Syntax :CALCulate<n>:DATA<m>:EDIagram?
Description Query the eye scan measurement data.
This command can only be run after :CALCulate<n>:DATA<m>:EDIagram:STATus?
command has returned COMPLETE.
Parameters No parameters
Response The eye scan data points in a comma separated array. The format of the data is
<number_of_rows>,<number_of_columns>,<points[0][0]>, .. , <points[number_of_rows-
1][number_of_columns-1]>"
The number of rows and columns depends on your eye scan settings.
Example :CALCulate3:DATA2:EDIagram? -> "63,63,<array of 63*63 points>"
Command :CALCulate<n>:DATA<m>:EDIagram:STATus?
Syntax :CALCulate<n>:DATA<m>:EDIagram:STATus?[<wsp><INFO>]
Description Query the eye scan measurement status.
Parameters INFO: Provides a description of what the return values represent
Response The current status of the eye scan measurement.
-1 | STOPPED: There is no data as the scan has been cancelled or is not started
0 | RUNNING: The scan has been started and is still sampling data
1 | COMPLETE: The scan is complete, and all data is available
Example :CALCulate3:DATA2:EDIagram:STATus? -> -1
:CALCulate3:DATA2:EDIagram:STATus? INFO ->
-1:STOPPED
0:RUNNING
1:COMPLETE
Command :CALCulate<n>:DATA<m>:BATHtub?
Syntax :CALCulate<n>:DATA<m>:BATHtub?
Description Query the BER values from the bathtub measurement
Parameters No parameters
Response A comma separated string of values, in the format <number of points>, <phase set
points>, <measured BER>, <extrapolated BER>
The first value in the comma separated string of values is the number of points, the
next <number of points> values are the phase set points, the next <number of points>
values are the measured BER, and the final <number of points> values are the
extrapolated BER.
Example :CALCulate3:DATA2:BATHtub? -> 317,-4.9375000e-01,-4.9062500e-01,-
4.8750000e-01,-4.8437500e-01,-4.8125000e-01,-4.7812500e-01,
4.7500000e-01......
Command :CALCulate<n>:DATA<m>:BATHtub:STATus?
Syntax :CALCulate<n>:DATA<m>:BATHtub:STATus?[<wsp><INFO>]
Description Query the status of the bathtub measurement.
Parameters INFO: Provides a description of what the return values represent
Response The current status of the bathtub measurement.
-1 | INVALID: The bathtub measurement has not been run.
0 | RUNNING: The scan has been started and is currently sampling data.
1 | STOPPED (USER): The scan was stopped by the user and all data is available
2 | STOPPED (AUTO): The scan detected a loss of data and exited the bathtub scan.
3 | INVALID SIGNAL: The input data is not recognized. The bathtub cannot start.
Example :CALCulate3:DATA2:BATHtub:STATus? -> -1
:CALCulate3:DATA2:BATHtub:STATus? INFO ->
-1:INVALID
0:RUNNING
1:STOPPED (USER)
2:STOPPED (AUTO)
3:INVALID SIGNAL
Command :CALCulate<n>:DATA<m>:BATHtub:ELAPsed?
