Description :

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.

The user friendly design of GSP-930 helps reduce user’s stress and anxiety in using a high-tech instrument. To help user easily get access to the regulations and definitions of the measurement terms under current operation, the built-in On-Screen-Help provides definition descriptionon the screen to guide user through measurement processes without checking into documents. The widely used Icons on the display clearly indicate the current setting and operation status of the product, allowing user to handle the measurement scenario all at a glance. The wake-up clock automatically turns on the power of GSP-930 at user’s pre-set time, which can be used to warm up the instrument in advance before the measurements are made to ensure the accuracy of measurement results. The Pass/Fail Limit function allows user to perform repetitive go/no-go measurements by template inspection instead of time-consuming value reading. The Sequence function provides an easy programming feature for user to edit and run measurement routines on GSP-930 screen without the need of a PC.

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 enable the memory size expansion for mass data storage. An IF output (886MHz) is provided as the intermediate frequency signal of RF inputfor users to develop their own applications. Carrying abundant communication interfaces, user-friendly operation, large screen display, light weight, compact size, and battery power operation(1), GSP-930 is developed upon a high-tech platform to provide ultimate customer benefits.

Remark (1): Battery pack is optional.

 

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.

Marker Frequency Counter
 
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.


Built-in Pre-Amp
 
Digital IF Design provides Wide RBW Selections with High Accuracy
Adopting an advanced digital filter design, GSP-930 is able to provide 58 resolution bandwidth (RBW) selections. The RBW is selectable in 1-3 step increase from 10Hz to 3kHz, and in 10% step increase from 10kHz to 1MHz. The wide selection of RBW is able to maintain a consistent measurement result of filter shape, and enable the best accommodation between RBW and sweep speed to gain ultimate measurement accuracy. GSP-930 also provides RBW selections of 200Hz, 9kHz and 120kHz for EMI standard compliance. A unique analog to digital conversion design is used to achieve high-resolution amplitude measurements within full dynamic range. With high-resolution A to D conversion, GSP-930 greatly reduces the uncertainty and increases the accuracy of small signal measurements.

Advanced Display Modes Paraphrase the Signal into Different Views
The conventional Spectrum Analyzer is not able to effectively measure transient signals or hopping signals due to the continuous update of current spectrum display. GSP-930, carrying Topographic technology, displays signals in various colors depending on the occurrence counts of each individual signal. This allows user to clearly distinguish transient signal, drifting signal and hopping signal from the entire spectrum of consistent input signals. The Topographic mode is especially useful to detect the transient interference signal in the telecommunication system, or to clearly display the transient behaviors of various types of telecommunication modulations like FSK, CCK and OFDM.

Topographic (top) display distinguishes two signals overlapping on the same frequency spectrum.
 
GSP-930 provides a powerful Spectrogram feature to simultaneously acquire Frequency Domain information and Time Domain information with dual-window display. Under Spectrogram mode, the X axis shows a line of frequency spectrum with different colors to represent different power levels of various-frequency signals, and the Y axis shows the time progress with current spectrum to always appear on the top of the display and with previous spectrums to roll down toward the bottom. The simultaneous provision of frequency domain information and time domain information makes Spectrum Analyzer a powerful instrument in most of the RF signal analysis applications.

Spectrogram (top) display shows a FSK signal
 
In addition to Topographic and Spectrogram display modes, the split window feature can also perform dual frequency band measurements under Spectrum mode. With upper display window and lower display window to show separate measurement results under separate settings, GSP-930 is very useful for harmonic signals measurements or far-off frequency signals measurements.

Four Traces with Display-and-Detector-Independent Settings
GSP-930 is able to display four measurement traces under four measurement modes, including Normal Trace, Max Hold, Min Hold and View, at the same time. The four measurement traces can also accommodate measurement results under various detecting modes, including PK+, PK-, Normal, Sample and Average.

Spectrum Emission Mask for a Variety of Communication Standards
GSP-930 includes Spectrum Emission Mask (SEM) measurement as a standard feature for RF emission power measurements of telecommunication systems. SEM is used to regulate the maximum power emission of a system during signal transmission as to avoid cross-over interference imposed on other systems in the neighboring transmission channels. GSP-930 has a variety of built-in SEM masks to comply with telecom standards, including 3GPP, 802.11b, 802.11g, 802.11n and 802.16. User can also create his/her SEM according to own definition.

Spectrum Emission Mask
 
Gate Sweep
In some of telecom systems, like Rader system and TDMA system, the signal transmission is done through periodical power emission applying TD (Time Division) technology. As the periodical power emission doesn't occur synchronously with the sweep time of spectrum analyzer, the TD signal measurement becomes a challenging task to the users. GSP-930, carrying Gate Sweep function, is able to do gated measurement over a complete time slot of periodically emitted signal. With external trigger signal input, GSP-930 is able to perform TD signal measurements perfectly.

Power Measurements
GSP-930 provides various Power Analysis functions for telecom channel measurements, including ACPR, OCBW, Phase Jitter and N-dB. With the display of channel bands in various color codes, and the split windows to show spectrum trace and measurement results simultaneously, GSP-930 is a very useful and convenient instrument for power analysis of telecom systems. The measurement function of Third Order Inter-modulation (TOI), caused by the nonlinearity characteristic of device or system, is also included to measure the inter-modulation distortion of two-tone signal.

Limit Lind and Pass/Fail Test
The Limit Line function of GSP-930 sets the upper limit or the lower limit for amplitude measurements, and provides user with a quick view of Go/NoGo inspection without the need to get trace readings. Three methods are available for Limit Line editing. The point-by-point data entry, the Trace Data to Limit Line Data conversion, which creates limit line by setting the offset values of existing trace pattern, and the Marker Data to Limit Line Data conversion, which uses markers to create limit line. An open-collector alarm output is available at the rear panel, which allows user to connect an external alarm for sound or other indications of Go/No-Go test result.

Wake-up Clock for Power-on Time Setting

The built-in wake-up clock enables the time pre-setting of GSP-930 power-on. This allows the setting of a prior warm-up time of the product at user's convenience, and enables accurate measurements according to the working schedule without waiting.

The Sequence function provides an easy programming feature for user to edit and run measurement routines on the GSP-930 screen without the need of a PC. GSP-930 can accommodate 5 Sequences of test routines with each Sequence routine to include up to 20 test steps. The multiple Sequences can also be chained freely to form a flexible test program like ATE test software.
