:CALCulate:AFANalyser:ALL:LIMit:LOWer[:DATA]
Description
Sets the upper limits for the six main audio frequency measurements with one com-
mand. The order of the floating point real numbers defines their meaning:
real1 represents the upper limit of the peak-to-peak AC voltage measurement; the
physical dimension of the number stated is V(pp).
real2 represents the upper limit of the RMS-valued AC voltage measurement; the
physical dimension of the number stated is V(rms).
real3 represents the upper limit of the RMS-valued measurement of an AC voltage
ripple on a DC voltage; the physical dimension of the number stated is V(rms).
real4 represents the upper limit of the audio frequency measurement; the physical
dimension of the number stated is Hertz.
real5 represents the upper limit of the distortion measurement, carried out on the
third harmonic of a sine wave. The physical dimension of the number stated is per-
centage.
real6 represents the upper limit of the SINAD signal-to-noise ratio measurement;
the physical dimension of the number stated is dB.
Query
The query form of this command is not supported.
Example
:CALC:AFAN:ALL:LIM:UPP 3,3,1,4000,5,100
Sets the upper limits for the audio measurements: 3 V for the peak-to-peak AC volt-
age, 3 V for the rms-valued AC voltage, 1 V for the rms-valued ripple voltage, 4 kHz
for the audio frequency, 5% for THD, and 100 dB for SINAD.

possible is 0.0001, the default value is 1.0.
real3: The minimum value is -40.0, the maximum is 40.0. The minimum resolu-
tion possible is 0.0001, the default value is -5.0.
real4: The minimum value is 0.0, the maximum is 20,000.0. The minimum res-
olution possible is 1.0, the default value is 1,000.0.
real5: The minimum value is 0.0, the maximum is 100.0. The minimum resolu-
tion possible is 0.1, the default value is 0.0.
real6: The minimum value is 0.0, the maximum is 100.0. The minimum resolu-
tion possible is 0.1, the default value is 0.0.
Description
Sets the lower limits for the six main audio frequency measurements with one com-
mand. The order of the floating point real numbers defines their meaning:

physical dimension of the number stated is V(pp).
real2 represents the lower limit of the RMS-valued AC voltage measurement; the
physical dimension of the number stated is V(rms).
real3 represents the lower limit of the RMS-valued measurement of an AC voltage
ripple on a DC voltage; the physical dimension of the number stated is V(rms).
real4 represents the lower limit of the audio frequency measurement; the physical
dimension of the number stated is Hertz.
real5 represents the lower limit of the distortion measurement, carried out on the
third harmonic of a sine wave. The physical dimension of the number stated is per-
centage.
real6 represents the lower limit of the SINAD signal-to-noise ratio measurement;
the physical dimension of the number stated is dB.
