Arbitrary/DDS Channels
You can generate a digital pattern for the analog waveforms of channel 1
and 3 (ArbStudio 1104 only).
Digital pattern generation can be used to test digital devices such as serial
and parallel DACs or to emulate protocols.
The 16-bit digital representation of the waveform samples is available on
the digital output connectors Pod A for channel 1 and Pod B for channel 3
(ARBStudio 1102D/1104D) as a digital pattern. The data is available after
some sample clock pipeline delay.
It is possible to set the output voltage level for digital pattern in the 1.6 V –
3.6 V range.
Pattern Generator
If the Pattern Generator option is enabled, you can set the output voltage
level for Pod A/B in the 1.6 V – 3.6 V range. The default value is set to 3.3 V.
NOTE: When the software is first loaded, the digital pattern generation is
disabled.
