= 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
measurements of the signal harmonic content because
by entering the center frequency each stroke of the STEP
key selects the center frequency of another harmonic.
IEC/IEEE-bus command: --
= 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
harmonic.
IEC/IEEE-bus command: --
MANUAL
The MANUAL softkey activates the window for entering a
fixed step size.
IEC/IEEE-bus command: FREQ:CENT:STEP 120MHz
Softkeys in time domain:
AUTO
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.
IEC/IEEE-bus command: FREQ:CENT:STEP:LINK
RBW
FREQ:CENT:STEP:LINK:FACT 10PCT
AUTO
0.5 * RBW
The 0.5 * RBW softkey sets the step size for the center
frequency entry to 50% of the resolution bandwidth.
IEC/IEEE-bus command: FREQ:CENT:STEP:LINK
RBW
FREQ:CENT:STEP:LINK:FACT 50PCT
AUTO
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%.
