www.vxitech.com VXIPLUG&PLAY COMMON FUNCTION CALLS Background The VX4330 is part of the SurePath family of switch cards. As such, a SurePath controller card is required to communicate to this device. The SurePath controller card is installed in either the leftmost switch card of a SurePath switching system or in a VX4101 MultiPaq instrument. If the SurePath controller card is installed in a SurePath family switch, all calls made to a SurePath switch card are made through tkvx43x0_32.dll.
VXI Technology, Inc. TABLE 11-19: TKVX43X0_32.
www.vxitech.com Exceptions 1.) tkvx43x0_powerFailure is not supported. If called, this function will return an error. The SM4330 uses non-latching relays and all relays will return to their default state if power is removed from the chassis. 2.) The VX4330 scanner is divided into 6 sections, while the SM4330 is divided into 16 sections. Since there is not a 1 - 1 mapping between the two cards, the SM4330 is limited to supporting the following two configurations using the _joinScanners function.

www.vxitech.com INTERFACING TO THE MODULE The DMM portion of the VTI4101A uses a 15-pin D-Sub style connector for front panel interfacing. There is a removable 2 A fuse for overcurrent protection. A mating connector is provided with the unit upon shipment. The Counter/Timer portion of the device uses five SMB style connectors for front panel interfacing. In many ATE applications, a termination panel for the instrumentation is utilized.

www.vxitech.com VXIPLUG&PLAY COMMON FUNCTION CALLS Background The VX4101A MultiPaq module combines several instrument functions in a single slot. The MultiPaq module includes a 5.5 digit DMM, 250 MHz Universal Counter Timer and an optional SurePath switch controller card. In addition, there are options for DAC's and digital I/O. The VMIP line of instrumentation offered by VXI Technology allows three independent instruments to be housed in a single slot carrier.
VXI Technology, Inc. TABLE 12-2: TKVX4101_32.
www.vxitech.com Exceptions (DMM) 1.) Fast data channel and asynchronous protocol functions are not supported in this driver set. Calls to these functions will return an error. 2.) If a multipaqWrite function is issued to anything but the counter, an instrument error will most likely occur. 3.) The translation driver set will emulate the Status functions as closely as possible. There may be instances where returned data does not completely match the response that would be received from a VX4101A.

VXI Technology, Inc. In the Tektronix SurePath family of switch modules, at least one SurePath controller card must be installed to ensure proper communications. The controller card may be installed in one of the switch modules, or it may be installed in the VX4101A MultiPaq device. If it is installed in one of the switch cards, the corresponding driver layer is the tkvx43x0_32.dll, which is addressed in the individual module sections.

VXI Technology, Inc. INTERFACING TO THE MODULE The SM73A308 has one 160-pin high density DIN connector on its front panel for I/O interfacing. Mating connector and pin part numbers are referenced below. These parts can be ordered directly from VXI Technology or the manufacturer listed in the table.

www.vxitech.com In many ATE applications, a termination panel for the instrumentation is utilized. This termination panel will have connectors that mate to the UUT or an intermediate test fixture. A termination panel may take the form of an Interconnect Assembly (ICA) made by manufacturers such as Virginia Panel or Macpanel. In either case, it is desirable to maintain the same I/O layout at the panel to avoid costly redesign of test fixturing or UUT cable assemblies.
