P6701B and P6703B Performance Verification
Use the following procedures to verify the warranted specifications of the
P6701B and P6703B O/E converters. Before beginning these procedures, refer to
page 12 and photocopy the test record and use it to record the performance test
results. The recommended calibration interval is one year.
These procedures test the following specifications:
H Noise equivalent power
H Output zero
H DC conversion gain
H AC conversion gain
Equipment Required
Table 7 lists the equipment required to perform the performance verification
procedure. The types and quantities of connectors may vary depending on the
specific equipment you use.
The instrument should be given a 20 minute warm up period and ambient
temperature must be between 20 and 30 degrees C.
