Radiation testing is not performed, but these VCXOs have been acceptable for use in
environments up to 100K rads by analysis of the components used. They are assembled
with all bipolar semiconductors with the exception of the ACMOS chip used for the
CMOS output which is purchased from a wafer that has been tested to a minimum of
100K rads total dose. A copy of the parts list and materials can be provided for review.

Manufacturing Information
QUARTZ CRYSTAL
For the #ight models, swept quartz shall be used in the manufacture of the crystals. For the Engineering models, non-swept quartz
shall be used.
TRAVELLERS
Travellers or Process Cards are used in the manufacturing and testing of all of the 1794 Series VCXOs and are available for customer
review. Copies of these Travellers can be provided with the VCXOs at time of shipment if so speci$ed on the purchase order.
TRACEABILITY and HOMOGENEOUS MATERIAL
Option Codes ‘S’ꢁ ‘R’only
Manufacturing lot and date code information shall be recorded, by VCXO serial number, of every component and all materials used in
the manufacture of that VCXO. Also all semiconductors used in the manufacture of any given Production Lot of VCXOs, shall be from
the wafer and have the same manufacturing lot date code. A Production Lot, as de$ned by Vectron, is all oscillators that have been
kitted and assembled as a single group. After the initial kitting and assembly, this Production Lot may be divided into multiple sublots
to facilitate alignment and test capacity and may be sealed at multiple times within a 13 week window.
TEST DATA
All Test Data is recorded by VCXO serial number. Copies of this data can be provided with the VCXOs at time of shipment if so speci-
$ed on the purchase order.
REWORK
All rework follows the requirements of Mil-PRF-55310 Class ‘S’for Option Code ‘S’and Class ‘B’for Option Codes ‘R’, ‘B’and ‘C’. The only
exception is the Select-At-Test components may be replaced up to four times.
