Figure 8-13: User data content format (byte)
1
Result type
Always 3
bytes, one for
AVG
, one for
MIN
and one for
MAX
or
RND
2
Data type
Designator for the contained data type with the size of 1
byte. Currently, the only possible designa-
tor is "f" for 4-byte IEEE754 float data type, little endian.
3
Single digit that defines how many of the following digits are interpreted as the number of con-
tained float values.
4
User data length
Number consisting of as many digits as specified by (3). This number gives the number of con-
tained float values contained in the user data.
5
User data
Measurement result values in the format that is described by the data type. Currently IEEE754 float
only.
measurands have been activated before execut-
ing the measurement, the user data content is finished here. In case that auxiliary
measurands have been selected, the above section is repeated for every auxiliary
measurand. The user data content looks like:
AVGf3100...(400byte AVG values)...MINf3100...(400byte min.
values)...MAXf3100...(400byte max. values)...
Where each of
...(400byte AVG values)...
...(400byte min. values)...
...(400byte max. values)...
Stands for 400
bytes as the equivalent of 100
float values.
The user data content is embedded in the arbitrary block response data response.
Example:
TRAC:DATA?
Usage:
Query only
SENSe<Sensor>:TRACe:FFT:DATA?
Returns a power spectrum of the measured trace data, showing the course of power
over a frequency range.
