[SENSe<Sensor>:]TRACe:AVERage[:STATe]
<state>
Enables or disables the averaging filter in trace mode.
Parameters:
<state>
*RST:
ON
[SENSe<Sensor>:]TRACe:DATA?
Returns the measured trace data in a well-defined format.
Unlike
FETCh<Sensor>[:SCALar][:POWer][:AVG]?
, this command takes the set-
tings of
into account, as explained below.
Command response
Besides the average power, the power sensor can measure additional measurands like
minimum, maximum or random. These additional measurands are denoted as auxiliary
measurands and are selected by
A trace measurement can deliver up to 3
measurands. Therefore, the resulting block of
data returned can contain up to 3
blocks of user data.
Basically, the
response represents a "definite length
arbitrary block response data" as defined in IEEE488.2. This object consists of a
header and content.
In principle, the response has the format as shown in
#
n
LLLL
user data content
<LF>

#
Starting character
n
Single digit that defines how many of the following digits are interpreted as the size of
the content.
LLLLL
Number consisting of as many digits as specified by "n". This number gives the size
of the content.
User data content
. As many bytes as specified by "LLLLL".
<LF>
Single linefeed character
Examples
The arbitrary block response data for a user data that contains 45182 bytes is:
#545182xxxxxx.......xxxxxx <LF>
