The measurement could not be started because the configured RF input path was
not active. This problem may occur e.g. when a measurement is started in combined
signal path mode and the master application has not yet activated the input path. The
LEDs above the RF connectors indicate whether the input and output paths are
active.
●
17 (RF Level not Settled) / 18 (RF Frequency not Settled):
The measurement could not be started because the R&S CMW500 was not yet ready
to deliver stable results after a change of the input signal power / the input signal
frequency.
●
19 (Call not Established):
The measurement could not be started because no signaling connection to the DUT
was established.
●
20 (Call Type not Usable):
The measurement could not be started because the established signaling connection
had wrong properties.
●
21 (Call Lost):
The measurement was interrupted because the signaling connection to the DUT was
lost.
Error Indicators for Single Results
Some applications provide error indicators for single results, in addition to the common
reliability indicator. Single-value error indicators are retrieved using a CALCulate...?
Command.
e.g. CALCulate:GPRF:MEAS<i>:POWer:CURRent?
Response: 3, OK, OK, OK, OFL, OFL, OK, OK, OK (global reliability: 3 (for "Overdriven"),
8 power results in 8 power steps, 2 results overdriven)
The error indicator is one of the following values.
Returned value Meaning Description
OK OK Measurement result available, no error detected
ULEU User limit violation
upper
An upper limit is violated. The measurement result is above the
limit.
ULEL User limit violation
lower
A lower limit is violated. The measurement result is below the
limit.
OFL Overflow Measurement result available, however, the accuracy of the
result may be impaired because the input signal level was too
high
UFL Underflow Measurement result available, however, the accuracy of the
result may be impaired because the input signal level was too
low
INV Invalid Measurement was performed but a single result is invalid, e.g.
because it cannot be measured under the special conditions of
the measurement
NAV Not available No measurement result available, e. g. because the measure-
ment could not be started
