After a friend referred him to Copper Mountain Technologies, Tom requested a demo of the TR1300/1 and was instantly impressed with the 2-port USB VNA. “In 30 minutes, I had set up a UHF template and tuned three filter devices, I was blown away by the accuracy and repeatability of the measurements.” said Tom. Several attributes of the TR1300/1 have been beneficial to Red Dog Radios. The dynamic range allows Tom to tune duplexers more quickly and accurately than his previous instruments. The functionality of the software allows him to easily set up standards. And the USB connection offers freedom while making measurements. Being able to look at the software on a separate laptop screen, rather than a smaller built-in screen, means he can glance at the display while standing on a step ladder from several feet away without any misinterpretation.
