GSP-930 Description

The GSP-930 is a 3GHz Spectrum Analyzer designed upon a new generation platform. The high stability, large screen display, light weight and compact size of GSP-930 benchmark a new standard for 3GHz spectrum analyzer in the market. Its advanced features, Spectrogram and Topography, greatly expand the application range and elevate the importance of a spectrum analyzer in the role as the irreplaceable RF analysis instrument.
GSP-930 provides a high frequency-stability of 25ppb (0.025ppm) and a very low noise floor of -142dBm (Pre-amplifier on) as the high sensibility measurement base. The flexible selection among 58 RBW ranges along with Spectrogram and Topographic features enable GSP-930 to capture and display transient, drifting and hopping signals in detail. The mixture of frequency domain information and time domain information facilitates the tracing of RF signal variations over time. Other remarkable features like Spectrum Emission Mask (SEM), Power Measurements, AM/FM Analysis and TOI/CNR/CSO/CTB measurements, make GSP-930 a useful instrument right fit into a broad range of applications.

High Stability for both Frequency and Amplitude Measurements

GSP-930 carries a very high frequency-stability of 25ppb over temperature variation, superior to the 1ppm frequency stability of most spectrum analyzers available in the market. The high efficiency heat dissipation design and the temperature-controlled ventilation fan maintain a stable-temperature environment for GSP-930 circuitry operation, which contributes to the high accuracy of amplitude measurements in all time and greatly shortens the warm-up period at power on. To best utilize the advantage of high frequency-stability, GSP-930 features a Marker Frequency Counter function, which enables the high accuracy frequency measurements up to 1Hz resolution.

Wide Measurement Range with Built-in Pre-Amplifier

GSP-930 carries an extremely low noise floor of -142dBm when the built-in Pre-amp is on, and -122dBm when the Pre-amp is off (2). With -142dBm noise floor and maximum input power up to +30dBm, GSP-930 provides a very wide measurement range, which makes the measurement of very small signal possible.
Remark (2) : Under ''Auto On'' mode, the preamplifier will be turned on automatically when the reference level is set at lower than -30dBm. Under ''Bypass'' mode, the preamplifier will be off in all time.
