A number of modules have cold junction compensation, temperature references for thermocouple temperature monitoring of devices during environmental testing, and HALT and HASS accelerated life testing.

One option eases the identification of channels by allowing the creation of a name for each channel. Also save test time by reducing communication with the test controller. Also measure other parameters in addition to temperature.

If main power is lost, the Keithley DAQ will re-start the scan when the power is restored.

You can control up to eight instruments at the same time and retrieve millions of readings from each instrument.

Thus, for most applications, the calibration cycle for the DAQ can be two years. Test scripts can contain any sequence of routines that are executable by conventional programming languages including decision-making algorithmsso the instrument can manage every facet of the test without the need to communicate with a PC for decision making.

Automatic CJC is provided so that no other accessories are required to make thermocouple temperature measurements. This channel expansion bus allows connecting multiple DMM’s, other TSP-enabled instruments, and any LAN-based instruments together to form a tightly-synchronized instrument system.

The DAQ has the built-in intelligence to execute a test script, make decisions, and control other instruments. The Series plug-in module offers 20 channels of 2-pole or 10 channels of 4-pole multiplexer switching that can be configured as two independent banks of multiplexers. Connection is provided with simple low cost Category 5 Ethernet cabling. The new data will be stored in a separate data buffer with time-stamped measured data so that the lost time due to the power failure can be noted.


Build a test sequence and define the required measurements from one setup screen.

This can significantly change the way information is displayed or even automated while keifhley a test. This allows you to create powerful measurement applications without an integrated development environment IDE. Getting insights quickly is important, so KickStart plots your data immediately and dedicates a large portion of the viewing area to the graph, while also allowing you to view and edit the most essential parameters of other instruments in your test setup.

In addition keithlet an indication of measurements in an overflow condition, limit settings can be programmed for any channel.

To test channels during setup, manually close channels on the setup screen.

Data can be stored to an external USB memory stick to prevent data loss in the event of interruption of line power. The dual functionality enables maximized utilization of your instrument. A quick view of the display can give an indication of the status of the test at any time during the test.

Unplanned system downtime results in loss of productivity and delayed product shipments or loss of valuable development time during product audit testing, accelerated life testing, and environmental testing. TSPLink technology supports up to 32 instruments, so it’s easy to scale a system to fit the requirements of an application. Thus, when relay switch closures approach the manufacturers’ relay life specification, the switch card module can be replaced during scheduled maintenance.

Data can be viewed in a table or displayed on a plot without interrupting an automated scan sequence. The touchscreen, graphic display shows the channel setup and the measurement programmed for each channel.

For example, measure the temperature of devices in an environmental chamber with thermocouples using the plug-in switch modules that have automatic cold reference junction compensation for thermocouple measurements. Save bench space and cost with an instrument that performs like a DMM and a data logger.


The measurement on that channel is displayed next to the closed channel. Of most importance, there is no lost test time due to the instrument sitting idle following a power outage. Then define both the time interval between measurements and scans if multiple scans are required.

These examples highlight the unique ability of the Keithley DAQ to run specialized applications that customize the user interface. Never lose time with a test in which a problem such as a broken wire, a mis-wired connection, or a defective DUT can invalidate days of data. Kickstart also includes comparison tools to allow you to plot and overlay data from the run history of each test.

Providing the finest test equipment solutions since 1992

The Keithley DAQ is specified for both 1-year and 2-year accuracy specifications with little difference between the 1-year and 2-year specifications. A large 5-inch You can choose the interface that is most suitable for your needs.

The DAQ also has an option to automatically restart scanning after a power interruption. With 12 plug-in switching and control modules available and two module slots, you can build a test system that can measure or control up to 80 devices-under-test DUTs in a multiplexing configuration.

The chart below shows all of the DAQ’s 15 measurement functions and ranges. Using the TSP language to create a script, the user can display messages for an operator in an automated or a semi-automated test system.

Want to review the trend of the data? Use the DAQ with its front panel terminals to troubleshoot a test setup, a circuit, or to verify the value of a component.

Add customized applications to the DAQ to enhance the instrument’s capability.

Furthermore, a channel can be programmed for enhanced measurement features to address requirements for tighter tolerance or higher speed.
