R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Instrument Functions
Analyzer Mode
DECIM SEP In the case of floating-point numbers, use the DECIM SEP softkey to select between
'.' (decimal point) and ',' (comma) as the decimal delimiter for the ASCII FILE
EXPORT function.
By selecting the decimal delimiter, various language versions of evaluation programs
(e.g. MS Excel) are supported.
PAGE UP /
PAGE DOWN
NOISE CORR
(ON OFF)
Remote command: FORM:DEXP:DSEP POIN
Using PAGE UP and PAGE DOWN, you can scroll forward and backward through
the peak list pages.
They are active only as long as a peak list is displayed.
The noise correction for spurious emission measurements is available only if the
spurious emission measurement is active.
Note that noise correction for spurious emission measurements is available only if
the detector in the sweep list is the same in every sweep range.
For details on the effetcs of noise correction see NOISE CORR (ON OFF).
4.5.13.11 Spectrum Emission Mask Measurement
The Spectrum Emission Mask (SEM) measurement defines a measurement that
monitors compliance with a spectral mask. The SEM measurement of the base unit
allows a flexible definition of all parameters in the SEM measurement. The analyzer
performs measurements in predefined frequency ranges with settings that can be
specified individually for each of these ranges.
For this purpose, the SWEEP LIST settings or the current instrument settings are
used. Up to 20 subranges can be defined (they need not directly follow one another)
across which the analyzer sweeps in subsequent order. However, the measurement
ranges must not overlap. The measurement parameters can be selected independently
from each other in every subrange (SWEEP LIST menu, EDIT SWEEP LIST).
In the Spectrum Emission Mask, as in the Spurious Emissions measurement, a
range defines a segment, for which you can define the following parameters separately:
start and stop frequency, RBW, VBW, sweep time, reference level, attenuator
settings, and limit values. Via the sweep list, you define the ranges and their settings
(for details on settings refer to the SWEEP LIST softkey).
The following rules apply to ranges:
• The minimum span of a range is 10 Hz.
• The individual ranges must not overlap (but need not directly follow one another).
• The maximum number of ranges is 20.
• A minimum of three ranges is mandatory.
• The reference range cannot be deleted (it is marked in with "Ref").
The frequency range where measurements are actually performed is set by the start
and stop frequency parameters of the analyzer; these parameters are independent
of the sweep ranges. It is thus possible to define sweep ranges for a measurement
task that can be stored and reloaded and to quickly and easily set the frequency
range to be actually measured by means of two parameters; complex editing in the
sweep table is not necessary.
