Oscilloscope Recommendations

[Garey Barrell]

Alex -

One caveat...   The 22xx (non A) models have a congenital defect in the
power supply that causes them to hum annoyingly.  This was corrected in
the "A" models.   Some Non-A's were corrected by Tek, but many were
not.  I know, I have a 2215.   Great scope, and I prefer to think of the
hum as a "feature" in that it's impossible to turn everything off in the
lab and forget to turn off the scope!
