While the LabVIEW instrument driver for the A itself does not include ready-to-run example programs, there are three ready-to-run example programs available from www. You can control external devices such as microwave switches, attenuators, solenoids, and power relays. Though all of these examples are intended to serve as a starting point for the creation of a custom application, they may be used without modification to immediately control the Agilent A. Choose from 19different modules to define your own configuration. The A offers flexible choices for system control. This can help you determine when to begin or end an acquisition. Each palette represents a distinct category of instrument driver functions for programming the A.

Since peak detection is one of the analysis functions available in LabVIEW, we can easily add that functionality to our application. Sample code created with instrument driver functions.

Using these example programs as a starting point, it is possible to begin communicating with the Agilent A very quickly, eliminating the difficulties associated with starting a project from scratch.
You can buy what you need now and add to it or reconfigure it as your requirements change. High-performance unit provides low-cost alternative to PXI and VXI switch and measurement platforms If you use automated test equipment for design validation or manufacturing, you now have a cost-effective alternative to PXI and VXI test-system platforms.
Web browser interface shows settings at a glance and provides remote access and control Self-guiding front panel to configure, troubleshoot or view data Low EMI and efficient system cooling Heavy-duty cabling and connection options Rack mount options Relay counters help predict end-of-life In-rack calibration for reduced maintenance time DMM measurement accuracies include the switch for simple calculations Make system connections easily and quickly with simple, reliable connection options: The rugged instrument comes with a variety of system-ready features: Use the instrument driver VIs to define your custom application.
Three ready-to-run examples are available from Agilent for the A platform. When you wish to extend the capabilities of the examples or wish to start a new custom application, the set of LabVIEW functions installed with the instrument driver provide all the building blocks you will need. An instrument driver is a set of software routines that control a programmable instrument.
LabVIEW itself is a graphical development environment for creating flexible and scalable test, measurement, and control applications rapidly and at minimal cost. Your signals are switched to the right measurement device without compromising signal integrity. The most straightforward way to take advantage of the LabVIEW instrument driver is to run the example programs, which give the user a basic introduction to the programming flow for the driver.
It can be incorporated into a more powerful and user-defined virtual instrumentation solution by taking advantage of LabVIEW’s unique instrument control, analysis, and user interface features.
Use the A to route individual signals or monitor multiple signals over a specified period of time—monitor a single channel or multiple channels, set alarms, and identify irregularities. Each palette represents a distinct category of instrument driver functions for programming the A. Introduction to the A Instrument Driver An instrument driver is a set of software routines that control a programmable instrument.
34980A Multifunction Switch/Measure Mainframe and Modules
Each routine that composes the driver corresponds to a programmatic operation such as configuring, reading from, writing to, or triggering the instrument. Choose between different switch types and topologies with frequency ranges from DC to 20 GHz. Two instrument driver palettes are shown below, in Figure 2. Switch in different measurements with high-performance signal switching with no external signal conditioning required.
Choose from 19different modules to define your own configuration. LabVIEW can also be used to interface with a data management system, whether that consists of a simple spreadsheet file or a relational database.
Using the Agilent 34980A with LabVIEW
Easier signal routing with four 2-wire internal analog buses. The driver includes a full set of functional building blocks that can be used to create a completely custom A application in LabVIEW. It displays the acquired data on a front panel indicator not pictured.
LabVIEW is an industry-standard graphical programming environment that can be used to quickly and easily acquire, analyze, and present data from the A. The A handles system switching up to 20 GHz and provides basic measurements and system control. Assign a sequence, give it a name and then execute it with the name you created.
You can control external devices such as microwave switches, attenuators, solenoids, and power relays. And since you have four 2-wire buses, you can dedicate one bus for use with the internal DMM and use the other three buses for module extensions or additional signal routing between modules, reducing your wiring needs.
Though all of these examples are intended to serve as a starting point for the creation of a custom application, they may be used without modification to immediately control the Agilent A. Use the ready-to-run example programs for a simple measurement application with little development effort, or customize agklent to take advantage of the additional analysis and presentation capability of Agilnet.
