GSP-827 Spectrum Analyzer

Portable and Easy-To-Use Spectrum Analyzer with
Exceptional Price/Performance

GSP-827 covering 9kHz ~ 2.7GHz frequency range, is designed to meet the demands of production or development

tests of RF products, and 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 handy instrument for most of the

RF measurement applications.

High Portability and Large Memory Size :

With AC/DC/Battery power operation, 4.5kg light weight, compact size, and 9kHz ~ 2.7GHz frequency coverage, GSP-827

is a very convenient tool for the field service of RF systems. The 100 sets of memory of GSP-827 to save 100 trace/set-up

make repetitive measurements with mass storage of test results possible. The large memory size of GSP-827 is also a

useful feature for the characteristic verification of products and components. The repetitive measurement results could be

saved in GSP-827, and then transferred to the PC for further analysis.

Exceptional Price/Performance :

Utilizing advanced synthesizer-based design, GSP-827 delivers accurate and reliable measurements. The remarkable

performance of -100dBm average noise floor and -100dBm ~ 20dBm wide input range, greatly extends the application range

of the product. The ACPR, OCBW and CH power measurements make the verification of wireless communication
characteristics simple and easy. The split window display to simultaneously show the spectrum in two separate frequency
spans and set-ups makes the complicated measurements a lot easier. The optional built-in tracking generator with normalized

output gives a useful mean for the performance test of RF components and modules. All the GSP-827 innovative features

reflect to the price/performance value of the users.

CH Power/OCBW/ACPR

OCBW MeasurementChannel Power Measurement

GSP-827 provides versatile power measurement capabilities including Channel Power(CHP),

Occupied Bandwidth(OCBW) and Adjacent Channel Power Ratio(ACPR), which are essential

to the transmission characteristics verification of wireless communication systems.

CH Power :

With the setting of channel center frequency and channel bandwidth , GSP-827 automatically

measures the total transmitted power within the set bandwidth of the designated channel.

OCBW :

With the setting of channel center frequency and the percentage of total transmitted power,

GSP-827 automatically indicates the bandwidth that represents the set percentage of total

transmitted power.

ACPR :

ACPR measurement function allows the user to check the interference or leakage power

between the designated channel and its adjacent channels. Due to the sophistication of the

modern communication system, GSP-827 has the capabilities to measure the power ratio

between the designated channel and its adjacent channels either within the same

communication system or that of a different communication system.

Adjiacent Channel Power Ratio

10 Markers(Peak Track, Peak Search)

Multi-Markers Mode Delta Marker Mode

GSP-827 gives the high operation flexibility under both Delta-Marker mode and Multi­Marker mode. Up to 10 markers could be selected to show their absolute values of
frequency and level in a table on the screen. The relative values of frequency and level of
selected markers-to-reference marker could be shown under an easy operation process.
All Markers , each with full marker capabilities including Peak Search, Marker to Center ,
and Peak Track, provide fast and comprehensive interpretations of measurements.

100 Trace/State Memories

100 Sets of Trace/State Memories

GSP-827 provides up to 100 sets of memory to Save and Recall the Waveform and the
Set-Up of measurements. The specified file name and the Date/Time stamp could be
attached to each saved file for easy recognition and analysis of all the saved information.
With large memory size, GSP-827 greatly facilitates the measurements of on site service
and the product characteristic verification.

Limit Line

Limit Line for Pass/Fail Testing

The Upper Limit Line and Lower Limit Line could be easily set to monitor the abnormal
signals under user's definition. Each Limit Line could be set by linking the points, which
are positioned by entering the values of both frequency and level referring to the
frequency axis and the level axis.

Split Window

Split Window To Observe Two Different Signals

Split Window allows user to view the frequency spectrum of an input signal on two
separate screen areas under two different settings of GSP-827 . This useful feature of
two-measurements-in-one usually means the value of two-instruments-in-one.

Tracking Generator

Tracking Generator To Observe Characteristic of Filter

With optional Tracking Generator, GSP-827 becomes a handy tool to do the characteristic
verification of dual-port components such as filters and amplifiers etc. The normalization
process of output signal compensates the uneven signal loss caused by the effect of
measurement cables and connectors, and therefore ensures an accurate measurement.

AC/DC/Battery Power Operation

AC/DC Battery Pack

In the field service environment or the places without AC power , GSP-827 with optional
AC/DC/Battery operation gives the convenience to use a lab instrument without AC power,
and maintains the lab measurement accuracy at the same time. A soft carrying case and
the DC power cable with car lighter plug for GSP-827 are also available to facilitate the
outdoor applications.
