Rigol, Inc. (hereinafter referred to as: RIGOL) announced that it will launch VB1032 bridge January 1, 2016. DSA VB1032 can be used in conjunction with RIGOL of 800, DSA1000 series with built-in tracking the source -TG spectrum analyzer to the DUT antenna resonant frequency, etc., and related parameters S11 return loss, reflection coefficient, VSWR, etc. measurements. VB1032 has better directivity index (10MHz to 3.2GHz:> = 30dB), to better meet the needs of users of the reflection parameter measurement, has a broad application space.
The traditional S-parameter measurements using a network analyzer to carry out, but the network analyzer is usually expensive, its popularity and use far less frequency spectrum analyzer. In recent years, frequently shot RIGOL spectrum analyzer in the field, the introduction of spectrum analyzers million starting price, greatly accelerated the pace of the popularity spectrum analyzer, spectrum analyzer enable hardware engineers have become a necessary measuring equipment. DSA800-TG and DSA1000-TG series can realize filters, cables, amplifiers and other transmission characteristics of frequency response test with built-in tracking the source of the reflection characteristics of the test, you need to use an external measuring bridge or directional coupler achieve. Bridge and spectrum analyzers constitutes a scalar network analysis system, you can port DUT (DUT) for quick measure return loss, VSWR, reflection coefficient and the like. This approach allows you to buy spectrum analyzer which can measure the characteristics of the signal, and can measure the transmission and scalar properties of emission devices, greatly improving the efficiency of the instrument.

Spectrum analyzer S-parameter measurements with the tracking function needs, RIGOL DSA800 introduced DSA1000 Series and 5 Series spectrum analyzer with TG has features, DSA800 series frequency range from 9kHz ~ 7.5 GHz, DSA1000 series frequency range from 9kHz ~ 3 GHz, not only the performance is excellent, there is a wealth of advanced measurement capabilities, outstanding value for money, engineers fully meet application needs.
RIGOL has introduced a number of energy and DSA1000-TG series and DSA800-TG Series spectrum analyzer with built-in tracking the source of supporting the use of bridge products, including VB1020, VB1032, VB1040, VB1080.
Use RIGOL DSA1000-TG series and with DSA800-TG Series spectrum analyzers and VB series bridge with built-in tracking the source, allows engineers in the absence of the network analyzer situation, but also on the S signal measurements, allowing RF microwave engineers to simple, smooth and economical completion of development and testing work products.
