*RST: REPeat
Example: TRAC:AVER:TCON REP
[SENSe<Sensor>:]TRACe:AVERage[:STATe] <state>
Switches the averaging filter on and off for the Trace mode.
Parameters:
<state> *RST: ON
[SENSe<Sensor>:]TRACe:DATA?
Returns the measured trace data in a well-defined format.
Unlike the
FETCh?
command,
[SENSe<Sensor>:]TRACe:DATA
takes the settings of
[SENSe<Sensor>:]AUXiliary
into account, as explained below.
Command response
To describe the format of the command response, it is important to know some addi-
tional information.
Besides the average power, the sensor can measure additional measurands like mini-
mum, maximum or random. These additional measurands are denoted as auxiliary
measurands and can be selected through the
[SENSe<Sensor>:]AUXiliary
com-
mand.
A trace measurement can be configured to deliver up to three measurands. Therefore,
the resulting block of data which is provided by a
[SENSe<Sensor>:]TRACe:DATA
query can contain 1 to 3 blocks of user data.
Basically, the
[SENSe<Sensor>:]AUXiliary
response represents a Definite Length
Arbitrary Block Response Data as defined in IEEE488.2. This object consists of a
header and some content.
In principle, the response has the format as shown in Figure 9-4 :

●
Header consisting of:
–
Character #
– Single digit ( 'n') which tells the number of following digits that is taken as the
size of the content.
– Number consisting of as many digits as 'n' specified ( 'LLLLL'). This number
gives the size of the content
