I have datasheets (or equivalent thereof) for
HP 10543
HP10544A
HP10544B/C
HP10811A/B
HP E1938A
OSA 8600
OSA 8607
SRS SC 10
FTS1200
Symmetricom 1000B
I will setup a spreadsheet for these that tabulates EFC voltage limits
etc and calculates the required drifts etc.
I can export the results as a pdf file or in some other format if required.
I use Open Office to allow cross platform compatibility.
Spreadsheet can also be saved in Excel format if required.
I have FreeBSD, Linux and Windows XP/2K/98SE machines available.
If anyone has data for additional OCXOs they wish to include please post
a link or send me (off list) the datasheet as an attachment.
I will periodically post the updated OCXO list
I should be able to post a preliminary table by 1300 UTC.
