To Set an Arbitrary Waveform

The Arb signal consists of two types: the system‘s built-in waveforms and the

user-defined waveforms. Built-in waveforms are stored in the internal

non-volatile memory. TrueArb output mode allows creation of arbitrary

waveforms that contain from 2 to 20 Mpts.

TrueArb

Choose Waveforms → Page 1/2 → Arb → Arb Mode and select the “TrueArb”

output mode. The parameters include frequency/period, amplitude/high level,

offset/low level and phase and interpolation.
