User Manual

Arbitrary Wave
The Arb signal consists of two types: the system’s built-in waveforms and the user-dened waveforms. Built-in waveforms
are stored in the internal non-volatile memory. Users may also edit the arbitrary waveform with 8 to 8M data points,
namely 8pts to 8Mpts.
8.1 DDS
Choose Waveforms →Page 1/2 →Arb →Arb Mode and select the “DDS” output mode. The parameters include fre-
quency/period, amplitude/high level, oset/low level and phase.
Figure 8.1 DDS
Frequency/Period Set the signal frequency or period; The current parameter will be switched at a second press.
Amplitude/HighLevel Set the signal amplitude or high level; The current parameter will be switched at a second press.
Oset/LowLevel Set the signal oset or low level; The current parameter will be switched at a second press.
Phase Set the phase of the signal.
In DDS output mode, users can set the frequency or period of the arbitrary waveform. The instrument outputs an
arbitrary waveform which is made up of certain points according to the current frequency
8.2 TrueArb
Choose Waveforms →Page 1/2 →Arb →Arb Mode and select the “TrueArb” output mode. The parameters include
sampling rate/frequency, amplitude/high level, oset/ low level and phase.
SRate/ Frequency Set the signal sampling rate or frequency; The current parameter will be switched at a second
press.
Amplitude/ HighLevel Set the signal amplitude or high level; The current parameter will be switched at a second press.
Oset/ LowLevel Set the signal oset or low level; The current parameter will be switched at a second press.
Phase Set the phase of the signal.
In TrueArb output mode, users can set the sampling rate (the output points per second) or frequency of the arbitrary
waveform. The instrument outputs an arbitrary waveform point by point according to the current sampling rate.
