Phaser capabilities

Eliana

Hello,

I am already working with ARTIQ, and interested in maybe purchasing another-
this time with a Sinara 4624 AWG "Phaser".
I am trying to understand what this Phaser is capable of.
Is it actually an Arbitrary Waveform Generator (AWG) as in its name?
We would like to generate an arbitrary wave for a certain amount of periods,
and then change immediately to a constant high voltage.

Is this possible using the phaser? If so, how?
I read the sections in the manual about SAWG and the phaser,
and do not see how this can be done.

Thank you!

The Phaser hardware actually an AWG. But unless you intend to implement gateware yourself, you may be more interested in what the gateware and coredevice driver in ARTIQ do. The Phaser gateware currently does not implement uploading voltage-vs-time samples that it then plays back.
Supporting arbitrary things in software/gateware quickly becomes arbitrarily complicated and hence generally inefficient and limited compared to well-designed parametric approaches. That's an intrinsic property of "arbitrary".
The actual capabilities of the Phaser gateware and coredevice driver in ARTIQ are described in the manual.
https://m-labs.hk/artiq/manual-beta/core_drivers_reference.html#module-artiq.coredevice.phaser
If the current Phaser gateware/software doesn't meet your requirements or if you can't decide that based on the docs, the recommendation is to talk to write down your requirements accurately and quantitatively and then engage people who can help.

Thank you for the explanation!
