- How to estimate the measurement uncertainty of an Textronics 500 MHz oscilloscope ?
I have an Textronics oscilloscope with 500 MHz sampling rate and using an 50 ohm cable for the measurement.
I can’t find the measurement uncertainty in the manual or the calibration sheet.
In the calibration sheet it says an ‘uncertainty’ for the used channel in divisions, for example 1m up to 10m (the scale) and with highest value being 1. It states the nominal value, upper and lower value and the measurement value. It also state an uncertainty (value between 1-2m) but not in %. I don’t understand how to determine the measurement uncertainty from this data. Anyone understand this?
The manual is even more cryptic .. no words on measurement uncertainty.
