After restarting your LabVIEW development environment the driver will then be directly accessible from the Instrument Driver function palette menu. Figure 1: Path to LabVIEW instrument driver in the function palette of the Block Diagram 1.2 LabVIEW Settings For optimal usage please turn off "Synchronize with directory" feature on Instrument Drivers palette before installing any Rohde & Schwarz LabVIEW driver. If this feature is turned on, it overwrites driverвЂ™s palette files with its own. Rohde & Schwarz How to use the RsSpecAn Driver for R&SВ®Spectrum Analyzers and R&SВ®ESL EMI Test Receiver 3 LabVIEW LabVIEW Settings 1.2.1 LabVIEW 8.x Turn off "Synchronize with directory" feature: Tools => Advanced => Edit palette set. Then find "Instrument I/O" palette Right click on it and clear checkbox besides Synchronize with directory in context menu and save the changes. Figure 2: Turn off вЂњSynchronize with directoryвЂќ feature in LabView 8.x 1.2.2 LabVIEW 7 Turn off "Synchronize with directory" feature: Tools => Advanced => Edit palette views.

Each VIs help is linked to the section in the help file that describes all the features of the VI. An additional help topic can be accessed directly by pressing "Click here for more help" in the Context Help of LabVIEW. 1.4 LabVIEW 7.1 driver Please use the LabVIEW 7 driver. 1.5 LabVIEW 8.x Please use the LabVIEW 8 driver. 1.6 How to use Attributes in LabVIEW? The new generation of Rohde & Schwarz' attribute-based instrument drivers gives great flexibility and ease of use by combining low-level access to nearly every SCPI command via attribute and well balanced high level functions and VIs, combining several attributes. For those who don't want to learn new attribute concept, complete functionality of instrument is covered by high level commands. In other words, you may use attributes, but you don't have to. Of course it is possible to combine both low level attributes and high level functions together exactly according to needs of every specific application. The following chapter shows how to use attributes in the RsSpecAn driver. This is only necessary in rare cases, for instance if the driver is not supporting the functionality via high level API. Example: How to set the Frequency Start value by attributes To select an attribute use the provided Express VI, included in instrument driver package. This instrument driver Express VI can be found in: User Libraries => Express User Libraries => rsspecan Rohde & Schwarz How to use the RsSpecAn Driver for R&SВ®Spectrum Analyzers and R&SВ®ESL EMI Test Receiver 5 LabVIEW How to use Attributes in LabVIEW? Figure 4: Palette Menu of RsSpecAn driver Drag and drop the rsspecan Attribute in your block diagram. After placing the express VI the front panel of the Express VI will be opened (see Figure below) Figure 5: Front panel of rsspecan_core_attribute_express Source.vi Now you can select the desired attribute from tree structured list. Each attribute can have different access type (read only, write only or read/write). Proper read/write operation can be selected by "Attribute Operation" in the bottom left corner. Repeated capabilities are set by using a string control at the bottom of the panel called "Repeated Capabilities". The attribute value is entered using standard LabVIEW controls for each data type (numeric, boolean, string or ring). Rohde & Schwarz How to use the RsSpecAn Driver for R&SВ®Spectrum Analyzers and R&SВ®ESL EMI Test Receiver 6 LabVIEW How to use Attributes in LabVIEW? For example use in Basic operation "Set Frequency Start" value: Figure 6: Configure "Set Frequency Start" example 1. Select the desired attribute. To find the designated attribute easily the rsspecan.chm help file can be used to look for it. Be aware of the fact that the tree structures in the help file and the Express VI are the same 2. Leave "Repeated Capabilities" empty 3. Type the desired frequency value in the text box "Value" 4. After clicking the "OK" button, a new instance attributed based VI is generated. The name of the VI, predefined values and the help is also adapted. The result is shown in following figure. Rohde & Schwarz How to use the RsSpecAn Driver for R&SВ®Spectrum Analyzers and R&SВ®ESL EMI Test Receiver 7 LabVIEW How to use Attributes in LabVIEW? Figure 7: Instanced attribute based VI "Set Frequency Start" The attribute and its features can be changed any time later by double clicking the VI, which recalls Express VIs front panel. 1.6.1 Repeated Capabilities Many instruments have capabilities which are duplicated. For example, an oscilloscope might have several channels with identical functionality or a power supply may have several outputs. For this reason repeated capabilities are introduced. Repeated capability instances are specified by a string parameter for each property. It also can be specified by a function which selects the active instance. To define the usage of particular capability fill the text box "Repeated Capability" in the front panel of the Express VI with the proper value. To use more than one repeated capability in one attribute separate them with a comma. See a marker example using repeated capabilities pictured in the following figure: Rohde & Schwarz How to use the RsSpecAn Driver for R&SВ®Spectrum Analyzers and R&SВ®ESL EMI Test Receiver 8 LabVIEW How to use Attributes in LabVIEW?

In addition the instrument driver documentation is also included in compressed HTML format (Windows CHM help file) and stored together with the driver sources.

The following chapter shows how to use attributes in the RsSpecAn driver. This is only necessary in rare cases, for instance if the driver is not supporting the functionality via high level API. Note: The rsspecan.sub file has to be added to the project. This is mandatory for browsing attributes. Example: How to set the Frequency Start value by attributes To select an attribute use the provided function panels, included in instrument driver package. This instrument driver function panels can be found in: Instruments=>R&S SpecAn=>Configuration=>Set/Get/Check Attribute/Repeated Capabilities Figure 9: Function panel for RsSpecAn driver attributes To open the function panel double click on the desired function. In the figure below the function panel of "rsspecan_SetAttributeViReal64" is pictured. By clicking on text box "'Attribute ID" the "Select Attribute Constant" window will be opened. Rohde & Schwarz How to use the RsSpecAn Driver for R&SВ®Spectrum Analyzers and R&SВ®ESL EMI Test Receiver 11 LabWindows/CVI How to use Attributes in LabWindows/CVI? Now you can select the desired attribute from tree structured list. Each attribute can have different access type (read only, write only or read/write). Proper read/write operation can be selected by selection the proper function panel, either Set Attribute, Get Attribute, or Check Attribute. Repeated capabilities are set by using identifier or identifier names within the function panel called rsspecan_GetAttributeRepeatedCapabilityId[s|Names]. For example use in Basic operation "Set Frequency Start" value: Figure 10: How to select a attribute in the "SetAttributeViReal64" function panel 1. Select the desired attribute. To find the designated attribute easily the rsspecan.chm help file can be used to look for it. Be aware of the fact that the tree structures in the help file and the Express VI are the same 2. Leave "Repeated Capabilities" string empty 3. Type the desired frequency value in the text box "Attribute Value", e.g. "1e+9" 4. Enter a valid instrument handle in the text box "Instrument Handle" 5. Optional you also can catch the return value of your function, if you type the name of a declared integer variable in the text box "Status" 6. To include the function into your source code, you can copy the created function string out of the window on the button of the function panel and insert it into the source code.
