General Description:
The Euvis AWG872 module generates dual arbitrary CW waveforms with sampling rates up to 8 GSPS. The on-board SRAMs provide up to 8M x 11-bit data memory to each channel. The AWG modules can be controlled by a PC via a USB interface. The sole RF input is a single-ended 4-GHz clock source CK with minimum power of 12 dBm. The RF outputs of the module are comprised of two pairs of differential analog outputs, with 50-Ω back termination. The module accepts a high-speed trigger signal and generates synchronization outputs and three programmable marker signals. The waveform generation can be in continuous or burst/pulse mode. The waveform contents can be dynamically changed using the user page selection. Programmable profile option facilitates compound waveforms. The companion API provides an interface for software development.

Programmable Profiles (*option)
In normal burst mode, the AWG can only output one waveform specified in the user page for each trigger signal. To change the waveform, users have to set the user page in the operations. Setting the user page or other relevent parameters may not be practical for tight timing and sophisticated waveform sequences.
With programmable profiles, users can specify user page sequences, loop counts, and auto trigger periods in the "Programmable Profiles" dialog window in the GUI or by API methods.
Each separate waveform is downloaded to separate user pages and the sequence in which the waveforms are
output is defined in the "User Page Sequence" textbox at the top. In the example above, the sequence
of waveforms would be Userpage 0, Userpage 2, Userpage 1, Userpage 0, Userpage 2 and so on.
Users can also define the loop count for each trigger signal. The loop count sequence is defined in the "Loop Count Sequence" textbox. In the example above, Userpage 0 will loop 3 times back to back for the first trigger signal, then Userpage 2 will loop once for the second trigger signal, and finally, Userpage 1 will loop twice for the third trigger signal. The number of loop count sequence does not necessarily have to match up with the number of user page sequence. For example you can have a sequence of 3 user pages but you may only have 2 loop count sequences. If the Loop Count Sequence was defined as "3,1" in the above then Userpage 0 will loop 3 times back to back, then Userpage 2 will loop once, then Userpage 1 will loop 3 times, then Userpage 0 will loop 1 time and so on.
The third profile is for the auto trigger period. In normal operation, auto trigger period is a constant, which is specified in the Auto Trig textbox. With the programmable profile option, users can program the periods of auto trigger signal to match the timing requirements for compound waveforms generated by the userpage and loop count profiles.
The image below shows a graphical representation of the waveforms depicted in the GUI screenshot above.
The GUI screenshot below demonstrates a different programmable profile. For this profile, you will
notice that there are 3 user pages but only 2 values each for the loop count and auto trigger sequences.
For this example, the Userpage sequence will be: Userpage 0, Userpage 2, Userpage 1, Userpage 0, Userpage 2,
Userpage 1, and so on. The loop count sequence will be: 3 loops, 1 loop, 3 loops, 1 loop, 3 loops, and so
on. The auto-trigger period sequence will be: 100 us, 60 us, 100 us, 60 us, 100 us, and so on.
