Description of command
These commands are always queries. They return the audio level in the subranges defined by means of the
CONFigure:SUBarrays:MULTitone:AF1Channel command. In the default setting of the configuration
command the READ:SUBarrays..., FETCh:SUBarrays..., and SAMPle:SUBarrays... command
group is equivalent to the READ:ARRay..., FETCh:ARRay..., and SAMPle:ARRay... command group
described above.
The CONFigure:SUBarrays:MULTitone:AF1Channel command defines a maximum of 32 subranges. If
one of the statistical modes (ARIThmetical, MINimum, MAXimum) or IVAL is set, only one value is returned
by subrange.

Returned result
Value range Def. value Def. unit FW vers.
Limit matching at tone <nr> NMAU | NMAL | INV | OK INV – V3.0
Description of command
This command is always a query. It indicates whether and in which way the error limits at tone <nr> (<nr> = 1 to
20) have been exceeded.
The following messages may be returned for test tone <nr>:
NMAU Underflow of tolerance value
not matching, underflow
NMAL Tolerance value exceeded
not matching, overflow
INV Measurement invalid invalid
OK all tolerances matched
CALCulate[:SCALar]:MULTitone:AF1Channel:MATChing:LIMit? Limit Matching, Overall

Limit matching at tone 1,
...,
Limit matching at tone 20
For tones 1 to 20:
NMAU | NMAL | INV | OK
INV – V3.0
Description of command
This command is always a query. It indicates whether and in which way the error limits at all test tones 1 to 20
have been exceeded. The output string contains 20 values separated by commas.
