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:
real1
represents the lower limit of the peak-to-peak AC voltage measurement; the
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.
Query
The query form of this command is not supported.
Example
:CALC:AFAN:ALL:LIM:LOW 1,1,0,400,0,25
Sets the lower limits for the audio measurements.
Syntax
:CALCulate:AFANalyser
:ACVoltage:PPEAk:LIMit[:FAIL]?
Parameters
There are no parameters.
Description
There is solely a query form of this command available.
Query
This command delivers one boolean number, indicating whether the user-definable
limits of the peak-to-peak measurement of the AC voltage applied to the audio ana-
lyzer were violated by a measurement result value or not.
A
0
means that the measurement result value is within the limits set, while a
1
indi-
cates that at least one measurement result value did violate at least one of the limits.
The limits can be set using the commands described below.
