Are you confident you're interpreting VSWR and return loss data correctly?
These two metrics appear on virtually every RF cable test report, yet they're often misunderstood or misapplied. The result? Engineers can end up chasing nonexistent problems—or worse, overlooking real performance issues.
In this latest article from Pasternack, we break down:
✅ What VSWR and return loss actually measure
✅ Why lower VSWR and higher return loss indicate better impedance matching
✅ How to evaluate performance across frequency, not just a single data point
✅ Common causes of poor cable performance and reflected power issues
✅ How to use test reports to improve troubleshooting and measurement accuracy
Whether you're working in RF test, microwave systems, aerospace, defense, wireless communications, or manufacturing, understanding these measurements can help reduce downtime, prevent unnecessary cable replacements, and improve system reliability.
