7 Theory of Operation
7.1 DC Gain (Voltage or Current) Test
General information
Required equipment:
l
DC reference
l
Multimeter (DVM)
(Only required when the accuracy of the DC reference is not adequate).
Acquisition settings:
l
Maximum sample rate
l
All channels DC
-
coupled
l
Mode
-
, Filter
-
and Range settings as defined by the verification process.
HINT/TIP
The standard DC gain process uses a selected set of all Mode Filter and Range
settings supported by the
D evice U nder T est (DUT). The selection is done
based on the technical design of the DUT to ensure all design combinations
are tested.
Procedure:
Six voltages are input one at a time, using the DC reference. These voltages
are equally divided from
-
45 % of Range to +45 % of Range.
Each of the six voltages are stored and denoted as Vin
i
For each applied voltage an average value is calculated.
l
For sample rates < 10 MS/s 100 k samples are averaged.
l
For sample rates
≥
10 MS/s 10 M samples are averaged.
Each averaged value is denoted as Vmeas
