Follow up on my road test of the Keithley Bench Digital Multimeter DMM6500.I proposed in my application to focus the review on instrument automation. In this post, the VSCode TSP Toolkit plugin. The plugin was released a few years...
Till now, I have used a self-adjusting wire stripper. It was quite good but sometimes stuttered during stripping. It didn't have an option to regulate the length of a stripped area of wire. I have decided to try something which allows me to regulate...
A while back I picked up a couple of FNIRSI instruments, a 2D15P scope and an LCR-P1 component tester. Good kit for the money, but the software is a letdown: mostly Windows-only, so on a Mac you're stuck dragging screenshot files off a USB drive by h...

A few years ago I looked for a replacement for my portable multimeter, the Appa iMeter 5, for which I was not fully satisfied. I have found a Sanwa PM300. I have been ...
Back in March, I was flabbergasted to be chosen as the grand prize winner for the Fun and Games competition
I mean, I was participating for the fun of it, thinking to myself "heck, if I reach second place, that'll be a good occasion to repla...
The channel isolation describes how much signal on one input channel unintentionally appears on another channel. In case when we are measuring some signal, e.g. on channel 1 and has channel 2 not connected to any signal, in an ideal scenario, there s...
Today arrived my power supply, that bought few days ago. It was a good occasion to buy almost not used device in half of current price. The device is in the condition as described by the previous owner. It still has a product seal. After disass...
Background
Today I have checked the input noise floor of the oscilloscope channel in Analog Discovery 3. By default, both oscilloscope channel inputs of the Analog Discovery 3 are not shielded. It is mentioned in this thread:

Introduction
I own a pretty old, portable PicoScope model (2000 series), which cost very little. Although I have larger desktop ‘scope options with screens, I still find that PicoScope gets used regularly. I’ve even written my own ‘...
I've desired a decent linear low-noise power supply for ages, and I think I've finally found one at a reasonable price.

I recently bought a new laptop to replace an ancient one, and this time decided to put more thought into how I organized things.
A problem for me is that I tend to install a lot of software tools and integrated development environments (...

I wrote a review (and created a video) for a Rohde & Schwarz FPC series spectrum analyzer eight years ago, and although I explored some of the demodulation capability back then, I never used it for a real-life scenario. Fas...

A Schmitt-trigger is a circuit that turns a non-perfect digital signal into a clean one. It has 2 main functions:
recreate a good fast ramp for signals that have lost their oomph (or never had clean fast edges).
