146 HP E1563A and E1564A Verification Tests
•
Ambient relative humidity of the test area is <80%.
•
Must have a one hour warm-up with all input signals removed before
verification or adjustment.
•
Use only copper connections to minimize thermal offset voltages.
•
Use shielded twisted Teflon
dielectric absorption cable for all measurements to reduce high resistance
errors.
•
Keep cables as short as possible. Long test leads can act as an antenna
causing the pick-up of ac signals and contributing to measurement error.
•
Allow 5 minutes after handling input connections for thermal offset voltage
settling.
Make copies of the Performance Test Record at the end of this chapter for use in
performance verifying each channel (use one test record copy per channel). The test
record provides space to enter the results of each Performance Verification test and
to compare the results with the upper and lower limits for the test.
The value in the "Measurement Uncertainty" column of the test record is derived
from the specifications of the source used for the test, and represents the expected
accuracy of the source. The value in the "Test Accuracy Ratio (TAR)" column of
the test record is the ratio of digitizer accuracy to measurement uncertainty.
Performance Verification Test programs are provided so you can performance
verify your digitizer. These programs were developed on a 486 IBM compatible
computer running Windows 3.1® with an HP 82341 HP-IB interface and HP SICL/
Windows 3.1® and Windows NT® for HP-IB software.
