1/
Two resistors, one in series with each ignitor, are encapsulated as integral parts of the tube. They are selected to provide a current
of 150 µA dc nominal when the specified voltage, Ebb = -860 V dc, is applied to the ignitor terminals (No. 1 and No. 2) of the
tube.
2/
A suitable gasket should be bolted between each flange of the tube and its mating flange (see figure 6).
3/
The minimum interchannel isolation (crosstalk) requirements shall be met when the tube is mounted between waveguide adapters
with standard 0.040 commonwall flanges. Tube shall be in the deionized state for this test.
4/
The shutters provide a convenient method of opening or shorting a waveguide line at low-power levels (incident peak power less
than 1 kw). They are not intended for applications involving the switching of high power, and should remain open or closed
whenever high power is incident on the tube.
