Tektronix Keithley SourceMeter 2450 - Remote Communications and Device Connections

Section
6: Leakage current and insulation resistance Model 2450 SourceMeter® Instrument
User's Manual
6-2 2450-900-01 Rev. E / August 2019
Equipment required
• One 2450 SourceMeter
®
Instrument
• Two triaxial cables
• One capacitor for the leakage current application
• One coaxial cable or other device for the insulation resistance application
• One ethernet, GPIB, or USB cable for the TSP and SCPI remote command examples
Set up remote communications
You can run this application from the front panel or any of the supported communication interfaces for
the instrument (GPIB, USB, or ethernet).
The following figure shows the rear-panel connection locations for the remote communication
interfaces. For additional information about setting up remote communications, see
Remote
communications interfaces (on page 3-1).

Device connections
Depending on the device under test (DUT), the current measurement is typically very small, usually
<10 nA. For any device, measuring leakage current and insulation resistance involves measuring very
small values. To get more accurate readings, connect the DUT to the 2450 rear panel with low-noise
triaxial cables.
Connect the DUT between the FORCE HI and FORCE LO terminals of the 2450.
