Before beginning the procedures in this section, connect the output of the
ADA400A Differential Preamplifier to the oscilloscope, turn the oscilloscope on,
and let the ADA400A warm up for 20 minutes.
NOTE. Before performing these procedures, make sure your oscilloscope can
display the proper scale factor. If you are using an oscilloscope that is not
compatible with the scale factor coding of the ADA400A Differential Preamplifi-
er to perform these procedures, see page 2 to properly configure the scale factor
coding.
To convert the volts/division settings for oscilloscopes that cannot read the scale
factor from the ADA400A, multiply the volts/div setting in the procedure by the
gain setting of the ADA400A.
