Publication Number: 587968 Rule Parts:  Publication Date: 04/09/2007
Keyword: Section 2.924, Multiple Crystals devices

First Category: Administrative Requirements
Second Category: Equipment Authorization Process

Question:   Can a device be approved under one FCC ID that uses Crystal A or Crystal B to operate at a fixed frequency, or would it violate the rule in Section 2.924 that requires the devices to be electrically identical?

Answer:   Devices using different internal hardware components, such as amplifiers and crystals, can result in different radio output power and/or frequency, and are therefore NOT considered electrically identical. Accordingly, the devices must be authorized under separate FCC IDs.
