Measurement Event Synchronization
Measurement Event Synchronization
Description
Measurement event synchronization saves time by controlling the communication between the controller, the
test set, and the mobile station, so that no device does something before it is supposed to (which can cause
errors or do something well after it could have). Because some measurements can run concurrently, it is
necessary that the control program know when individual measurement results are available.
Measurement event synchronization is accomplished using the INITiate subsystem’s command
INITiate:DONE? or the STATus:OPERation:NMRReady status registers.
INITiate:DONE?
The INITiate:DONE? query returns a string that indicates what, if any, measurements are ready to be
fetched. This query should be used inside a loop, checking each measurement that was initiated. See
“INITiate:DONE?” on page 439 for more details about this query.
The INITiate:DONE? query returns at least one of the following indicators for each pass through the loop:
• "TXP" - The transmit power measurement results are available.
• "PVT" - The power versus time measurement results are available.
• "PFER" - The phase and frequency error measurement results are available.
• "FBER" - The fast bit error measurement results are available.*
• “BERR” - The bit error measurement results are available.*
• "AAUD" - The analog audio measurement results are available.*
• "DAUD" - The decoded audio measurement results are available.*
• "ORFS" - The output RF spectrum measurement results are available.
• "DPOW" - The dynamic power measurement results are available.*
• "IQT" - The I/Q Tuning measurement results are available.*
• "WAIT" - There are one or more measurements which are in the measuring state which are not excluded
from the query. See “INITiate:DONE:FLAG<measurement mnemonic>” on page 441. When WAIT is
returned at least one measurement is not ready to be fetched yet.
• "NONE" - There are no measurements currently in the measuring state. This assumes no measurements
have been excluded. See “INITiate:DONE:FLAG<measurement mnemonic>” on page 441. This indicates
that all measurements results are available or none have been initiated.
NOTE
The indicators marked with a * are not returned for GPRS as those measurements are not
available in that test application.
