This is the standardized code for the S-band magnetron NT98A, one of the four frequency variants for this magnetron.
- 3030 to 3060MHz
- 8A at 9.5KV input pulses
- 8kW typical, 5 kW minimum output pulses at 1080 oersteds
In this family frequency selection took place on the test bench after the tube sealing off. All the tubes made were labeled as NT98 and the frequency suffix was added later with a different ink.
