PTE was the predecessor of what is now well know Rohde & Schwarz (R&S) in Munic

PTE was established by Dr. Rohde and Dr. Schwarz in 1933.
During the last period of World War Two, PTE information sometimes appeared as R & S. However, to my knowledge, its official Company designation originates from shortly after Germany surrendered, in May 1945.
Significant for the Rohde and Schwarz Company may have been, that Munic was within the American Zone (influence). In a post war British report, they were very disappointed that they could not get what they utterly wanted from Rohde and Schwarz.

Quoting BIOS Final Report No. 1228 pages 15-16: ... Dr. Rohde is obviously reluctant to divulge all his latest designs and admitted that he was holding these back until he could once again market them as a business proposition. Since this firm is in the U.S. zone and American authorities tend rather to complain that investigating teams are upsetting production, little could be done to go more deeply into the latest developments of the factory. It is suggested, however, that such an investigation should be carried out with any compusory powers that might be necessary.
