Both the benchtop mainframe and the expansion mainframes are basically identical with the exception of the controllers. The benchtop mainframe includes a PC controller that controls the entire instrument. The expansion mainframe includes an expansion module that expands the capabilities of a benchtop mainframe or a TLA715 Portable Mainframe. Each mainframe can function as a logic analyzer, a digital storage oscilloscope, or a pattern generator, depending on the module cards installed in its slots. Benchtop Mainframe The benchtop mainframe comprises of a benchtop chassis and the benchtop controller. The benchtop controller is a Pentium III based, three-wide, C-size, embedded Slot-0 Controller that incorporates the same controller as the TLA715 Portable Mainframe. The benchtop chassis is based on the high power, 13-slot, VX1420A Mainframe without a readout and with additional labels. The benchtop mainframe has the following key features: Microsoft Windows operating system Ten slots (excluding three slots for the benchtop controller) for compatibility with new and existing LA, DSO, and patgen modules Personal computer (PC) based processor architecture that provides a cost effective, high-performance, system controller with automatic “PC connectivity” to a multitude off-the-shelf devices (such as Ethernet, modem, printers) via standard PC I/O ports and two PC card (CardBus) slots High-performance PC-based display system capable of driving large, high-resolution, external monitors in multiple user selected formats via an external SVGA port Easy configuration of modules between slots and mainframes through the automatic system configuration support of the resource manager and application software Precision clock, trigger line, and event signaling between the mainframe and modules for real-time triggering, sequencing, and correlation of events Easy access to field replaceable units (FRUs) to provide a low mean-time-to- repair (MTTR) for exchange modules Fan airflow capacity to support a reduction in audible noise levels Mainframe compatible with international power standards, certified to international safety and EMC requirements, and tested to rugged environ- mental standards 100% hardware and software compatibility with the TLA715 Portable Mainframe, allowing you to transport modules, data, and end-user application programs between mainframes Expansion Mainframe The expansion mainframe comprises of a benchtop chassis and the expansion module. The expansion module is a single-wide, C-size, modules that provides cable connections to a benchtop mainframe or to a portable mainframe. The expansion mainframe has the following key features: Microsoft Windows operating system 12 slots (excluding one slot for the expansion module) for compatibility with new and existing LA, DSO, and patgen modules Precision clock, trigger line, and event signaling between the mainframe and modules for real-time triggering, sequencing, and correlation of events Easy access to field replaceable units (FRUs) to provide a low mean-time-to- repair (MTTR) for exchange modules Fan airflow capacity to support a reduction in audible noise levels Mainframe compatible with international power standards, certified to international safety and EMC requirements, and tested to rugged environmental standards
