Query parameters:
<ResultType>
IMMediate | AVERage
IMMediate
The current measurement results are used to calculate the FM
offset
AVERage
The measurement results that were averaged over the given
number of measurements are used to calculate the FM offset
If no average measurement was active during the last measure-
ment sequence only the
[SENSe:]ADEMod<n>:FM:OFFSet?
IMMediate
command will return a correct result (data to calcu-
late the offset are taken from the last measured data set).
[SENSe:]ADEMod<n>:FM:OFFSet? AVERage
will cause a
query error in this case.
Example:
ADEM:SET 8MHz,32000,EXT,POS,-500,30
Sets up demodulator parameters to execute 30 measurements
ADEM:FM AVER,OFF,OFF
Selects FM results to perform averaging
INIT; WAI
Starts measurement and waits for sync
ADEM:FM:OFFS? IMM
Reads FM offset of last measurement of the sequence of 30
ADEM:FM:OFFS? AVER
Reads FM offset averaged over 30 measurements
Usage:
Query only
11.7.4 Formats for Returned Values: ASCII Format and Binary Format
When trace data is retrieved using the
TRAC:DATA
or
TRAC:IQ:DATA
command, the
data is returned in the format defined using the
. The possible for-
mats are described here.
●
ASCII Format (FORMat ASCII):
The data is stored as a list of comma-separated values (CSV) of the measured val-
ues in floating point format.
●
Binary Format (FORMat REAL,32):
The data is stored as 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 schema of the result string is 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>
4-byte floating point value
