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” on page 476 for more details about this query.
The INITiate:DONE? query returns at least one of the following indicators for each pass through the loop:
• "CPOW" - The channel power measurement results are available.
• "DAP” - The digital average power measurement results are available.
• "WQU" - The waveform quality 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 480. 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 480. This would
indicate that all measurements results are available or none have been initiated.
