II、Product Description:
(1)2.7GHz Spectrum Analyzer:
The GSP-827 Spectrum Analyzer is a very handy instrument for RF measurement application, delivering a
superior combination of easy-to-use design and exceptional price/performance value enclosed within a highly
portable package. Covering 9kHz to 2.7GHz, the GSP-827 is designed to meet Production/Development
test demands of RF products as well as on-site Maintenance/ Installation of wireless communication
systems.
(2)Portable and Easy-To-Use Spectrum Analyzer with Exceptional Price/Performance
Covering a frequency range of 9kHz ~ 2.7GHz, the GSP-827 is designed to meet demands in production or development testing of RF products, maintenance or installation of on-site wireless communication systems.
The exceptional price/performance, high portability, and easy-to-use design make GSP-827 a very accurate
and convenient instrument for most RF measurement applications.
(3)High Portability and Large Memory Size With the AC/DC/Battery power operation, a light 4.5kg weight, compact size, and coverage from 9kHz to 2.7GHz, the GSP-827 is a very convenient tool for field servicing RF systems. 100 sets of memory for
saving 100 traces or setups make repetitive measurements and mass storage of test results possible. The
large memory size of the GSP-827 is also a useful feature for characteristic verification of products
and components. Repetitive measurement results can be saved internally, and then transferred to a PC
for further analysis.
(4)Exceptional Price/Performance Utilizing advanced synthesizer-based design, the GSP-827 delivers accurate and reliable measurements. The remarkable performance of -100dBm average noise floor and -100dBm ~ 20dBm wide input range greatly
expands the product application range. The ACPR, OCBW and CH power measurements make the
verification of wireless communication characteristics simple and easy. The Split-Window display
simultaneously shows waveform spectrums in two separate frequency spans. Setups make complicated
measurements a simple task. The optional built-in tracking generator with normalized output allows easy
performance testing of RF components and modules. All these innovative features reflect the
price/performance value of the GSP-827.
1. CH POWER / OCBW / ACPR
The GSP-827 provides versatile capabilities to measure Channel Power (CHP), Occupied Bandwidth
(OCBW) and Adjacent Channel Power Ratio (ACPR). These capabilities are essential to verify transmission
characteristics of wireless communication systems.
(I)CH Power :
By setting the channel center frequency and channel bandwidth, the GSP-827 automatically measures the
total transmitted power within the bandwidth of the specified channel.
(II)OCBW :
By setting the channel center frequency and the total percentage of transmitted power, the GSP-827
automatically indicates the bandwidth that represents the percentage of the total amount of transmitted
power.
(III)ACPR :
The ACPR measurement function allows users to check the interference or leakage power between the
designated channel and its adjacent channels. Being able to apply to sophisticated modern communication
systems, the GSP-827 has the capabilities to measure the power ratio between the specified channel and its
adjacent channels either within the same communication system or among different communication systems.
2. 10 Markers(Peak Track, Peak Search)
The GSP-827 allows operating flexibility under both Delta-Marker mode and Multi-Marker mode. Up to 10
markers can be selected to show their absolute frequency and amplitude in a table on the screen. The relative
frequency and amplitude of the selected markers-to-reference marker can be shown quite easily.
All Markers provide fast and comprehensive interpretations of measurements and full marking capabilities
including, Peak Search, Marker to Center, and Peak Track.
3. 100 Trace/State Memories
The GSP-827 provides up to 100 sets of memory to save or recall waveform and measurement set-ups. A
specified file name and date/time stamp can be attached to each saved file for easy recognization of all saved
information. With a large memory size, the GSP-827 facilitates measuring on site service and product
characteristic verification.
4. Limit Line
Upper and lower limit lines can be easily set to monitor abnormal signals under user defined conditions. Each
Limit Line can be set by linking points positioned by frequency and amplitude data.
5. Split-Wimndow
The Split-Window function allows you to view the frequency spectrum of an input signal on two separate
screen areas under two different settings. The split window function provides the value of two spectrum
analyzers in one instrument.
6. Tracking Generator
With the optional Tracking Generator, the GSP-827 becomes a convenient tool to verify characteristics of
dual-port components such as filters and amplifiers. The normalization process of the output signal
compensates the uneven signal loss caused by side effects from measurement cables and connectors to
ensure an accurate measurement.
7. PC Software
The GSP-827 is complimented with free PC software (EagleShot) to easily transfer acquired trace and the
associated data from the GSP-827 to a PC through the RS-232C interface.
8. Carrying Case
With the carrying case, the GSP-827 makes on-site RF measurements more convenient than ever. The
carrying case not only provides protection and portability for the GSP-827 but also carries test accessories
such as RF cables, antennas, and a battery to facilitate measurements.
