The Tj Measurement Tookit is an optional add-on to the SpikeSafe Pulsed Source Measure Unit. It simplifies and automates junction temperature measurement for LED or laser devices using JEDEC’s Electrical Test Method (ETM).
Make accurate junction temperature measurements of LEDs, Lasers or VCELs
- Measure devices in lab setting
- Measure devices in-situ for example temperature chambers
- Supports single devices
- Support arrays of devices (ensembles)
Kit requires optional BIAS source is purchased with the Vektrex SMU or SMU High Current.
