Figure 1: Cathode Voltage (Start - Preheat - Running)
This figure depicts the increase in cathode resistance
during the preheat phase prior to ignition.
Figure 2: Cathode Current (Start - Preheat - Running)
(500mA/div) This figure depicts the almost constant
current in the cathodes which decreases after ignition.
Figure 3: Lamp Voltage (Start - Preheat - Running)
This figure depicts the magnitude of the lamp voltage
during preheat, at ignition and during running.
Figure 4: Lamp Current (Start - Preheat - Running)
(200mA/div) This figure depicts the lamp
current during preheat and after ignition.
