yig device

[′yig di‚vīs]
(electronics)
A filter, oscillator, parametric amplifier, or other device that uses an yttrium-iron-garnet crystal in combination with a variable magnetic field to achieve wide-band tuning in microwave circuits. Derived from yttrium-iron-garnet device.

As the YIG devices scan, they do not follow the tuning ramp exactly and build up dynamic lag that can be thought of as "magnetic inertia.
When combined with the dynamic characteristics of YIG devices, it is virtually impossible to perform automatic "stop on scan" acquisition within the time that a weak signal may be present.
While scanning, both YIG devices are open-loop and proper alignment is critical to operation.
