Last Week's Work
Worked on the setup to mitigate timing issues arising due to the non-synchronization of clocks of the Frequency counter and Raspberry Pi .
Took measurements with the mentioned setup and generated PSD plots of the FC.
Completed the setup for phase measurements by using an external ADC.
Work Plan for this Week
Complete the installation of the Mini Circuits Frequency Counter on the EPICS. This involves installation of EPICS base on Raspberry Pi, creating an IOC server on the R Pi and writing the data from the FC into a specific IOC channel.
Complete phase measurements and obtain the delay in the FC thus completing the characterization of the FC
Install the FC at a suitable place inside the 40m so that the beat note system can be remotely managed from any of the Control computers thus effectively replacing the spectrum analyzer(This will be done with
once the recently ordered FC is shipped)
Inside the 40m
I will be going inside the lab today around 9 am with Manasa to make a plan about where the FC must be placed and the routing of the RF cables and the cables which run into computers from the FC.
nce the channel is created and tested, we will install the FC inside the lab possibly by the end of this week or by next week
