ABSTRACT: This is the user guide for Maury coaxial manual tuners for the following models:
- MST981E
- MST981B
The MST981E & MST981B Series Manual Tuners are high performance precision manual slide screw tuners that achieve low through line VSWR and excellent matching values. They are available with 3.5mm and Type N connectors and cover a variety of frequency ranges. They feature micrometers for controlling matching level and a digital display for indicating carriage (phase) position. The tuners serve as a matching network for reducing reflections caused by mismatches present in a transmission line, or to introduce a controlled mismatch into an otherwise matched transmission line.
