Product Usage Instructions

Installation
Ensure the VSWR bridge is connected in line with the RF setup according to the desired measurement configuration.

Power Measurement
The VSWR bridge allows for inline RF power measurements up to 100W. Ensure proper power handling procedures are followed.

Frequency Range
The bridge is characterized for use in the frequency range from 200 kHz to 500 MHz. Ensure your application falls within this range for accurate measurements.

Directivity Adjustment
The ports Input/Output and Forward/Reflected can be exchanged,but note that directivity may slightly deviate from the specified values.

Introduction

The TBSWR-200K500 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-200K500 is characterized in the frequency range from 200 kHz to 500 MHz. The high power handling capability of up to 100W allows inline RF power measurements, and a variety of other applications. The insertion loss over the frequency range is typically between 0.2 and 0.7 dB, which is significantly smaller than the average 7 dB associated with VSWR – bridges.

FAQ

Q: What is the maximum power handling of the TBSWR-200K500 VSWR Bridge?
A: The TBSWR-200K500 can handle up to 100W for inline RF power measurements and a maximum of 35W for output shorted or open configurations.

Q: What is the typical insertion loss of the VSWR Bridge over its frequency range?
A: The insertion loss of the bridge typically ranges between 0.2 and 0.7 dB, which is significantly lower than the average 7 dB associated with VSWR bridges.

Q: Can the directivity of the VSWR Bridge be adjusted?
A: The ports Input/Output and Forward/Reflected can be exchanged, allowing for adjustments, but directivity may deviate slightly from the specified values.
