Signal Output
Comprises the level settings of the output signal. The signal level is expressed as a
peak or RMS level value.
If R&S SGT is connected to the DIG I/Q interface of the R&S SMW, the level parame-
ters are set automatically.
Note: The "Level" display always refers to both signal components, i.e. SQR(I
2
+Q
2
).
"Set Level Via"
Selects whether the signal level is expressed as a peak or as RMS
level value.
Remote command:
[:SOURce]:IQ:OUTPut:DIGital:BBMM<ch>:POWer:VIA on page 1058
[:SOURce]:IQ:OUTPut:DIGital:FADer<ch>:POWer:VIA on page 1058
"Peak Level"
Enters the peak level of the output signal relative to full scale of 0.5 V
(in terms of dB full scale).
Remote command:
[:SOURce]:IQ:OUTPut:DIGital:BBMM<ch>:POWer:PEP on page 1058
[:SOURce]:IQ:OUTPut:DIGital:FADer<ch>:POWer:PEP on page 1058
"Level"
Enters the RMS level of the output signal.
Remote command:
[:SOURce]:IQ:OUTPut:DIGital:BBMM<ch>:POWer:LEVel on page 1059
[:SOURce]:IQ:OUTPut:DIGital:FADer<ch>:POWer:LEVel on page 1059
User Variation
If the rotary knob is used to adjust the level values, the step width can be defined. The
configured step width applies with activated variation.
If R&S SGT is connected to the DIG I/Q interface of the R&S SMW, "User Variation" is
disabled.
"Variation Active"
Enables the user-defined step width.
Remote command:
[:SOURce]:IQ:OUTPut:DIGital:BBMM<ch>:POWer:STEP:MODE on page 1059
[:SOURce]:IQ:OUTPut:DIGital:FADer<ch>:POWer:STEP:MODE on page 1059
"Variation Step"
Sets the user defined step width.
Remote command:
[:SOURce]:IQ:OUTPut:DIGital:BBMM<ch>:POWer:STEP[:INCRement]
on page 1059
[:SOURce]:IQ:OUTPut:DIGital:FADer<ch>:POWer:STEP[:INCRement]

Signal Monitoring
The R&S SMW monitors constantly the output signal and indicates overflow, if the digi-
tal signal is clipped. Overload can occur if the level of the output signal, or the noise
level (AWGN) are too high.
