Direct Reading Type
- Direct reading frequency meter are absorption type frequency meter to give direct frequency on the dial provided. These are recommended for use whenever quick determination of frequency and easy readings are desired in laboratory and production testing.
- These consists of a section of waveguide connected to a tunable resonant cavity of high Q. The cavity absorbs some power at resonant frequency. These are designed to have 5 MHz resolution & off resonance VSWR of 1.01.
