Oscilloscopes principally measure voltage and time. Measuring other electrical quantities, as a function of time, requires the use a transducer which converts the measured quantity into voltage. The Rescale math function in LeCroy Digital Oscilloscopes enables the users to convert this measurement into the proper units. LeCroy Application Brief LAB 427 shows how to use the rescale function to change from Volts into other units of measurement. I need to measure real and apparent power.
Oscilloscopes measure current and voltage and through the magic of mathematics calculate power.
This plethora of power terms often leads to confusion. This is a common question that arises when making measurements of timing jitter. I noticed the latest LeCroy scopes have buttons marked History and WavePilot. WavePilot and History provide fast access to the measurement and math tools available in LeCroy WavePro and Waverunner2 oscilloscpes. LeCroy Application Briefs LAB431 and 432 illustrated how they are used.
