a) In the home screen select:
● "Frequency" and "Level" in the status bar
● "Frequency" in the "Frequency" tile
● "Level" in the "Level" tile
● "Phase" in the "Frequency" tile
b) On the front panel:
● Press the [Freq] key
● Press the [Level] key
2. Enter the values as required.
The R&S SMA100B indicates the frequency and level settings in the status bar of the
home screen, and shows active functions and parameters of the RF signal in the "Fre-
quency" and "Level" tiles.
See "RF frequency and level display with a downstream instrument" on page 66.
RF frequency and level display with a downstream instrument
If your test setup includes a downstream instrument, you can enter the parameter of
the downstream instrument in the frequency or level settings dialog of the
R&S SMA100B. Examples of downstream instruments are mixers, frequency multipli-
ers, amplifiers or attenuators and of their corresponding major parameters offset, multi-
plier, amplitude. The R&S SMA100B generates the signal without the downstream
parameters, but considers all additional parameters concerning the frequency and
level.
Example parameters that affect the frequency and level:
●
Frequency offset
●
Multiplication factor
●
User correction
Any of these cases are indicated by a dedicated icon, displayed in the "Frequency" or
"Level" tile, depending on the affected parameter.
Figure 4-1 illustrates the calculation of the "Frequency" and "Level" values, displayed
in the status bar.
