|
Years in Production
|
Real
|
The numbers of years that the tube has been in production.

|
Power
|
Real
|
The value entered is based on the part type.
• For any Twystron type, the rated power of the tube in watts (W) for a non-Pulsed type or the peak rated power in megawatts (MW) for a Pulsed type.
• For any Magnetron type, the rated peak power of the tube in megawatts (MW).
• For any CW Klystron type, the average output power of the tube.
• For any Pulsed Klystron type, the peak output power of the tube in megawatts (MW).
|
|
Frequency
|
Real
|
The value entered is based on the part type.
• For any Twystron or Magnetron type and any Pulsed Klystron type, the operating frequency of the tube in gigahertz (GHz).
• For any CW Klystron type, the operating frequency of the tube. in megahertz (MHz).
