Experiment: Thermionic Triode (230 V, 50/60 Hz), 8000658 [UE3070200-230], 电子管的实验
Thematic focus: ..
• Record the anode current/anode voltage characteristics for a thermionic triode at various constant grid voltages.
• Record the anode current/grid voltage characteristics for a thermionic triode at various constant anode voltages.

Experiment description: ..
At sufficiently high positive voltage between the cathode and anode (anode voltage), free electrons from the cathode can pass through the grid to reach the anode. The anode current generated in this way can be modulated by varying another voltage between the cathode and the grid. Depending on whether the grid is at positive or negative potential to the cathode, the anode current is either amplified or weakened. A thermionic triode can thus be used for amplifying AC voltages.
This experiment involves recording the set of characteristics for a thermionic triode. These incorporate the way the anode current IA depends on the anode voltage UA and on the grid voltage UG . There are two common ways of portraying these characteristics: Methode 1 monitors the anode current as a function of the anode voltage at various constant grid voltages and methode  2 monitors the anode current as a function of the grid voltage at various different constant anode voltages.
