TDS configuration requirements: The iView™ cable does not fully connect to the TDS1000/2000 Series oscilloscopes without a GPIB extender. Tektronix recommends a standard GPIB cable as an extender, or order a cable extender (National Instruments part number 181638-1). TDS2CMAX Communications Extension Module is required for iView capability on any TDS1000/2000 Series. TDS3GM GPIB/RS232 Interface Module required for iView capability on any TDS3000 series. TDS3GV GPIB/RS232/VGA Interface Module required for iView capability on any TDS3000B series. If using TLA7Axx iConnect with a TDS6404, TDS6604, TDS7154, TDS7404, CSA7154 or CSA7404 oscilloscope, four TCA-BNC connectors are required to be compatible with BNC cables from the TLA7Axx module.

The TLA721 mainframe is a  modular mainframe that accept TLA7Axx and TLA7Lx/Mx/Nx/Px/Qx logic analyzer modules, as well as TLA7PG2 pattern generator modules. The TLA721 can be used in conjunction with a TLA7XM expansion mainframe to provide solutions for large numbers of buses and high channel count requirements.

The TLA721 mainframe is built on a Microsoft® Windows® 2000 Professional PC platform that offers a familiar work environment. TLA applications operate like any other PC application.

The TLA721 mainframe comes standard with dual display capability for extended desktop viewing, in addition to an internal CD-RW, hard disk and PC card slots for expansion. A replaceable hard disk is standard on both mainframes, ideal for security or enabling individual team members to store personal setups and data. Trigger in/out connections provide an interface to other external instrumentation, such as TDS oscilloscopes, for correlating measurement results.
