Datum Inc.

Datum Inc., an Anaheim company that shed its money-losing mini-computer line and now concentrates exclusively on precision frequency and timing devices, last week reported its highest-ever quarterly and annual earnings.

For the fourth calender quarter, Datum posted profits of $480,000, nearly 6% higher than the $454,000 in the year-earlier period. Quarterly revenues were $5.3 million, 23% above those for the comparable 1983 quarter.

For the entire year, the company’s profits hit $1.5 million, 36% above the $1.1 recorded in 1983. Annual revenues were $19.4 million, 4% higher than the $18.6 posted in 1983.

Datum executives, who spent most of 1982 and 1983 revamping the company’s product line, said the latest results indicates that their strategy has worked. Beginning in 1982, Datum began to shed its computer products manufacturing and focus on its precision frequency and timing device operations.

The switch allowed the company to cash in on the growing demand for their new products from defense and space agencies. In addition to the military, Datum’s products are used in electronic medical instruments, airport control towers, commercial aircraft, television transmitters, electric power systems, satellites and the NASA space shuttle program.
