- Purpose-built for forward/reverse power measurement in RF and EMC tests.
- Wide frequency coverage: characterized from 200 kHz to 700 MHz.
- Good directivity for accurate measurement separation of forward and reflected power.
- Low insertion loss (typically < 0.7–1.5 dB) across its operating band.
- Suitable for demanding RF setups Compact design with standard RF
- Ideal for EMC immunity tests, HF/VHF RF measurement setups, and general power diagnostics.
TBSWR-600K700
High Power VSWR Bridge
The Tekbox TBSWR-600K700 is a high-power VSWR (Voltage Standing Wave Ratio) bridge designed for forward and reverse RF power measurements in EMC immunity test setups — especially with BCI probes (Substitution Method) — and general high-power applications in the HF and VHF frequency ranges. It combines the wide frequency range and strong directivity of a directional bridge with the low insertion loss and power handling capability of a directional coupler.
