A major step forward in affordable technology.  I can perform measurements with the Copper Mountain Technologies' VNAs that a few years ago were well out of our price range. For such a compact unit, it is very precise.  Essentially it’s a portable lab-quality instrument that you can throw in a backpack. I very much enjoy using this VNA. It is compact and quite capable. The TDR function allows us to see line anomalies. We can sweep antennas with some external signal coming in. The automatic calibration is easy to perform, and exporting data allows the data to be included in a report. The markers and multiple chart formats allow one to see the same device under test (DUT) in multiple ways for a more comprehensive understanding of the DUT. Much more portable than our old HP VNA.

The advent of the R180 has enabled new technologies that are cutting-edge. We've found them to be less expensive and efficient. Technical support is great. It's an individual working with us, so it's not just buying one off the shelf, and if you need to do something good luck to you. It's that Copper Mountain Technologies works with us to figure out exactly what we need to do to solve our problem for our customer. And that's really different from other companies that we've worked with.

The features, ease of use, and accuracy are top priorities for measurements. Dealing with mmWave measurements is very difficult, any misalignment can contaminate your measurement. You want to make sure the system is accurate and stable. Rerunning measurements costs you time and money. Data must be easy to manipulate and post process, which is a feature of Copper Mountain Technologies’ USB vector network analyzers. We were pleasantly surprised at how the measurements from the CobaltFx FEV-10 compared to other providers’ measurements. We chose the CMT VNA for the ease of use and cost. We work with all kinds of antennas: radar, electronic warfare, and telecom. These require testing in different types of environments and the size and portability of the FEV-10 frequency extension system allowed for that. Customer support has been superior. The big guys put you in the queue, but Copper Mountain Technologies responds to us quickly, even though we are a small company. Love the intuitive user interface. We love this thing.

The C1220 has been working exceptionally – we are very happy with it. We have used it extensively to test for losses/reflections through waveguide and coax components. It does exactly what we needed it to do.

The dynamic range of the Copper Mountain Technologies' 8GHz model was nearly identical to or slightly better than the 8.5GHz Keysight ENA unit.

The VNA evaluation was indeed very good. Integration was smooth, and it is just as fast as their larger counterparts. The test results provided were within our required accuracy. Price is slightly over that of some competitors with similar capabilities. We can definitely recommend it.

The TR1300/1 1.3 GHz VNA offers excellent price/performance for any educational institution. The unit provides all conceivable functions with easy intuitive interface, thus minimizing retraining of specialists who are familiar with more expensive and branded product. We believe this is a great tool for anyone who needs to use VNA, saving cost and yet provide excellent performance. The special note is the ability of the software to adjust the output frequency of the reference generator - it is a good option that no one, except for Copper Mountain Technologies, has - a great tool to configure filters. We have bought 5 units and plan to increase the number to 100 for both educational and production environment.

We developed a portable test system to allow operators to carry these to test antennas using the 1-Port R54 or R60. The test system is equipped with touchscreen monitor and it is very convenient and tests very well. It’s nice to have a computer to store data on compared to the traditional VNA setup before.

“Copper Mountain support has strong expertise and deep understanding of VNAs. Response times to customer request are swift and support team is clearly dedicated to resolve the customer problems.”
