Just got my cheapo 5680A. It was accompanied by a little teddy bear
clutching a L7805CV !
Got a couple of questions.
1) What is the expected 10MHz peak to peak voltage. FEI doc seems to
indicate 0,5V but I am getting only 200mv.
2) What is the sensitivity to 15V input level. I am only measuring
14,722 (stable) on Pin1.
3) Could this low input voltage affect output voltage?
The box locks after a couple of minutes but my TDS 210 is showing a very
jittery ( 9,98-10,02 MHz ) but well formed sine wave for 8 hours of
being powered on. Could this also be an artefact of low main power?
