Description of command
These commands are always queries. They start a measurement and return all scalar measurement results (see
chapter 5). These are:
Average power of current burst
Peak power of current burst
Burst out of tolerance
Average power of averaged trace
The calculation of results in an average or peak measurement is described in chapter 3 (cf. display modes ).The
following messages may be returned 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
This command is always a query. It indicates whether and in which way the permissible tolerances for the scalar
measured values (see command above) have been exceeded.
The following messages may be returned for the values A vgBurstPower and PeakBurstPower :
NMAU Tolerance value underflow not matching, underflow
NMAL Tolerance value exceeded not matching, overflow
INV Measurement invalid invalid
OK Tolerance value matched
The following messages may be returned for the value BurstMatching :
MATC matching
NMAT not matching
INV invalid
NTSC no training sequence code
