Product Usage Instructions

Installation:
Ensure the VSWR bridge is securely connected to the appropriate test setup using the provided RF connectors.

Power Measurement:
The VSWR bridge allows for forward/reverse power measurements up to 50W. Connect the RF source to the input port and the load to the output port for accurate power readings.

EMC Immunity Testing:
For EMC immunity tests with BCI probes, ensure proper setup of the VSWR bridge in the test configuration following the substitution method guidelines.

Operating Principle:
The ports Input/Output and Forward/Reflected can be exchanged, but note that directivity may deviate from the documented values in such cases.

   A: The dimensions are 113 mm x 60 mm x 35 mm, and it weighs 290 g.

Introduction

The TBSWR-600K700 high power VSWR – bridge is designed for forward / reverse power measurement in EMC immunity test setups with BCI probes (Substitution Method) and general high power applications in the HF and VHF range. The bridge combines the wide frequency range and directivity of a directional bridge and the low insertion loss and power handling capability of a directional coupler. The TBSWR-600K700 is characterized in the frequency range from 200 kHz to 700 MHz. The high power handling capability of up to 50W allows inline RF power measurements, and a variety of other applications. The insertion loss over the frequency range is typically between 0.7 and 1.5 dB, which is significantly smaller than the average 7 dB associated with VSWR – bridges.
