A new 3GHz spectrum analyser has been released by Aspen Electronics that is designed and developed by GW Instek. The company’s GSP-930 offers advanced spectrogram and topography capabilities, for 3GHz spectrum and so is a purposeful RF analysis tool. 

The instrument is aimed at the professional, industrial, advanced communication, education and R&D markets and features a frequency range of 9kHz to 3GHz, a high frequency-stability of 25ppb (0.025ppm) and a very low noise floor of -142dBm (pre-amplifier on), providing a high sensibility measurement base. 

The device has 58 selectable RBW ranges, from 10Hz to 1MHz, and comes with an EMI filter of: 200Hz, 9kHz and 120kHz. The device also features a TG option from 100kHz to 3GHz for the frequency characteristic measurements of RF modules, RFID tags, antennas and similar devices.  A power meter option also allows for high precision power measurements.

The combination of spectrogram and topographic features enable the instrument to capture and display transient, drifting and hopping signals in detail. The simultaneous capture of frequency and time domain information facilitates the tracing of RF signal variations over time.

Other notable features include Spectrum Emission Mask (SEM), AM/FM Analysis and TOI/CNR/CSO/CTB measurements. 

A combination of other design features include  high stability, large screen display, together with a user-friendly design and intuitive operation to ensure the instrument is easy to use, even though it offers advanced features.

A built-in on-screen help facility provides definitions and descriptions on the screen to guide users through measurement processes.

Up to four measurements made in four different modes, including normal trace, min hold, max hold and view, can be displayed at the same time using the split screen function.  The four traces can also accommodate measurement results under different detector modes.

The instrument is suited to many applications including field service operations largely because it is light weight and compact, with a battery option, fast warm up time and comes with a soft carry-case.

The device is equipped with various interfaces, including LXI, USB, RS-232 and GPIB (optional). The IVI driver is available for the remote control software development by means of LabView or LabWindows/CVI. A Micro SD slot and a USB Host interface facilitate memory expansion for mass data storage. An IF output (886MHz) is provided as the intermediate frequency signal of the RF input allowing users to develop their own applications.

The device is suitable for a wide range of design, manufacturing and field service applications in the RF arena, including communication engineering, wireless system development, antenna measurements, EMI pre-testing, mobile phone network repairs and surveillance systems.
