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
Figure 10-1: Response format
●
The header consists of:
– The character #.
– A single digit ( 'n') which defines the number of the following digits taken as
the size of the content.
– A number consisting of as many digits as 'n' specified ( 'LLLLL'). This num-
ber determines the size of the content.
●
The content ('user-data-content'), see also
bytes as 'LLLLL' specified.
●
A single linefeed character (symbolically shown as <LF>,
).
Example:
The "Arbitrary Block Response Data" for a user data that contains 45182 bytes
would be:
#545182xxxxxx.......xxxxxx <LF>
The "Arbitrary Block Response Data" for a "user-data-content"
'THIS IS A
TEST'
would be:
#214THIS IS A TEST<LF>
