[casper] ROACH 1 root file system image

Hello All, I hope everyone is well. Does anyone have a backup of the UBOOT disk image for *ROACH 1*? The link that previously hosted the image is now dead, my backup file is corrupted it seems. Thanks a Million, Colm -- *Dr Colm Bracken* Lecturer Maynooth University Experimental Physics

[casper] PFB (taps): Effects on time resolution

tap PFB, am I essentially smearing out my time resolution by a factor of 8, since I am now summing 8 rows of my 1024 point time streams? I can't see how the number of PFB taps wouldn't affect my time resolution. Or am I missing something? Thanks in advance, Colm -- *Dr Colm Bracken* Lecturer

[casper] SRS FS725 Frequency Standard

Hi Francois, Thanks for the feedback. I guess I could have phrased the question a bit better; so our current sample rates are 1 Gsps (on ROACH 1), which we will mix-up to 4 - 8 GHz with a LO. However, in the future, when we move to higher sampling rates (and possibly beyond 8 GHz IF) I wonder
