wavelength can be stored in this product.
It is possible to output the stored waveform by selecting "Arbitrary" in the local mode.
* Do not turn off the power supply immediately after the completion of the transfer of data, because
the storage device processes data in memory for about 1 second.
* The arbitrary waveform that can be used simultaneously is shared by channels 1 and 2. It should be
noted that if an arbitrary wave of a different waveform is transferred from the PC during the
outputting of an arbitrary wave data, the channels will be switched over immediately after the data
transfer is completed.
