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.
