Spectrum analyser has 9kHz to 3GHz frequency range

The Amplicon test and measurement team has recently introduced the N9320B spectrum analyser. It has a 9kHz to 3GHz frequency range and optional features including tracking generator and preamplifier, they are an ideal addition to any test department.

The new low cost and easy to use spectrum analyser from Keysight allows in-depth testing and analysis while still being a viable solution for many different business sectors such as R&D, QA or university research.

The N9320B has the features of a high-end spectrum analyser including a 10ms non-zero span sweep so that test timing is greatly reduced. This, paired with the ability to carry out repeated tests through the use of shortcuts and one button auto-tuning translates to a quicker and easier way to find desired measurements, making the N9320B suitable for production environments where repeated testing on large quantities of products is required.

Industry standard SCPI language for automated test programming is supported as well as multiple options for connectivity, with USB, LAN and GPIB interfaces included as standard. The N9320B also has a resolution bandwidth (RBW) from 10Hz to 1MHz allowing a wide range of frequencies to be resolved, as well as wide or short sweeps to be completed depending on the required resolution.

The N9320B has other optional features to help improve functionality. It has a tracking generator, allowing the spectrum analyser to be used for measuring the frequency response, conversion loss and return loss along with many other measurements required within network and RF systems.

Also available as an option is a preamplifier, this will improve the sensitivity of the analyser. This is achieved by decreasing the noise figure of the preamplifier/analyser combination, so as the gain of the preamp increases and noise figure decreases the sensitivity increases.
