Used Keithley Instruments 20 Channel Multiplexer Card | MATsolutions
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. Its factory-installed applications that allow the creation of a modified display to show data from multiple channels; and report plug-in module relay closure counts that enable determination of when a plug-in module needs to be replaced.
Thus, when relay switch closures approach the manufacturers’ relay life specification, the switch card module can be replaced during scheduled maintenance. Furthermore, a channel can be programmed for enhanced measurement features to address requirements for tighter tolerance or higher speed.
For maximizing measurement speed, make measurements as short as 0. In addition, two modules have current measurement channels. Also select a control module and leithley RF modules with 2 GHz and 3. One option eases the identification of channels by allowing the creation of a name for each channel.
The DAQ has the built-in intelligence to execute a test script, make decisions, and control other instruments. Channels can be configured for any DMM measurement. Data can keitlhey stored to an external USB memory stick to prevent data loss in the event of interruption of line power.
TSP technology also offers mainframe-less channel expansion. Also save test time by reducing communication with the test controller. 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.
The D-sub connectors minimize downtime when changing plug-in switch modules during system maintenance or during the setup of a new test system. The system keithlsy organized in a master-subordinate configuration, essentially allowing the connected instruments to act as one.
There are additional optional parameters to adjust the measurements and the switching to meet a specific application. Measure up to 80 devices with two switch modules. This can significantly change the way information is displayed or even automated while running a test. In addition to an indication of measurements in an overflow condition, limit settings can be programmed for any channel. For maximum accuracy, measurements can be filtered and integrated over a range of time intervals.
The Keithley DAQ can be operated from the front panel while a test is in progress. The Status screen will display an out-of-limit indication when any channel’s measurement is outside keithly channel’s limit settings. Data can be viewed in a table or displayed on a plot without interrupting an automated scan sequence.
Next, assign a measurementfunction to a channel or a group of channels. Low resistance readings can be improved with a thermal offset compensation measurement technique.
That is the minimum set of parameters needed to run a test. Many of the plug-in switch modules have multi-pin D-sub connectors to ensure secure, minimal maintenance connections in automated test environments. If main power is lost, the Keithley DAQ will re-start the scan when keitbley power is restored. First, select the channels that will be used. Even switch signals from wireless devices with RF modules keithely a maximum switching frequency of 3.
Need to perform a quick check to ensure there are no problems with the measurements that the DAQ is taking? Two-year accuracy specifications are included, so you can be assured your critical measurements keithldy accurate and fully traceable. Test scripts can contain any sequence of routines that are executable by conventional programming languages including decision-making algorithmsso the instrument can manage every keithlry of the test without the need to communicate with a PC for decision making.
Using the TSP language keothley create a script, the user keityley display messages kfithley an operator in an automated or a semi-automated test system. 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. Thus, for most applications, the calibration cycle for the DAQ can be two years. In fact, the DAQ can execute an automated sequence entirely without a PC thus saving test time and reducing the capital cost of the system.
The touchscreen, graphic display shows the channel setup and the measurement programmed for each channel. These examples highlight the unique ability of the Keithley DAQ to run specialized applications that customize the user interface. You can control up to eight instruments at the same time and retrieve millions of readings from each instrument. Do all this from two menus and see – on one screen – how each channel is configured.
The DAQ also has an option to automatically restart scanning after a power interruption. Unplanned system downtime results keeithley loss of productivity and delayed product shipments or loss of valuable development time during product audit testing, accelerated life testing, and environmental testing.
Then define both the time interval between measurements and scans if multiple scans are required.
Providing the finest test equipment solutions since 1992
The dual functionality enables maximized utilization of your instrument. Connection is provided with simple low cost Category 5 Ethernet cabling. 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.
