Analyzer ltube-tester module - curve plotter. Equipped with a microprocessor, just need to connect a small transformer of 24 to 28 volts (0.15 A) and a transformer for the high voltage and the heating of the tube to get a fully functional tube tester capable of testing all types of tubes, editing the families of curves and automatically obtain the values of the slope (Gm), internal resistance (Rp) and gain (µ) characteristics.
The device works with a computer on a usb port and all the measurement parameters are programmable.
The analyzer can work in triode or "other" mode (multigrid tubes: tetrodes, pentodes, etc.). In multigrid mode an additional screen voltage must be supplied to grid 2 (screen) of the tube.
The card is supplied wired, set & ready to use, comes with its pc software on CD (windows all versions from win95 to Win 10 included) and its start - up and user manual.
