Measurement Explanation and Suggestions Measurement Point
Instrument
Self-Test The HP-IB command, *TST?, is sent to the instru-
ment. The instrument responds with a result in
the range, 0 to 4094. If the result is not zero, then
one or more instrument self tests failed. Individual
bits in the result are set to 1 to indicate that certain
tests failed. The program decodes the bits that are
set and prints a message for each bit that is set to
1. The messages are listed below. See Descrip-
tion of Self-Test Diagnostic earlier in this chapter.
