(1)
DC operation — cathode at one end only.
AC,DC operation — cathodes at both ends.
Pulse operation — cathode at one end specially designed for pulse operation. If the anode current during the “on” time of a square wavepulse (>100
μ
s 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.
(2)
Excess noise ratio of tube only.
