Measuring of impulse voltage

Post by santander »

Hello,

I am using Picoscope to investigate rise time and half time of voltage pulses in the microsecond range.

I played around with it for the first time yesterday and I love it! Thank you for a great product.

I would like to set up a measurement that could display the time from the pulse reaches 50 % of the peak level until it decays to the 50 % level again.

I can measure this manually with rulers, it would be great to have an automatic measurement for this

Is this something that I can set up easily?

Hi santander,

What you're describing is "High Pulse Width", which you can find if you go to 'Measurements->Add Measurement', and then select 'High Pulse Width', in the drop down list for 'select the type of measurement'. However, the "standard" automatic measurements can only display one value. So, if your captured data includes only one high half of a pulse, then the automatic measurement "High Pulse Width" will give you exactly what you need. If you have more than one high-half of the pulse captured, then the automatic measurement "High Pulse Width" will give you the average of that value for the displayed pulses. If you want each individual "High Pulse Width" measurements for multiple captured pulses, then you can use our "Deep Measure" feature to give you a Table of various measurement values for each pulse, including "High Pulse Width".
