The 2750 is a switch mainframe from Keithley.
Additional Features:
Applications:
Precision low ohms multichannel measurements on materials, devices, components, and systems, including:
The Keithley 2750’s flexible, five-slot mainframe combines a 61⁄2-digit, 14-function DMM with support for up to 200 channels of two-pole switching and multi-channel analog/digital I/O control. This tight integration simplifies system design while it minimizes rack space requirements. It also allows the Model 2750 to scan and measure more than 200 channels per second, ensuring shorter test times and greater productivity than competitive approaches. Currently, the Model 2750 supports twelve optional plug-in switch/control modules and additional modules are already in development. Up to five modules can be mixed or matched to provide the combination of switching and control capabilities today’s ATE and data acquisition systems demand. For the flexibility needed for tomorrow’s applications, the Model 2750’s on-board flash memory can be reprogrammed to support new Keithley modules as they are introduced.

Built-in measurement functions include:
The Keithley Integra Series systems 2750 combines precision measurement, switching, and control in a single, tightly integrated enclosure for either rack-mounted or benchtop applications. These cost-effective, high performance test platforms offer affordable alternatives to separate DMMs and switch systems, dataloggers/ recorders, plug-in card data acquisition equipment, and VXI/PXI systems. The Integra Series plug-in switching and control modules offer unmatched flexibility and testing efficiency for a wide range of industries and applications.
System builders can create test solutions with a combination of channel count, cost per channel, and system performance unmatched by any other single-box measurement system. The input modules provide the flexibility to vary the channel count from 20 to 200 (2-pole), apply a stimulus to the device under test, route signals, control system components, and make precision measurements with up to 14 functions. Robust digital I/O capabilities can be used for triggering, handshaking with other automation equipment, and alarm limit outputs. Scan rates of up to 500 channels/second (up to 3500 readings/second on a single channel) will increase test productivity.
The Integra systems are fully integrated, off-the-shelf measurement and control systems. Their DMMlike interfaces make it easy for users to collect data and/or perform troubleshooting within minutes of installation and startup. Once sensor or DUT leads are hooked to the instrument’s input, use the front panel controls to select the measurement function, range, filtering, scaling, trigger source, scanning sequence, alarms, and more. The free ExceLINX-1A software makes it easy to configure and use the system in a graphical “point-and-click” environment. This gives developers the basic tools needed to create a simple application without writing program code.
The Integra systems offer a variety of advantages over existing solutions for ATE and data acquisition applications. For example, their flexible modular architecture and integrated measurement, switching, and control capabilities save rack space by reducing the number of separate instruments needed. This design also simplifies expanding the system as the number of channels grows or re-purposing it as new test requirements evolve. Integrated signal conditioning, scaling, stimulus, filtering and I/O capabilities eliminate the need for external circuitry when designing and building data acquisition systems. The Integra systems offer accuracy and repeatability superior to plug-in data acquisition boards, while providing faster test times than typical DMM/switch systems. This makes it possible to combine higher test yields with higher test throughput.
Integra Series mainframes support three major types of temperature sensors with built-in signal conditioning and 300V isolation: thermocouples, RTDs, and thermistors. To begin using a sensor, simply hook it up and the instrument does the rest. If a thermocouple is broken or disconnected, the instrument will alert the operator. The mainframes also support three methods for cold-junction compensation (CJC): automatic (built-in), external (built-in), and simulated.
Install up to five input modules in the 2750 mainframe (or up to two in the 2700 and 2701 mainframes). All switch/control modules are fully enclosed in impact-resistant plastic for exceptional ruggedness. Three connector alternatives simplify connecting the modules to DUTs. Rugged D-sub connectors allow quick, secure connections and are especially convenient when performing routine maintenance or when the system is installed in a rack. IDC ribbon cable adapters are supplied with the Model 7701, 7707, and 7709 modules for fast, uncomplicated hookups in production test and process monitoring applications. Oversize screw-terminal connectors simplify setup in applications that require the greatest connection flexibility. Additional D-sub and IDC ribbon cable connector kits and pre-wired cable assemblies are sold separately.
