Be careful with probes also. Many are not rated for high voltage and will
fail if clipped to a high voltage signal for long periods of time. gfz

Subject: Re: [Amps] LeCroy scopes
LeCroy is a manufacturer of electronic scientific instruments. Their
instruments are designed to meet the needs of researchers and not those
repairing or aligning equipment. An example a LeCroy digitizing
oscilloscope will properly average a number of waveforms while some of the
Tektronix scopes will not. Some of the older digital Tektronix scopes use
an algorithm that is not a true average but does appear to the eye to be,
which is generally good enough unless you are gathering statical data in an
experiment.
HP and LeCroy Scopes (older ones at least) do not have as good of
input amplifiers as the equivalent Tektronix scope. Almost all Tek scopes
will allow input signals up to about 400 volts peak on their input with out
damage to the scope, even on the most sensitive ranges. This is very
important when you may be probing around in vacuum tube equipment and may
perhaps drop the probe or mistakenly connect it to the wrong test point.
Many of the other manufacturer's scopes are limited to 20 or 40 volts peak
on the inputs some as low as 5 volts.
