The

following

information

describes

techniques

for

making

Waveform

measurements

featuring

the

cursor

function

of

the

5D10

Waveform

Digitizer.Basic

measurements

such

as

voltage,

pulse

width,

and

rise

and

fall

time

will

be

discussed

first,

followed

by

specific

measurement

techniques

including

stepper

motor

shaft

settling

time

measurement,

shock

and

vibration

measurements

and

color

plotting.These

procedures

provide

enough

detailtoenable

the

operator

to

adapt

them

to

other

related

Waveform

measurements

.
