NA7300 is the best combination of high speed, accuracy, productive and low cost. It helps reduce the testing time, incerease ouput, and lower the overall cost of components. The analyzer is qualified in testing typical RF components such as; Filter, Amplifier, Antennas, Cables, Taps and Splitters.


Amplifier Measurement

With high precision receiver and accurate signal level from signal source, NA7300 can perform qualitiative measurement: working frequency  range, gain, flatness, AGC feature, return loss and isolation, and gain compression of amplifier. Also, power sweep function can catch 1dB compression point of amplifier. NA7300 provides various tests and display modes to support high accuracy testing, especially for reflection strictly requested in bidirectional digital HFC network.


Splitter Measurement

NA7300 can measure transmission and reflection parameter of splitter including insertion loss, flatness, isolation, return loss and so on


Filter Measurement

NA7300 can not only test various types of filter transmission and reflection, but also with intelligent analysis module accurately display center frequency, NdB bandwidth, insert loss, Q value and group delay. Also its automatic Pass/Fail function can significantly speed up the test.


The special two windows mode helps users to test filter both in narrowband and wideband and all filter parameters list can be displayed.


Antenna Measurement

The main function parameters of antennna are gain, input impedance, standing wave ratio, polarization method, and return loss. With NA7300 you can easily test medium wave antennas, short wave antennas and the antennas with the frequency under 3000MHz.


NA7300 can get the cable loss transmission canstant through measure the cable's parameters: insertion loss, impedance, return loss, standing wave ratio and so on. And every point measurement speed can be set between 0.3ms~ 20ms.
