In addition, the contains latching electromechanical relays that enable signal bandwidths of up to 50 MHz. Next, assign a measurementfunction to a channel or a group of channels. Do all this from two menus and see – on one screen – how each channel is configured. Furthermore, a channel can be programmed for enhanced measurement features to address requirements for tighter tolerance or higher speed. Data can be viewed in a table or displayed on a plot without interrupting an automated scan sequence.
Of most importance, there is no lost test time due to the instrument sitting idle following a power outage. In fact, the DAQ can execute an automated sequence entirely without a PC thus saving test kwithley and reducing the capital cost of the system.
Using a 4-wire RTD, temperature can be measured with with an excellent 2-year accuracy of 0. There are additional optional parameters to jeithley the measurements and the switching to meet a specific application. Build a Keithley DAQ test system with a selection of 12 plug-in switch modules with a wide range of functionality. To test channels during setup, manually close channels on the setup screen.
NEW Data Sheet 3. 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 dual functionality enables maximized utilization of your instrument.
There are two additional protected channels for current measurements. These test scripts are complete test programs based on an easy-to-use yet 77700 efficient and compact scripting language, LUA www.
Use the DAQ with its front panel terminals to troubleshoot a test setup, a circuit, or to verify the value of a component. The touchscreen, graphic display shows the channel setup and the measurement programmed for each channel. The measurement on that channel is displayed next to the closed channel. Use a TSP script and the TSP-Link interface to execute a test for instrument-to-instrument communication without interaction with a computer.
Thus, channel performance can be verified during set up or debugged if the measurement is out of the expected range before the test is executed. The status screen shows the percentage of the test that has been completed, the number of scans that have been completed, measurements on channels selected for monitoring, and whether any measurements are out of range. Thus, for most applications, the calibration cycle for the DAQ can be two years.
Providing the finest test equipment solutions since 1992
TSP scripting allows running powerful test scripts directly on the instrument, without the need for an external PC controller. Low resistance readings can be improved with a thermal offset compensation measurement technique. Use the scan status, swipe screen to continuously monitor channels. Data can be stored to an external USB memory stick to prevent data loss in the event of interruption of line power. Kickstart also includes comparison tools to allow you to plot and overlay data from the run history of each test.
Using the TSP language to create a script, kdithley user can display messages for an operator in an automated or a semi-automated test system.

The Status screen will display an out-of-limit indication when any channel’s measurement is outside the channel’s limit settings. 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. A quick view of the display can give an indication of the status of the test at any time during the test.
The is ideal for RTD, thermistor, and thermocouple temperature applications.
For example, the DAQ can send commands to a temperature chamber to operate at specific temperatures and execute a scan when the chamber has reached the programmed temperatures.
Two-year accuracy specifications are included, so you can be assured your critical measurements remain accurate and fully traceable. TSP technology also offers mainframe-less channel expansion.
KickStart allows you to configure, test, and collect data from multiple instruments, including DMMs, power supplies, SMU instruments, and dataloggers. Want to review the trend of the data?
Even switch signals from wireless devices with RF modules having a maximum switching frequency of 3.
keitgley Test scripts can contain any 7700 of routines that are executable by conventional krithley 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.
The system is organized in a master-subordinate configuration, essentially allowing the connected instruments to act as one. 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.
All these measurement functions can be used with the various plug-in switch modules. The chart below shows all of the DAQ’s 15 measurement functions and kkeithley. For maximum accuracy, measurements can be filtered and integrated over a range of time intervals. 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.
Thus, when relay switch closures approach the manufacturers’ relay life specification, the switch card module can be replaced during scheduled maintenance. Thus, the DAQ with its 12 switch modules provides an extensive range of flexibility to build a wide range of data acquisition or test systems.
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. The DAQ has keithpey built-in intelligence to execute a test script, make decisions, and keithly other instruments. The D-sub connectors minimize downtime when changing plug-in switch modules during system maintenance or during the setup of a new test system. If main power is lost, the Keithley DAQ will re-start the scan when the power is restored.
Also measure other parameters in addition to temperature.
