Main PLL Bandwidth
Selects the PLL (Phase Locked Loop) bandwidth of the main synthesizer.
"Normal"
Default main PLL bandwidth.
The instrument provides the maximum modulation bandwidth and
FM/PhiM deviation.
"Narrow"
Sets the narrow PLL bandwidth.
Remote command:
[:SOURce<hw>]:FREQuency:PLL:MODE on page 649
Offset
Sets the frequency offset.
This value represents the frequency shift of a downstream instrument, like for example
a mixer.
The "Frequency" value displayed in the status bar is the resulting frequency, as it is at
the output of the downstream instrument. The frequency at the R&S SMA100B RF out-
put is not changed.
See "RF frequency and level display with a downstream instrument" on page 66.
Remote command:
[:SOURce<hw>]:FREQuency:OFFSet on page 646
Multiplier
Sets the multiplication factor for the RF frequency.
This value represents the multiplication factor of a downstream instrument, as for
example a multiplier. You can also assign a negative multiplication factor, for example
-1.0 to support frequency converters working in the reverse frequency position.
The "Frequency" value displayed in the status bar is the resulting frequency, as it is at
the output of the downstream instrument. The frequency at the R&S SMA100B RF out-
put is not changed.
See "RF frequency and level display with a downstream instrument" on page 66.
Remote command:
[:SOURce<hw>]:FREQuency:MULTiplier on page 646
User Variation
Defines and activates a user-defined step width for varying the RF frequency or RF
level with the rotary knob.
If disabled, the step width varies in steps of one unit at the cursor position.
Variation Active ← User Variation
Activates the set user-defined step width.
Remote command:
[:SOURce<hw>]:FREQuency:STEP:MODE on page 648
[:SOURce<hw>]:POWer:STEP:MODE on page 688
Variation Step ← User Variation
Sets the user-defined step width.
