[SENSe:]ADEMod:SPECtrum:RESult? <result type>
This command reads the result data obtained by RF SPECtrum measurement depending on the type
indicated as a parameter. The data format of the output data block is defined by the FORMat
command.
Note: It is not possible to read out trace data when result type VIEW is selected.
Parameters: <result type>: WRITe The current measurement results will be obtained
AVERage The measurement results will be averaged over the
given # of measurements
MAXHold The maximum result values will be obtained over the
given # of measurements
MINHold The minimum result values will be obtained over the
given # of measurements
Notes: The result type indicated must be one of those configured by
[SENSe:]ADEMod:SPEC[:TYPE]. Otherwise a query error will be generated.
Return Values:
ASCII Format (FORMat ASCII):
In this case the command will yield a list of comma separated values (CSV) of the measured
values in floating point format. The output unit is dBm.
Binary Format (FORMat REAL,32):
In this case the command will yield binary data (Definite Length Block Data according to IEEE
488.2), each measurement value being formatted in 32 Bit IEEE 754 Floating-Point-Format.
The schematics of the result string will be as follows:
#41024<value1><value2>...<value n>
with
#4 number of digits (= 4 in the example) of the following number of data bytes
1024 number of following data bytes (= 1024 in the example)
<value x> 4-Byte-Floating Point Value
