The actual output PRBS waveform is as follows. C1 of the oscilloscope captures the "+" end of
the differential signal, C3 captures the "-" end, F1 = C1-C3, that is, the equivalent differential
signal.
9.5 Arbitrary Waveform Setting
Arbitrary waveform provides two modes: AFG and AWG. On the parameter setting page where
the carrier is an arbitrary waveform, click the value area of the "Mode" parameter setting box to
select the required mode:
9.5.1 AFG Mode
In AFG mode, the signal generator outputs the specified arbitrary waveform in the way of
traditional Direct Digital Synthesis (DDS) generators. At this time, the basic waveform parameter
setting is the same as that of the sine wave. Refer to the section "Standard waveform setting".
For data source selection and editing of an arbitrary wave, refer to the section "Data source".
9.5.2 AWG Mode
In AWG mode, the signal generator employs SIGLENT’s TrueArb Technology (Figure 9.2) and
outputs the specified waveform sequence point-by-point with a user-specified sample rate.
TrueArb overcomes the intrinsic defects of traditional DDS technology that may increase jitter
and distortion when generating arbitrary waves, while retaining its advantages of low cost,
simplicity and flexibility.
