The Benchtop Chassis is designed to be used as part of a TLA 700 Series Logic Analyzer. It is an intelligent, 13-slot chassis with the following features: High output power supply Intelligent cooling for installed modules High quality auto-configurable backplane Optional adjustable rackmounts Standard features are explained in more detail in the following paragraphs. Refer to the Options chapter for a description of optional features. Power Supply The Benchtop Chassis provides voltages at levels sufficient for the most demanding TLA 700 Series applications. The power supply has a volt-ampere capacity of 1660 VA with 872 watts usable by TLA 700 Series instrument modules at any one time. The chassis accommodates exclusively digital applications (using the logic analyzer module), exclusively analog applications (using the DSO module), or combinations of both. The power supply plugs directly into the rear of the chassis and has no cables to disconnect. Because of this design, you can replace the power supply in less than three minutes, keeping downtime to a minimum. The power supply automatically accommodates the appropriate input voltage and frequency; no mechanical switch is required to select the correct line voltage. Intelligent Cooling The Benchtop Chassis provides optimal cooling for all installed modules. The chassis uses an intelligent, adaptive cooling scheme to efficiently remove heat while maintaining quiet operation. When you set the blower to variable speed (default), the chassis automatically adjusts the blower speed to keep the temperature rise above the modules to approximately 10° C, or less. Using a rear panel switch, you can set the blower to full speed to provide maximum cooling at all times. Air is exhausted at the sides of the chassis allowing you to stack the chassis with other rackmount equipment. You don’t have to to worry about restricting any airflow out of the top of the chassis or creating a chimney effect. Cooling is not wasted on empty slots. Card guides automatically direct air to only those slots containing modules; empty slots are shut off. The chassis directs airflow across each installed module from the bottom to the top of each slot. Baffles balance the airflow from the front to back and across occupied slots in the chassis. You can replace the blower without disassembling the entire chassis. Backplane The Benchtop Chassis has an autoconfigurable, solid-state backplane that uses electronic jumpering of the IACK and BUS GRANT signal lines. There are no jumpers to move or install on the backplane. This results in a high quality backplane that is ideal for automatic test environment systems that must be reconfigured frequently. Full differential distribution of the CLK10 signals provide a clean timing source for your TLA 700 Series instruments.
