UNI-T UT-RB60 VSWR Bridge: Technical Specifications and Applications
The UNI-T UT-RB60 is a VSWR bridge designed for measuring S11 parameters such as return loss, reflection coefficient, and voltage standing wave ratio (VSWR).
Product Introduction
The UT-RB60 is used with the UNI-T UTS3000T+ series to measure S11 parameters such as return loss, reflection coefficient, and voltage standing wave ratio (VSWR) for the device under test. The UT-RB60 VSWR bridge features an N-type (female) port configuration.
Port Descriptions:
- IN: Signal input terminal. Connects to the tracking source output of the spectrum analyzer.
- OUT: Signal output terminal. Connects to the RF input terminal of the spectrum analyzer.
- DUT: Terminal used to connect to the device under test.
Diagram Description (Product Introduction): A block diagram illustrating the UT-RB60 VSWR bridge with three ports labeled: 'IN' for signal input, 'OUT' for signal output, and 'DUT' for the device under test. An arrow shows signal flow from IN to OUT.
Measurement Connection
The connection method between the UT-RB60 and the spectrum analyzer is shown in the figure.
Connection to the Spectrum Analyzer:
Use two double N (male) adapters to connect the spectrum analyzer's tracking source output to the IN port of the VSWR bridge and the RF input of the spectrum analyzer to the OUT port of the VSWR bridge.
Connection to the Device Under Test (DUT):
When connecting to the DUT, use as few cables or adapters as possible to avoid introducing additional reflections.
Diagram Description (Measurement Connection): A diagram showing the connection setup. A spectrum analyzer is connected to the UT-RB60 VSWR bridge. The spectrum analyzer's tracking source output connects to the 'IN' port of the bridge using a double N (male) adapter. The spectrum analyzer's RF input connects to the 'OUT' port of the bridge, also using a double N (male) adapter. The 'DUT' port is connected to the device under test.
Application
- Measurement of S11-related parameters for passive devices such as filters, amplifiers, and mixers.
- Measurement of antenna frequency and Voltage Standing Wave Ratio (VSWR).
