Noise Test
General information
Required equipment:
l
50 Ohm termination plug
Acquisition settings:
l
Maximum sample rate
l
All channels are terminate together with a single external 50 Ohm plug
l
Mode
-
, Filter
-
and Range settings as defined by the verification process.
HINT/TIP
The noise test uses a selected set of all Mode Filter and Range settings
supported by the
D
evice
U
nder
T
est (DUT). Typically in one filter setting all
ranges are tested where all other filter settings are only tested in reduced range
settings as the filters used are range independent.
Procedure:
For each test setting 4000 samples are taken.
The standard deviation of this data is then calculated,
Vmeas
std
Noise
rms
=
Vmeas
std
/ Range * 100 %
