TWP/KAZR/C1 - 16.56 GHz PLO failure
DataStreams:twpkazrauxC1.a0, twpkazrgeC1.a1, twpkazrhiC1.a1
Description:
The TWTA failed.  It was replaced and after some troubleshooting, we found that the 16.56 
GHz Phased Lock Oscillator (PLO) was bad. Instrument returned to service 20130712.
Suggestions: 
Do not use the data during this period.
