Diode Valve Characteristics Apparatus Original

The Diode Valve Characteristics Apparatus is an essential laboratory training system used to study and plot the current-voltage (V-I) relationship of a thermionic vacuum tube diode.

This specific educational unit is supplied by IBEX Sciences, a prominent scientific laboratory equipment provider located in New Anarkali, Lahore.

Technical Specifications & Features

The apparatus is fully self-contained and engineered to give students practical insight into thermionic emission and vacuum electronics. It typically includes:

• Dual Power Supplies:
  • High Tension (H.T.): A variable, regulated DC power supply (0–300V DC at 30 mA) to provide adjustable anode (plate) voltage.
  • Low Tension (L.T.): An AC power supply (6.3V AC at 1A) dedicated to heating the diode filament (cathode).
• Measurement Meters: Two built-in analog moving-coil meters are mounted on the front panel to simultaneously measure the anode voltage (\(V_{p}\)) and the resulting plate current (\(I_{p}\)).
• Front Panel Diagram: A clearly printed schematic valve diagram is featured on the steel-enclosure panel. All underlying power supply terminals and tube electrodes are brought out to secure sockets/terminals for easy wiring.
