Optimize IQ-Signals for RF Output
Activates/deactivates optimization of level accuracy and imbalance for RF Output.
Level accuracy and imbalance can be either optimized for RF output (active) or for dif-
ferential outputs (not active).
SCPI command:
[:SOURce<hw>]:IQ:OUTPut:BIAS:OPTimization[:RF]:STATe on page 640
I/Q Output Type
Selects the type of output. The analog outputs can be operated in "Single Ended" mode
or "Differential" (non-inverted) mode. The menu changes depending on the selected out-
put mode
"Differential"
Differential output at I OUT and I OUT BAR or Q OUT and
Q OUT BAR.
"Single Ended"
Single-ended output at I OUT and Q OUT.
SCPI command:
[:SOURce<hw>]:IQ:OUTPut:TYPE on page 642
Output Mode
Selects the mode for setting the outputs - independent or together. The menu changes
depending on the selection here.
"Fixed"
The settings for the I/Q signal components are fixed and cannot be
changed.
●
"Level Vp (EMF)" (Single ended) = 1.0 V
●
"Level Vp (EMF)" (Differential) = 2.0 V
"Variable"
The settings for the I/Q signal components are not fixed and can be
modified.
"Var. Attenu-
ated"
Enables a precise digital attenuation of the signal. The level of the
baseband and the RF signal is attenuated by the value set with the
parameter Digital Attenuation.
SCPI command:
[:SOURce<hw>]:IQ:OUTPut:MODE on page 641
I/Q Level Vp EMF
Variable output mode only
