Specifications listed represent optimal conditions and are not subject to warranty. All

SGC products must be used with compatible equipment

*Example: at 14.2 MHz = 14.2 x 3 = 42.6 Hz; A total frequency drift of 42.6 Hz for a temperature change

of 10º C. If the ambient temperature changes from 20º to 30º C, there could be a drift of 42.6 Hz.

SGC reserves the right to modify specifications without notice.
