Trigger 9C Description

Sequence: All
Trigger 9C: Toggle 10/80 kHz WBR

During the innermost SOI intervals, except during the burn, the A8 mode is used as the background mode. In addition, WBR data is acquired continuously, toggling between the 10-KHz and 80KHz bands every minute. A snapshot is taken every 1/8 second, consisting of 1437 uncompressed data bytes. The reason this is done is to target a 100 kbps data rate. The reason the data is not compressed is because compressing the 80-KHz data results in interruptions in the WFR and WBR data acquisitions, since they can not both be done at the same time unless the data is left uncompressed.
