I am using my company's new oscilloscope and I don't want to mess it up. I have searched all of the topics, but nothing tells me exactly what I want to know so I thought I would ask in case somebody had the same question.
The team designed a switch-mode power supply and an audio amplifier. I'm supposed to test both, but I am a little embarrassed that I don't know what will and what won't blow-up the DUT, the scope, or the probe. We have a normal 115VAC/60Hz outlets, powering the oscilloscope and the AC power supply. We also have an isolation transformer if I want to plug it directly into the wall. I am using a differential probe, but I only have one of them and need to look at 2 signals at the same time. I have lots of single ended probes.
- Can I use a single probe anywhere if the equipment is on an isolated outlet (we have isolated outlets on the front of our AC supply).
- If that doesn't work, can I put the DUT on the isolation transformer and then use the single ended probe anywhere?
- If the DUT is on the isolation transformer, can I put the alligator clip anywhere I want? if I want to measure the high-side fet of a half-bridge LLC circuit, can I tie the ground clip to the switching net and it just behaves like a differential probe?
- Is there any danger in using signal ended probes on the primary side of the high-frequency transformer in the LLC and the secondary side of the high-frequency transformer at the same time?
I appreciate any help you can help me to learn how to do this correctly!
