These two words convey the measured I and Q DC osets from the last noise sample. The
output format is either signed 16-bit values in which ±32767 represent ±1.0 (legacy format),
or packed time series values using the High-SNR encoding format. Bit-9 of GPARM
Word-59 shows which format to use.

Bit 0
No Trigger during noise measurement
Bit 1
Trigger too fast during noise measurement, that is, some of the noise sample bins
were positioned past the trigger range
Bit 2
No trigger during PROC command
Bit 3
PRT varied by more than 10 μsec within portions of a processing interval that should
have been at a fixed rate.
Bit 4
Error in polarization control and/or polarization status readback
Bit 5
FIFO overflow during last PROC command
Bit 6
Command received while waiting for output FIFO space The command was processed,
but some output data has been lost (zeroed)
Bit 7
Error detected during last SNOISE command
Bit 9
Error in last Load Range Mask (LRMSK) command. This generally means that too many
range bins were selected.
Bit 10
Error in LSIMUL command protocol
Bit 11
Measured phase sequence is incorrect
