C Noise PEP / Noise PEP (Total Bandwidth) / C Interferer
PEP / Interferer PEP
Available only for "Mode > Additive Noise" and "Mode > CW Interferer".
Displays the peak envelope power (PEP) of the overall signal comprised of noise sig-
nal plus useful signal.
The output selected with the parameter
determines:
●
The name of this parameter
●
The units the overall power is measured in, dBm or dB (full scale)
Note:
The peak envelope power ("PEP") displayed in the "Status bar" corresponds to
the PEP value of the carrier.
Remote command:
[:SOURce<hw>]:AWGN:POWer:SUM:PEP?
7.3 I/Q Modulation and Impairment Settings
7.3.1 I/Q Modulation
The R&S
SGT offers I/Q modulation with:
●
External analog I/Q signals,
●
External digital signals,
●
Iternal digital signals.
Either the external digital signal or the externally or internally generated baseband sig-
nal is fed into the I/Q modulator ("I/Q Mod" function block).
The external signal is input via the I and Q connector and transferred directly to the I/Q
modulator ("I/Q Mod" function block). The external digital signal is configured in the
"BB In" function block (see
Chapter 7.9, "External Baseband Signal - Baseband Input"
The internally generated baseband signal is configured in the Baseband function block
(see
on page 75). Before the signal is fed into the I/Q modu-
lator, noise can be added and/or the signal can be impaired.
Impairments can also be set in the I/Q Mod menu to allow an externally applied analog
I/Q signal to be impaired. An internal baseband signal can thus be impaired both digital
(in the Impairment block in the Impairment menu) and analog in the I/Q modulator. If
impairments are set in both menus, they superimpose each other in the signal.
