About This Product
A slide screw tuner is used on an X-band microwave bench to match a load to the line and reduce reflections. Students move the carriage and change the screw depth while watching the standing wave on a slotted line, which shows how a reactive element placed at the right point cancels a mismatch. Laboratories and colleges in Tanzania, Paraguay, Lesotho, Iran and Mauritius can buy the Slide Screw Tuner through an export order.
Frequently Asked Questions
How does the Slide Screw Tuner match a load?
A screw on a carriage enters a thin slot in the broad wall of the waveguide; changing how far it penetrates and where it sits along the slot sets the matching.
