Operating Manual 1411.4060.32 ─ 04
The phase of the output signal can be changed in the "Phase Settings" section. The
"Phase Settings" menu is described in
chapter 5.3.3, "Phase Settings"
Frequency Settings
The frequency, offset and multiplier factor are set in the top section of the menu.
Frequency - RF Signal
Sets the RF frequency of the RF output connector. The frequency entered and displayed
here corresponds to the frequency at the RF output, i.e. any offset entry is not taken into
consideration.
Note:
The SCPI command
SOUR:FREQ
sets the frequency of the "FREQ" display, i.e.
the frequency containing offset.
SCPI command:
n.a.
Frequency Offset - RF Signal
Sets the frequency offset relative to the RF frequency. The frequency offset of a down-
stream instrument (e.g. a mixer) is entered.
The entry does not change the value of the RF frequency at the RF output. It only changes
the RF frequency displayed in the display header. The value of the RF frequency in the
header corresponds to the frequency at the output of the downstream instrument.
SCPI command:
Multiplier - RF Signal
Sets the multiplication factor for the RF frequency.
In the frequency field of the status bar, the instrument adjusts its frequency display
according to the set multiplication factor. This frequency value shows the frequency at
the output of the downstream multiplier. The entry does not change the RF frequency at
the RF output of the R&S SMC.
SCPI command:
User Variation
If the frequency is set using the rotary knob, the step width is defined in the "User Var-
iation" section.
Variation Active - RF Signal
Activates the user-defined step width used when varying the frequency value with the
rotary knob.
"ON"
The frequency value set with the rotary knob is varied using the user-
defined step width which is entered under "Variation Step".
"OFF"
The frequency value set with the rotary knob is varied in steps of one
unit at the cursor position (standard operating mode).
SCPI command:
RF Signal - RF Block
