Note: User standards created on an analyzer of the R&S FSP family are compatible to
the R&S FPL1000. User standards created on an R&S FPL1000, however, are not
necessarily compatible to the analyzers of the R&S FSP family and may not work
there.
The following parameter definitions are saved in a user-defined standard:
●
Number of adjacent channels
●
Channel bandwidth of transmission (Tx), adjacent (Adj) and alternate (Alt) chan-
nels
●
Channel spacings
●
Weighting filters
●
Resolution bandwidth
●
Video bandwidth
●
Detector
●
ACLR limits and their state
●
"Sweep Time" and "Sweep Time" coupling
●
Trace and power mode
Save the current measurement settings as a user-defined standard, load a stored mea-
surement configuration, or delete an existing configuration file.
For details see "How to Manage User-Defined Configurations" on page 272.

Number of channels: Tx , Adj
Up to 18 carrier channels and up to 12 adjacent channels can be defined.
Results are provided for the Tx channel and the number of defined adjacent channels
above and below the Tx channel. If more than one Tx channel is defined, the carrier
channel to which the relative adjacent-channel power values should be referenced
must be defined (see
" Reference Channel " on page 265).
Note: If several carriers (Tx channels) are activated for the measurement, the number
of sweep points is increased to ensure that adjacent-channel powers are measured
with adequate accuracy.
For more information on how the number of channels affects the measured powers,
see
Chapter 7.2.3.2, "Channel Power Results" , on page 256.
