Integrity Indicator
trigger (late relative to a transmitted burst) the measurement sampling operation didn't start until after the
rising edge of the transmitted burst.
(10) Signal Too Noisy: Indicates that the measurement algorithm has found the signal measured to be too
noisy to provide accurate results.
(11) Sync Not Found: Indicates that the midamble was not found therefore the measurement was not
synchronized.
(12) Oven Out of Range: Indicates that a temperature controlled oven (other than the internal timebase oven)
is outside of its operating range. The power meter's oven is checked and its condition reported with this value.
(The internal timebase generates a temporary error message (out of lock) that is sent to the system error
queue and the display. This is not an integrity indicator value, it is an error message.)
(13) Unidentified Error: Indicates errors which are not covered by the other integrity values. Examples
include: parameter errors, algorithm memory errors (too many measurements), measurements unavailable
(unable to control), autorange unable to converge, default calibration data used.
(14) PCM Full Scale Warning: Indicates that the PCM signal has reached plus or minus full scale. The
measurement made will be accurate on the PCM signal but would typically indicate an overdriven or
oscillating element in the DUT.
(15) Questionable Result for PGSM: Indicates that the user attempted to make an FBER measurement in a
phase 1 system. FBER is only possible in a phase 2 GSM system. This indicator is available only when the
selected broadcast band is PGSM.
(16) Questionable Result Due To Channel Mode: Indicates that the channel mode was set to Enhanced Full
Rate Speech while a Decoded Audio measurement was active. Decoded Audio is not supported for EFR Speech.
Integrity Indicators verses Error Message
Error messages are divided into four classes: integrity errors, fatal errors, persistent errors, and
non-persistent errors.
Integrity indicator errors are 1 of 16 different messages that indicate if a measurement was valid.
Fatal errors consist of asserts and exceptions. Asserts occur when firmware encounters a condition that should
never occur. Exceptions occur when firmware attempts to access a memory location that is invalid.
Non-persistent occur errors if a condition exists that is incorrect but has no serious lasting effect on
instrument operation.
Persistent errors occur when hardware failures are found or when damage or injury to a person or the test set
may occur.
