Aspen stocking spectrum analyser with advanced spectrogram and topography features

Aspen Electronics is now stocking the GSP-930 3GHz spectrum analyser designed and developed by GW Instek. Based on a next generation platform, the instrument offers advanced spectrogram and topography features and is aimed at the professional, industrial, advanced communication, education and R&D markets.

The instrument 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.

With 58 selectable RBW ranges, from 10Hz to 1MHz, and with EMI filter: 200Hz, 9kHz and 120kHz, the spectrum analyser 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 allows for high precision power measurements.

The spectrogram and topographic features enable the GSP-930 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 features include Spectrum Emission Mask (SEM), AM/FM Analysis and TOI/CNR/CSO/CTB measurements.

The high stability, large screen display, together with a user-friendly design and intuitive operation, ensures the instrument is easy to use, even though it offers advanced features. Built-in on-screen help facilities provide definitions and descriptions on the screen to guide users through measurement processes. The icons on the display will be familiar to most users, and clearly indicate the current setting and operational status of the product.

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.

Suitable for field service operations, the instrument is light weight and compact, with a battery option, fast warm up time and comes with a soft carry-case.

The GSP-930 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 spectrum analyser 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.
