[time-nuts] Wenzel 10811's?

[Christopher Hoover]

I acquired a couple of OCXO's that were manufactured by Wenzel.  They look
exactly like 10811B's, with feedthru's and SMB connectors.

 

Both have the same Wenzel part number and one is also marked as "HP 10811E."


 

The labels are:

 

Wenzel Associates

Austin, Texas U.S.A.

HP 10811E

500-05741

10 MHz

Osc. +12VDC

Oven +20VDC

2036-9716

(yellow dot)

 

 

Quartz Oscillator

Wenzel Associates

Austin, Texas U.S.A.

Model: 500-05741

Freq: 10 MHz

Input: +12 & + 24VDC

S.N.: 6521-9751

 

 

Does anyone know the story behind these?   Did HP's needs exceed its
in-house production at some point and Wenzel asked to fill the gap?  I'm
guesing from the serial number's these were made in 1997.

 

I'm also looking for specs.
