Spectrum Master™ Programming Manual : 4 Measurement Commands : [:SENSe]:OTA Subsystem

[:SENSe]:OTA Subsystem
This subsystem includes commands used to set up parameters associated with Over the Air measurements.
OTA Reset
[:SENSe]:OTA:RESet
This command forces the instrument to reset the over-the-air measurement and start fresh without any history.
When the auto scrambling code feature is ON the RESet command will clear the list of scrambling codes and attempt to detect new codes.
When the auto scrambling code feature is OFF the RESet command will force the instrument to take new measurements for all of the user-selected scrambling codes.
 
OTA Scrambling Code
[:SENSe]:OTA:SCODe[1]|2|3|4|5|6 <scrambling code>
[:SENSe]:OTA:SCODe[1]|2|3|4|5|6?
This command refers to the primary scrambling codes used for W-CDMA over-the-air measurements. To disable the specified code use a scrambling code value of ‘-1’.
When the auto scrambling code feature is turned on, setting this value has no direct effect on measurement results.
 
Automatic OTA Scrambling Code Detection
[:SENSe]:OTA:SCODe:AUTO OFF|ON|0|1
[:SENSe]:OTA:SCODe:AUTO?
Sets the state of the automatic scrambling code detection feature.
Setting the value to ON or 1 will result in the scrambling codes being set to the codes of the strongest detected signals. That is, the instrument will detect the strongest signals present.
Setting the value to OFF or 0 will force the instrument to base all over-the-air measurements on the user-selected scrambling code values.
The default value is ON. That is, sending :SENS:DEM:OTA:SCOD:AUTO is equivalent to sending :SENS:DEM:OTA:SCOD:AUTO ON.
 
OTA Scrambling Code Lock
[:SENSe]:OTA:SCODe:LOCK OFF|ON|0|1
[:SENSe]:OTA:SCODe:LOCK?
This command refers to the primary scrambling codes used for W-CDMA over-the-air measurements.
When scrambling code lock is ON, the instrument will not search for any new scrambling codes and will only measure the codes that have already been detected.
When scrambling code lock is OFF, the instrument will dynamically update the list of scrambling codes that are to be included in the current measurements.
This feature has no effect when scrambling code auto detection is OFF for over-the-air measurements.
The default value for this command is ON. That is, sending SENS:DEM:OTA:LOCK is equivalent to SENS:DEM:OTA:LOCK ON.
 
OTA Sort Parameter
[:SENSe]:OTA:SORT CODE|POWer
[:SENSe]:OTA:SORT?
This command refers to the parameter that is used to sort the over-the-air measurement results.
 
PASS/FAIL Test Selection
[:SENSe]:PFail <test set>
[:SENSe]:PFail?
Selects the active test set to be used in subsequent PASS/FAIL measurements. The <test set> value must correspond to a test set that is defined in the test set list. For more information on loading test sets to the instrument, refer to the Anritsu Master Software Tools documentation. NOTE: The first test set in the list would be test set 0, the next test set would be 1, etc.
When using the query form of the command, the return value will be the currently selected test set number. If there is not a valid test set selected, the return value will be “-1” (negative 1).
