First video on "Using the 43101 Tester for Decibel Measurements". In this video, I check the tester itself for suitability for measurements in the audio range.
Passport data is one thing. Practical confirmation of suitability is another matter. At the same time, it will be useful for novice radio amateurs to understand how the verification takes place and, I'm not afraid of this word, the verification of the device. The video also shows an example of plotting a percentage and decibel deviation graph in the Microsoft Excel office application.
In the same way, you can build the amplitude-frequency characteristics in cases where there are no automatic building tools at hand or, for example, you do not want to bother connecting a computer. And it is not always possible to use software for measuring the frequency response - just like in this video, it is impossible to automate the process, since you have to manually set the readings of the tested tester at each point.
Test equipment and devices for testing 43101:
Low-frequency signal generator G3-112 in sinusoidal mode;
Digital voltmeter V7-38 with 20,000 counts;
Analog millivoltmeter V3-56 with a frequency range up to 15 MHz.
A time machine for lovers of Soviet measurement.
Made in USSR!
