Customised Oscillators
These types of customised oscillators represent only our most popular units from a much
wider range. As with all frequency control products the majority of users require unique
specifications for many of their products. Hy-Q specialise in custom designs and
hence any criteria which is not met from our standard range can usually be incorporated
into a custom design. Whatever the requirement, even if it seems well outside the range of
the standard products on offer, our technical staff are always available to discuss your
application and decide upon the device specifications that best suit your needs.

Note |
| Ageing: |
Ageing specifications are based on
experience of our previously manufactured devices and are not explicitly guaranteed. |
