Invalid Measurement Results
Invalid Measurement Results
Description
Invalid measurement results are returned by the test set when conditions such as signal level are not within
the present measurement range. Three different invalid measurement results are provided in order to help
you understand the condition that caused the invalid result.
• 9.9E+37 = INFinity (Infinity)
• -9.9E+37 = NINF (Negative Infinity)
• 9.91E+37 = NAN (Not A Number)
9.9E+37 (INFinity)
9.9E+37 is returned by the test set when the measurement is out of range and results are far above the
present measurement range.
-9.9E+37 (NINFinity)
-9.91E+37 is returned by the test set when the measurement is out of range and results are far below the
present measurement range.
9.91E+37 (NAN)
9.91E+37 is returned by the test set when the measurement is out of range but it can not be determined if
measurement results are far above, or far below the measurement range.
If a measurement exceeds its measurement timeout value before a valid result is determined, 9.91E+37 is
returned.
FETCH? and READ? Invalid Results
When a FETCH? or READ? query is performed on a measurement with invalid results, the integrity indicator
returns a value of 1, indicating No Result Available.
Manual Users Invalid Results
Manual users will generally see four dashes , “----” on the test set display. When the measurement timeout
value has been exceeded, “Measurement Timeout” is displayed as well as the four dashes.
