GTS-A6 Vector Signal Analyzer ,10 MHz to 6 GHz

GTS-A6 Main Functions

• General Spectrum Analysis

For conventional stable or periodic signals, the GTS-A6 provides broadband spectrum testing, including frequency and power measurements.

• Waterfall Display

GTS-A6 can display the frequency and amplitude change of the spectrum as a function of time in the form of waterfall display (Spectrogram), making the spectrum change at a glance.

• Digital Signal Demodulation

GTS-A6 supports ASK\PSK\FSK\QAM digital signal demodulation. Provide information such as spectrum, constellation, and EVM.

• LTE Signal Demodulation

GTS-A6 provides TDD-LTE and FDD-LTE downlink signal demodulation. Obtain spectrum records, time-frequency resource mapping, constellation, channel decoding, EVM, etc.

• NB-IoT Signal Demodulation

GTS-A6 provides air interface information demodulation for NBIoT. It can present multi-cell coverage and interference in the current wireless environment.

• FM Demodulation

GTS-A6 provides FM demodulation. The demodulated audio data can be stored in computer.

• Zero Span Mode

When analyzing the time domain characteristics of signal, user can set the span of instrument to 0 and enter zero span mode (like the oscilloscope). Video trigger can be used in this mode.


• Laboratory RF test

GTS-A6 vector signal analyzer can perform RF testing in the laboratory. GTS-A6 combines GTS-G6 vector signal source can test intermodulation distortion of amplifiers, mixers, and receivers. This system can also test antennas, amplifiers, and attenuators’ performance such as bandwidth, frequency response, and gain.

• RF & Microwave Teaching Application

GTS-A6 vector signal analyzer, combine with GTS-G6 vector signal source, enables a demonstration of the testing of RF microwave devices. It reduces the complexity of RF microwave professional teaching and meets the teaching needs of telecom and electronic engineering related majors.

Compact Size & Fast Deployment

GTS-A6 is compact and easy to set up. User can easily carry to field and quickly build the test environment.

• System Integration & Secondary Development

GTS-A6 vector signal analyzer has a small size, superior specifications, comprehensive telecommunication & general demodulation support, and an open API interface. It also offers three different product models: full-size USB module, small-size USB module and PCB module. Thus, GTS-A6 can meet the system integration needs of different users.
