Teledyne Technologies Inc. [TDY] yesterday said it has completed its acquisition of test solutions equipment provider LeCroy Corp. for $291 million, including debt.

New York-based LeCroy makes oscilloscopes, protocol analyzers and signal integrity test solutions for the computer, semiconductor and consumer electronics, data storage, automotive, industrial, telecommunications, military and aerospace markets. The acquisition broadens Teledyne’s analytical instrumentation business and provides it with a commercial channel for some of its products.

LeCroy had over $178 million in sales for its fiscal year that ended in July 2011 and was expected to post $200 million in sales in its most recent fiscal year ended last month. LeCroy, which now part of Teledyne’s Instrumentation segment, has about 500 employees.
