:CALCulate:AFSPectrum:TEMPlate:LIMit:LOWer
:CALCulate:AFSPectrum:VALue?
:CALCulate:AFSPectrum:MAXPeak
Syntax
:CALCulate:AFSPectrum:TEMPlate:LIMit:LOWer
<real1>,<real2>,<real3>,<real4>,
<real5>,<real6>,<real7>,<real8>, <real9>,<real10>
Parameters
The realx values are floating point real numbers.
The minimum value is -120, the maximum value is +10. The resolution for all values
is 0.1. The values are the lower limits for the audio template in dB, relative to the
reference level.
Description
Sets the lower limits for the user-definable audio spectrum template. These upper
limits refer to the frequencies defined in the FREQuency command above.
Query
The query form of this command is not available.
Example
:CALC:AFSP:TEMP:LIM:LOW -25, -25, -25, -25, -25, -25,
-25, -25, -25, -25
This command sets all lower limits to -25 dB at the frequencies defined with the
:CALC:AFSP:TEMP:LIM:FREQ command.
Syntax
:CALCulate:AFSPectrum:VALue? <real1>
Parameters
real1 is a floating point real number. It provides the position on the frequency axis
for which the audio spectrum value is being requested.
Query
Provides the measurement value (audio spectrum level) for the given frequency value.
If there is no measurement value at exactly this frequency, the value is interpolated.
Example
:MEAS:BLOC:AFSP:AVG
:CALC:AFSP:VAL? 1200
Delivers the audio spectrum value at the frequency of 1.2 kHz.
Syntax
:CALCulate:PSUPply:MAVerage?
Parameters
There are no parameters.
Description
There is solely a query form of this command available.
Query
The query form of this command delivers back the frequency (in Hz) and the maxi-
mum audio spectrum level of the measured audio spectrum curve. The string returned
will contain two floating point real numbers. The physical dimension of the measure-
ment result values returned is for the first value Hz and for the second value dB.
Note: Please note that you need to have a audio measurement taken before this
command will return any meaningful result. We recommend to use the
:MEAS:BLOC:AFSP:AVG command to do so.
Example
:MEAS:BLOC:AFSP:AVG 10
:CALC:AFSP:MAXP?
This command will read at the audio spectrum measurement maximum the frequency
and the measurement result value. The values returned in this example is:
"1230.0,-5.2"
