DC operation - cathode at one end only. AC, DC operation - cathodes at both end. Pulse operation - cathode at one end specially designed for pulse operation. If the anode
current during the “on” tie of a square wavepulse (>100µ duration) is nominally the same as the rated DC anode current, the tube drop during this period will be approximately
the same as the rated DC tube drop.
Excess noise ratio of tube only.
