Vector Signal Generator (VSG)
The BTS Master’s Vector Signal Generator
is designed to be a signal source to
facilitate base station field testing of the
receiver’s basic performance when it
comes to:
• Sensitivity
• Adjacent Channel Selectivity
• Blocking
• Intermodulation Rejection
The BTS Master has the flexibility to
generate three signals in a variety of
combinations:
• Modulated, CW, AWGN
(Additive White Gaussian Noise)
• Wanted Signals (modulated or CW)
• One signal at 10 MHz or less
(with no interferer present)
• One signal at 5 MHz or less
(with interferer present)
• With or without AWGN
• Interferer (modulated or CW)
• One interferer at 5 MHz or less
• With or without AWGN
The BTS Master has the ability to output
complex waveforms. As an example,
you generate a W-CDMA signal and a
GSM interferer. It offers the capability to
generate complex waveforms including:
• LTE, TD-LTE
• W-CDMA, HSPA
• TD-SCDMA, TD-HSPA
• GSM, GPRS, EDGE
• CDMA2000 1X, 1x EV-DO
• Fixed WiMAX, Mobile WiMAX
• AM, FM
• QPSK, QAM
The BTS Master VSG has an output power
range to meet most testing requirements
from -124 dBm to 0 dBm.
Users can define their patterns in either
MATLAB
® or ASCII. Master Software Tools
Patter Converter can upload them into the
BTS Master.
At the initial release the MT822xB will have
a set of basic signals and other patterns
will be added on a periodic basis.
(Check the Technical Datasheet for the
latest specifications and pattern offerings.)
