A trace measurement with the R&S
NRPM can therefore be configured to return
up to three measurands on each channel/antenna module. As a consequence,
the resulting data which is provided by a
[SENSe<Sensor>:]TRACe:DATA
query can contain between 1 and 9 blocks of measurement data. For example, 1
resulting measurement data block if only one antenna module is used and only
average power is to be measured on that channel. 9 resulting measurement data
blocks if three antenna modules are used and average, min & max power is to be
measured on each channel.
To obtain a single measurement data block, you must first extract the contents of
the "Definite Length Arbitrary Block" which is returned from the
SENSe:TRACe:DATA
query. The format is defined in IEEE488.2.
In principle the response has the format as shown in
#
n
LLLL
user data content
<LF>
Header
Figure 10-2: Response format
Header
#
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 deter-
mines the size of the content.
User data con-
tent
. As many bytes as specified by "LLLLL".
<LF>
Single linefeed character
Example:
The arbitrary block response data for a user data that contains 45182 bytes is:
#545182xxxxxx.......xxxxxx <LF>
The arbitrary block response data for a user data content
'THIS IS A TEST'
is:
#214THIS IS A TEST<LF>
Explanation:
'THIS IS A TEST'
has 14 bytes, and '14' has 2 digits, hence the
#214
.
