quadrature of a signal (without adding the half
quantum of noise that comes from the so-called standard quantum limit for a
phase-preserving amplifier) can be used to improve astronomical interferometry.
If anyone has any ideas about that, please let me know.

Dear All,
Is someone familiar with adc2x550-12 ?
Is there a yellow block of this kind of ADC for ROACH2 or SNAP platform?

Hi,Jonathan
This is the problem,I am using a passive divider used for RF signals.
I also find a link in casper website:
https://casper.berkeley.edu/wiki/16_way_1PPS_driver
The 1pps is called for a special divider.I will find one.
Thanks for your help!

Hey Peter,
I'm bumping this up to the listserve.
I am unfamiliar with PAPER. Perhaps someone with that project can help.
If you haven't yet, you should complete Tutorial 2 with your

hi all,
Can someone tell me what is the use of the aux_sync_out ?This is the
aux_sync_out cable from J11 on the Roach2.The J10 is for the aux_sync_in,all
this from the all roach2s can be put into a sync singal like 1pps.But what is
the J11 use for?
Best regards!

Hi,
The on-board LEDs for ROACH 1 seem to be mapped to the ROACH:led GPIO
block in Simulink, with bits 0-3 valid choices.
What is the Simulink mapping for the LEDs that are connected to header
cables that lead to 8 LEDs on the front of the ROACH Motel?
Thanks,
