I/Q Level Vp EMF
Sets the output voltage for both signal components. Small differences at the inputs can
be taken into account via impairment settings (see chapter 5.7.1.1, "Impairment Settings
Menu", on page 289).
Single ended Output:
●
Value range: 20 mV ... 2 V EMF.
●
The maximum overall output voltage ("Level
EMF
" + |"Bias
EMF
"|) is 3.7 V.
Differential Output:
●
Value range: 40 mV ... 4 V EMF.
●
The maximum overall output voltage ("0.5" * "Level
EMF
" + |"Bias
EMF
"| + "0.5" * "Off-
set") is 3.7 V.
SCPI command:
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:POWer:PEP on page 730
Resulting I/Q Level Vp EMF
Displays the resulting output off-load voltage of both signal components at the rear panel.
SCPI command:
[:SOURce<hw>]:IQ:OUTPut[:ANALog]:POWer:PEP:RESult on page 731
Couple IQ Bias
(Variable output mode only)
Activates/deactivates coupling of bias setting of the I-signal and Q-signal component. For
activated coupling, the setting can be made for the I-signal component, it automatically
applies to the Q-signal component as well. The fields for setting the Q-signal component
are shaded.
SCPI command:
[:SOURce<hw>]:IQ:OUTPut:BIAS:COUPling[:STATe] on page 728
Bias (EMF)
Sets the bias. A DC voltage is superimposed upon the I or Q signal. The maximum overall
voltage ("Level
EMF
" + "Bias
EMF
" + "Offset
EMF
") is 3.7 volts.
This way, the operating point of a DUT can be set.
SCPI command:
[:SOURce<hw>]:IQ:OUTPut:BIAS:I on page 729
[:SOURce<hw>]:IQ:OUTPut:BIAS:Q on page 729
Offset (EMF)
(available only for output type "Differential" only)
Sets an offset between the inverting and the non-inverting output.
The value range is dynamically adjusted in order to respect the following constrains:
The maximum overall voltage ("Level
EMF
" + "Bias
EMF
" + "Offset") is 3.7 V.
The set value is set half in the positive and half in the negative direction:
●
A positive offset is set with half of the value in positive direction at the non-inverting
outputs, in negative direction at the inverting outputs, respectively.
