Vernier Reduction drives are used to slow the rate of rotation for various devices, most usually air variable capacitors. Our drives have a consistent 4.5:1 gear ratio, which allows for very fine tuning of an air variable capacitor. This becomes very important when the point of resonance is extremely sharp and hard to hit.
Testing a Capacitor With a Multimeter You can use a multimeter to test many things, including a capacitor''s health. To fully grasp how you can test a capacitor with a multimeter, you need to check the RC (resistive-capacitive) time constant. This is the time it takes for a capacitor to amass a voltage equal to 63% of the input voltage.
This article describes a method for designing a frequency-tunable antenna using a microelectromechanical system (MEMS) digital variable capacitor (DVC) as the tuning element in the antenna aperture. The design example targets a smartphone where the low frequency response of the antenna is tunable from 700 to 960 MHz while the high …
How to test capacitors without Desoldering Below 3 methods to identify the faulty capacitor. 1. Test a capacitor with an ESR Meter. The ESR meter device determines the equivalent series resistance without desoldering or removing it from the circuit board. This device can not measure the capacitance but can test the capacitor. You Can Buy It Online.
