Easily Generate Structure Functions and Determine Thermal Resistance
Capabilities previously only available in an expensive, single-purpose instrument are now available when the Vektrex SpikeSafe SMU is ordered with the optional BIAS function. Now included with the SMU’s BIAS function is support for logarithmic sampling. Logarithmic sampling makes it easy to measure component, circuit board, or luminaire thermal resistance using the JESD51-14 method. When log sampling mode is selected, the SMU’s digitizer continuously captures and boxcar averages samples. Vektrex’s Control Panel software application then time-tags and saves the data in a compact log data file. This log file may then be imported into free software tools such as JEDEC’s free thermal analysis tool, to create thermal transient plots, structure functions and to calculate thermal resistance.
