Solar Analytics RIPPED ME OFF!
Jacked up their fees 40% above what their website says, and they refuse to respond to me. So screw them, I'm looking for a new home circuit energy monitoring system.

Demonstrating the difference between Schottky diodes and PN junction silicon diodes, and how your multimeter can influence your measurement when troubleshooting.
Answering an interesting Twitter question.

00:00 - Twitter question
01:21 - Recreating the problem
03:08 - Why doesn't it read zero volts? Let's try a PN junction diode
04:21 - Schottky vs PN Junction diodes, they are NOT the same!
06:06 - What about a diode tester?
07:15 - Why doesn't the Schottky diode work like a diode?
08:39 - It's a multimeter measurement TRAP!
10:37 - A closer look at Schottky diodes
14:21 - Datasheet inspection, and advantages vs disadvantages of Schottky diodes
15:21 - Reverse leakage current, PN vs Schottky
17:16 - THREE orders of magnitude difference!
22:29 - Digital vs Analog multimeter, Analog WINS!

Walk time rant. The NBN Internet in the Norwest Business Park has been down for 6 days now since April 24th, and was supposed to be fixed today. But the latest update is now 8th May!
This impacts thousands of businesses in the business park, and Telstra mobile is on it's knees as a result as everyone scrambles for another solution. And my backup Optus 5G connection is also barely operational under the strain.
I'm uploading this from home because I only have 1Mbps upload speed at the lab.

The DP700 is Micsig's third suck of the sav on a high voltage differential probe. Not to be confused with the MDP700 which this replaces.

https://www.micsig.com/DPA/

00:00 - Comparison to the DP10007 and MDP700
03:58 - Unboxing of the DP700
05:52 - CMRR measurement hardware setup
09:52 - Sanity check gain and bandwidth check.
11:29 - Zero function
12:25 - Measuring the CMRR
16:30 - Trap for young players. RMS vs AC RMS, it's all in the sigma
17:44 - Another trap for young players, double sigma
19:07 - CMRR at 100MHz
22:41 - Real world test on a 100V GaN MOSFET
25:28 - Teardown
29:44 - PCB inspection
