Clock Phase
Sets a phase shift of the active clock edge in 90° steps related to the data bits.
The phase shift is graphically displayed in main settings dialog.
Adjustable values: 0° | 90° | 180° | 270°
Example:
Fig. 7-36: User defined > Clock phase
Clock source = internal
clock phase = 90°
Note: SCPI notation varies
In the remote control you determine the clock phase value for the R&S signal analyzers
with
Pxx
. In contrast, just enter the value
xx
without
P
when using R&S EX-IQ-BOX or
an R&S signal generator.
xx
represents the value in degree.
Follow the command link below for description of the command and its syntax in detail.

Clock Skew
Sets a time shift of the active clock edge related to the data bits. This feature is used to
compensate an external clock skew which is caused by differences of the clock and data
line lengths.

Frequency
Sets / indicates the reference frequency.
The R&S EX-IQ-BOX supports different reference frequencies to be input at REF IN. This
value must be set on the frequency currently supplied.
