Vacuum tube analyzer, lampemetre analyzer module with the software

Description

This module works with the computer ( serial port or USB port via an adapter) or the oscilloscope.
You also need an insulated transformer ( Can't use the mains as a source for the high voltage) and a 24VAC transformer, please check the connection by the 3rd picture,
High voltage Input 1 & Input 2 refer to the transformer high voltage secondary ( Plate voltage ).
The software can work under WinXP, Win7 32/64, Win10.
The system can be used in various ways :
1. Characterisation and measurement of vacuum tubes.
2. Publication of families of curves.
3. Tube matching.
4. Testing of parameters under different conditions of use.
5. Measurement beyond limits set by the manufacturer: the very weak dissipation of the vacuum tube under testing allows for the verification of characteristics beyond limited conditions.
