Featuring high performance, uncompromised design, and remote monitoring software, the GSP-830 3GHz Spectrum Analyzer is the latest evolution from GWInstek. The GSP-830 is one of the most advanced Spectrum Analyzer GWInstek has produced to date. The GSP-830 has an exceptional noise floor of -152dBm/Hz; combined with the optional GAP-802 preamplifier, the noise floor can reach a remarkable -172dBm/Hz. With a low noise floor, the GSP-830 is more than capable of finding limits; Trace Detection, combined with an easy-to-use interface, makes the GSP-830 an ideal solution for spectrum analysis. Using the Auto Sequence mode, advanced users can define their own macros in 10 Sequence sets. Repeat or Single run mode can be used to streamline repetitive tasks. PC connection is effortless and versatile supporting USB host/device, RS232C, VGA and GPIB (optional) for remote monitoring, control and analysis.


GW Instek now extends its Spectrum Analyzer product series up to 3GHz. As a new member, the GSP-830 inherits the advantages of high performance, affordable cost, ease of use, and light-weight portability, which are common in GW Instek products. Moreover, its extremely low noise floor greatly increases the measurement range, an advanced user interface brings a significant visual enhancement, and the rich measurement functions make measurements simple and easy. The GSP-830 offers the greatest performance/price value in the market.

Wide Measurement Range
With GW Instek's state-of-the-art design, the GSP-830's outstanding low noise floor level of -152dBm/Hz at 1GHz has extreme sensitivity for picking up weak signals. Along with the GAP-802 20dB-gain preamplifier, the GSP-830 reaches an equivalent noise floor level as low as -172dBm/Hz, further extending the measurement range.

Automatic Measurement
The GSP-830 can act as an automatic test instrument to eliminate the need for external computer control. Macros can be defined through the front panel keypad and stored into 10 Sequence sets. A sequence can include pause steps that can be used for observing the measurement results when necessary. Repeat or Single run mode can be selected based on application requirements.

Portable Power Operations
Equipped with two packs of Li-ion batteries, the GSP-830 can maintain normal operation for more than 3 hours. In DC operation mode, the GSP-830 can be powered by a 12-Volt power supply or a standard cigarette lighter in an automobile. The large internal memory of the GSP-830 means mass storage of measured traces, setup information, limit lines and user-defined macros is possible. With USB flash drive support for mass storage, weighing 6kg and a compact size, the GSP-830 is also a convenient tool for service engineers out in the field.

Advanced User Interface
The user-oriented interface design of the GSP-830 gives users the pleasure of handling complicated measurements with ease. A high-resolution 6.4" color TFT LCD provides crisp and clear images. Colored, user-defined traces allow small disparities to be seen at a glance. The Split-Window mode allows simultaneous monitoring of two different frequency bands on a single display. Under this split-window mode, the GSP-830 acts like two spectrum analyzers packed into single unit.

Feature-Rich Interface
The USB host port on the front panel supports flash drives for various functions, including loading/saving setup information, tracing data, and capturing screens. The rear panel USB slave port is used for PC remote control. The GSP-830's screen image can be sent directly to external monitors through the VGA port on the rear panel. These features make it easy to remotely monitor the results in special circumstances, such as EMI testing, group presentations, or discussions.

Free PC Software for the GSP-830
Through RS-232 or USB connection, EagleShot can transfer measurement data from the GSP-830 to a PC. Data can be printed as graphs or saved as a text file for further analysis. With the EagleShot software, the limit lines can be uploaded from the GSP-830 or edited directly on the PC. For marking and reading the captured signals on the PC screen, markers can be placed directly on the PC display as easily as doing it on the GSP-830 front panel. The latest version of EagleShot supports the GSP-830 in various application fields whilst maintaining compatibility with the GSP-827.
