PT5 Failure Description
You can determine failure results ($>0) by the individual bit settings:
BIT # PT5 Failure Description
0 Beam 1 Failure - A high value (normally 255) was <254, or a low value
(normally 0) was >20.
1 Beam 2 Failure - See Bit 0
2 Beam 3 Failure - See Bit 0.
3 Beam 4 Failure - See Bit 0.
4 Correlator Timeout - The CPU never received a "processing done" signal
from the Correlator.
PT6 – Receive Bandwidth
Purpose: This test measure the receive bandwidth of the system.
Format: PT6
Description: This test measure the receive bandwidth of the system. The
bandwidth varies with system frequency and the WB com-
mand setting. Beam fails if <75% or >125% of nominal value.
Example:
