NOTES:
1/
This measurement shall be made with the tube mounted in test cavity according to Drawing 162-JAN.
2/
No tube shall require more than the stated maximum ignitor current to prevent relaxation oscillations
when tested in the standard circuit.
3/
This measurement shall be made in test cavity according to Drawing 162-JAN. With the cavity
calibrator in position, the cavity shall be tuned to resonance and the relative transmitted power
level noted. With the tube inserted, the cavity shall then be tuned to resonance and the transmitted
power noted. The dB loss in transmitted power due to the insertion of the tube shall not be more
than the specified amount.
