I bought an TDS620 2/3 weaks ago on a public auction. I am very pleased
with it. Manuals you can find at tektronix.com . Repair parts...very
difficult..but if you keep the machine in good condition, the
opportunity of malfunctioning is minimal. Buying extra probes; I
recommend Ebay (United stated..but an second hand good TEK probe will
cost you at least 80 euro)

When you buy it let show him the start up screen !! A picture with al
tests passed is important. Sometimes with TDS500/600/700 they don't
pass the aquisition test because somebody ended too soon the probe
calibration function (cost about 20 minutes)...once I thought I killed
mij scope with this action, because I aborted the procedure, bute with
an new calibration procedure on the scope everything worked fine...

For dutch people:
ALs hij 'm maar 3 weken in zijn bezit heeft , 1 probe en waarcshijnlijk
missende kap voor het front..dan weet ik waarschijnlijk wat hij ervoor
op de veiling heeft betaald...moet je me ff mailen...

I have an opportunity to buy a TDS420 oscilloscope.

What is your opinion of this scope?

Are options and repairs available for it yet?

Where would you buy accessories for it?

TIA
