My question is, with special probe (PR-60) connect in the oscilloscope (x100) attenuation, Can I measure directly AC power without isolation transformer? You have another problem. Most analog oscilloscopes can't do extensive trace math. To measure power, you must sample a voltage with one cha...
even if it's fast enough that it can't be perceived. This happens with both computer monitors (and other monitors on electronic devices) and LED light sources, especially those for mains voltage that can be dimmed on the primary side. Flicker free (non PWM) displays are fine...
Actually the R&D engineer uses an oscilloscope with CH1 attached to a simple AC current probe clamped around one cable (the positive one) The probe is from Chauvin Arnoux Mini-09 used mostly in 50Hz mains monitoring environment: Bandwidth is 48-500Hz. ...
Quote The short BNC - Coax cable should be OK, if longer termination at one end is a good idea. But careful with 50 Ohms termination at the scope and a higher DC voltage. With a supply with a floating output, there should be no need for a differential probe - with a grounded supply...
