In most sampling instruments I have encountered, signals start distorting when they
exceed about 2 volts in amplitude. Damage to the sampling diodes occurs around 5
volts and you never want to apply DC to the input of a sampler.
There are a couple of exceptions to this . . .

Hi,
I haven't had any experience with sampling CROs but believe the plugins can
be damaged with input signals greater than 5 to 10 volts (depending on model). Be
careful to limit input signals as they're very difficult to obtain parts or
service.
Perhaps others have some comments on this.
Good Luck, Don Black.

My opinion is that a working and calibrated 7S14 that meets all of its
original specifications should be worth $150. The problem is that almost
nobody has the ability to determine if one is really working properly or
not. You have to have a very fast rise and clean pulse generator, an
amplitude calibrated 50 ohm voltage source, and a fast time mark generator at
a very minimum in order to get any idea if it really works correctly.
If it does not work correctly, it may be impossible to find the parts you
need to fix it. The most vulnerable parts are the sampling diodes and I
suspect they are impossible to find, but I have to admit I have not searched
for any. I am sure there are other critical, hard to find parts in the 7S14.
Does this unit come with a "money-back guarantee" . . . ?

Hello!
I am in need of some info about the 7S14 plug-in... is it worth $150 in
operating condition?. How does it performs?
Please, any information will be welcomed.
Thanks!
