Description of command
This command is always a query. It indicates whether and in which way the tolerances for the scalar measured
values (see command above) have been exceeded.
The following messages may be output for the value AvgBurstPowerCurr :
OK Tolerance value matched OK.
NMAU Underflow of tolerance value not matching, underflow
NMAL Tolerance value exceeded not matching, overflow
INV Measured value invalid invalid
The following messages may be output for the value BurstMatching :
INV invalid
MATC matching
NMAT not matching
OUT out of range
NTR no trigger
NRAM not ramping (burst not found)
OFLW overflow
UFLW underflow
NTSC no training sequence code
OFF off

Description of command
These commands are always queries. They output the different power values of the bursts in a fixed ¼-bit
pattern. The number of measured values is 428, corresponding to a time range of –10 bit to 96 ¾ bit.
