Performance Verification
This section contains procedures for checking that the ADA400A Differential
Preamplifier meets warranted specifications.
Requirements for Performance
The performance limits of this procedure are valid with the following conditions:
H
The ADA400A Differential Preamplifier is in an environment that is within
the operating limits of temperature, altitude, humidity, and vibration
described in
Specifications.
H
The data line jumper located inside the ADA400A Differential Preamplifier.
is properly configured depending on the type of oscilloscope you connect to
the output. See the
Installation
section on page 2.
H
The ADA400A Differential Preamplifier has a period of at least a 20 minutes
to warm up prior to verification.
Equipment Required
