Q:

Using

the

tektronix

2445B

oscilloscope,

what

are

Q:

How

does

this

compare

to

the

measurements

taken

with

the

RAPIDS

system?

A:

The

RAPIDS

system

is

not

as

accurate

as

the

Tektronix

oscilloscope.

The

summed

wave

is

much

easier

to

read

on

the

RAPIDS

system.

The

following
