Find and show SCPI Commands Context sensitive SCPI Commands Apart from the requested background information on a certain GUI parameter the SCPI command syntax is also shown. See chapter 3.2 on page 12 if certain indices and parameter values are needed in addition to the SCPI command syntax. Not only parameter related information but also technology (e.g. EUTRA/LTE) specific details can be requested that may have an impact on the overall SMW configuration. 3.2 Context sensitive SCPI Commands Additionally, the SCPI command syntax including the indices and parameter values can now be requested via the context sensitive menu for each GUI parameter. Thus the time consuming hunting for appropriate SCPI commands belongs definitely to the past. The shown SCPI command string can now directly be used in control software without further extensions and/or parameterization. The following example shows how to request the SCPI command to set the trigger mode for the ‘Custom Digital Modulation’ in ‘Baseband’ block A to single mode: 1 2 3 Figure 5: Show SCPI Command for certain Parameter Choose the parameter for the required SCPI command. Open the parameter specific context sensitive menu. Request the SCPI command. The displayed SCPI command can now be taken over manually into the test automation software or may be used to check the correctness of an already implemented code. It is advisable to use the SCPI command recording functions explained in detail in chapter 4 (starting at page 13), in case an SMW configuration has to be defined through numerous SCPI commands. 1GP98_0E Rohde & Schwarz SCPI-Recorder 12
SCPI List, Sequence and Script Generation Manual SCPI Sequence Recording 4 SCPI List, Sequence and Script Generation Additional functions are integrated in the SMW which allow generating SCPI lists and sequences for any signal generator configuration. These functions are tailored for different modes of operation. In the context of this application note a SCPI sequence consists of several SCPI commands in their chronological order of execution. A SCPI list in contrast comprises all SCPI commands needed for a certain functional setup of the signal generator but does not specify the mandatory or advisable order of their execution. 4.1 Manual SCPI Sequence Recording It is now possible to manually record a SCPI sequence consisting of SCPI commands comprising any number of parameter variations via the GUI. In this recording mode, the user has to decide deliberately for which parameter modification performed the related SCPI command shall be added to the SCPI sequence. The recorded sequence can be exported into a final step as a script file in various formats. This mode of recording is extremely helpful if a certain SMW configuration has to be worked out and thus not any parameter variation or key stroke but only the final and proper settings should be recorded. The following figure shows how the manual SCPI sequence recording is activated and how SCPI commands are then appended to the SCPI sequence: 1 Figure 6: Start manual SCPI Recording 1GP98_0E Rohde & Schwarz SCPI-Recorder 13
