90 Wh capacity, capable of mains-free operation for at least 4.5 hours. In stand-by mode the battery pack can keep an OCXO warm & running for over 24 hours.

TimeView / Modulation Domain Analysis Software
The optional Modulation Domain SW TimeView is the ultimate tool to view & analyze dynamic frequency changes in real-time, utilizing the high-resolution PC screen, marker read-outs & processing, FFT-calculation to find modulation frequencies, ADEV calculation of short-term stability & more

Excellent Graphical Presentation
One of the great features of the CNT-90XL is the graphical display and the menu oriented settings. The non-expert can easily make correct settings without risking costly mistakes. The multi-parameter display shows auxiliary measurement values such as Power level in dBm in Frequency measurements.

Measurement values are presented both numerically and graphically. The graphical presentation of results (histograms, trends etc.) gives a much better understanding of the nature of signal jitter. It also provides you with a much better view of changes vs time, from long term trends like slow drift, to fast modulation and transients. Three statistical views of the same data set can be viewed: Numerical, Histogram and Modulation/Trend. It is very easy to capture and toggle between views of the same data.

When adjusting a frequency source to given limits, the Limit qualifying tool gives fast and accurate visual guidance. Tolerance limit markers are visually displayed and the actual frequency is graphically displayed inside or outside the limit markers. Passing the limits will cause an alarm indication.

The graphical display examples below show the frequency changes over time directly on-screen, for example Doppler frequency shift in speed radar sensors, fast power switching, FM or AM. Built-in statistical processing presents numerical stability data and also frequency distribution histograms on-screen for analysis of frequency stability or modulation.
