 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

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.
