[ARTIQ] duty cycle management

2015-03-17 Thread Gaebler, John
Hi, It seems to me that in all cases the experiments can be pre-computed and then loaded onto the fpga in the normal way. As with the example that Joe gave before, you just have to add an else statement (or another if that captures the other possibilities) at the end of the experiment for

At present Quantum II does not do duty cycle management on its AOMs because its less cumbersome (given the existing .dc language) to transform AOM-induced beam pointing into amplitude noise using a fiber (and then noise eat downstream). This approach wastes laser power and is a patch on the

[ARTIQ] Installing and trying ARTIQ is now easier

2015-02-18 Thread Gaebler, John
Hi, We are able to flash the Papillio Pro from a Linux virtual machine with Migen, ARTIQ already installed ect. using 1. wget http://m-labs.hk/artiq/binaries/binary_package.tar.gz 2. tar xzf binary_package.tar.gz 3. cd binary_package ./flash.sh -a (notice the .sh) Is there a way to do this

[ARTIQ] GUI: controls

2015-01-30 Thread Gaebler, John
Hi, Could you explain how to run the example files for the GUI? I'm using the virtual machine from Joe Britton made on 1/20/2015 and I am able to run the flopping_f_simulation.py and flopping_f_siumulation.gui.py files. How do I create/run an instance of the experiment or the GUI? Thanks,

Re: [ARTIQ] Implementing a saveion function

2015-01-13 Thread Gaebler, John
It is possible to use at() to start each iteration at a specific time. Would that solve the duty cycle problem? I'm not sure what you have in mind there exactly. It wouldn't be optimal to slow down the main scan by a bunch to account for the possibility that saveion might run. I guess it

[ARTIQ] PDQ driver

2014-10-20 Thread Gaebler, John
Quick question, are we planning to support the old (Ryan's) PDQ firmware or just the new one. Would there be much difficulty in supporting both? I have started implementing the PDQ2 driver and made some changes to the transport example. Please have a look. I have some points I'd like to
