Dear All,

After some shipping time, my E1938 arrived today! :-)  :-)  :-)

Thank you Rick!

First thing was examining the board, oscillator and the HP-test 
notes/labels. Most of the specs mentioned there are logical and numbers 
are very reasonable. ;-) However, one spec drew my attention: "Hz off 
freq. after warm up: -2,94". Does anyone know what it means? Is this the 
offset after warm-up without EFC applied?

The unit hasn't been powered up. Whit the hardware at hand I first want 
to read some docs to be sure about what I'm doing. For comparison, what 
other numbers are around for the "Hz off freq. after warm up"-spec?

Final result of the HP-test was: PASS. So, I assume this number is OK. 
What is your opinion? Looking forward to your reactions.
