R&S FSP Instrument Functions
Analyzer Mode
= MARKER The = MARKER softkey sets the step size coupling to MANUAL and the step size to
the value of the marker. This function is especially useful during measurements of
the signal harmonic content at the marker position because by entering the center
frequency each stroke of the
STEP key selects the center frequency of another har-
monic.
Remote command:
--
MANUAL The MANUAL softkey activates the window for entering a fixed step size.
Remote command:
FREQ:CENT:STEP 120MHz
Softkeys in time domain:
0.1 * RBW The 0.1 * RBW softkey sets the step size for the center frequency entry to 10% of
the resolution bandwidth.
AUTO 0.1 * RBW corresponds to the default setting.
Remote command:
FREQ:CENT:STEP:LINK RBW
FREQ:CENT:STEP:LINK:FACT 10PCT
0.5 * RBW The 0.5 * RBW softkey sets the step size for the center frequency entry to 50% of
the resolution bandwidth.
Remote command:
FREQ:CENT:STEP:LINK RBW
FREQ:CENT:STEP:LINK:FACT 50PCT
X * RBW The X * RBW softkey allows the factor defining the center frequency step size to be
entered as % of the resolution bandwidth.
Values between 1 and 100% in steps of 1% are allowed. The default setting is 10%.
Remote command:
FREQ:CENT:STEP:LINK RBW
FREQ:CENT:STEP:LINK:FACT 20PCT
= CENTER The = CENTER softkey sets the step size coupling to MANUAL and the step size to
the value of the center frequency. This function is especially useful during measure-
ments of the signal harmonic content because by entering the center frequency
each stroke of the
STEP key selects the center frequency of another harmonic.
Remote command:
--

the value of the marker. This function is especially useful during measurements of

monic.
