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.
