PXI instruments later on when installed in your system. The applet configuration is saved to PXISYS.ini and PXIeSYS.ini that are used by Marvin Test Solutions instruments, the VISA provider and VISA based instruments drivers. In addition, the applet can be used to assign chassis numbers, Legacy Slot numbers and instruments alias names. -
Page 20: Configuring Your Pxi System Using The Pxi/Pci Explorer
Legacy slots numbers are used by older Marvin Test Solutions or VISA drivers. Alias names can provide a way to address a PXI device using your logical name (e.g. “DIO1”). For more information regarding these numbers see the DioSetupInitialization and DioSetupInitializationVisa functions in the DIO Programming User’s Guide. -

Page 23: Plug & Play Driver Installation
Chapter 3 - Installation and Setup Carefully slide the PXI board to the rear of the chassis, make sure that the ejector handles are pushed out (as shown in Figure 3-3). Figure 3-3: Ejector handles position during module insertion After you feel resistance, push in the ejector handles as shown in Figure 3-4 to secure the module into the frame. - Page 24 GX5280 User Guide If another Marvin Test Solutions board software package was already installed, Windows will suggest using the driver information file: HW.INF. The file is located in your Program Files\Marvin Test Solutions\HW folder. Click Next to confirm and follow the instructions on the screen to complete the driver installation.

Page 25: Removing A Board
Chapter 3 - Installation and Setup Removing a Board Remove the board as follows: Turn off the PXI chassis and unplug the power cord. Locate a PXI slot on the PXI chassis. Disconnect and remove any cables/connectors connected to the board. Un-tighten the module’s front panel screws to the chassis. - Page 26 GX5280 User Guide...

Page 27: Chapter 4 - Theory Of Operation
Chapter 4 - Theory of Operation This chapter presents the theory of operation for the GX5280 boards, with an overview of operation and a simple description of operation for one channel (I/O pin). Other topics covered in this chapter are: ... -
Page 28: Masters And Slaves
The Master distributes clock, control and status signals to all the Slaves in the domain through the PXI Bus. Any GX5280 board can be a Master or a Slave depends on the on-board switch settings (see Chapter 3). Although Master/Slave transformation can only be done when the system is shutdown. -

Chapter 4 - Theory of Operation Figure 4-2: I/O Channel Block Diagram Channel is set to be in output mode The Channel’s Direction control is set to output through software enabling the Out Buffer and disables the In Buffer. At the Out Buffer output there is an Output Enable Driver that is controlled by software. The output signal is then being fed into two buffers: Programmable Voltage Level Buffer and LVDS Buffer. -

100MHz. Similarly, the strobe signal latches the input vector. All clock and strobe signals are distributed to all DIOs. The GX5280’s clock architecture provides the user with the flexibility to align signals between the DIO and the Unit Under Test (UUT) using delay settings. Figure 4-3 is a block diagram of the clock architecture which includes programmable delays for the DIO clock and strobe. -
