Location and Time

Room: CC F326???

Time: 2pm.

Remote Connection

You can connect using BlueJeans using the meeting number 589 693 655 .       (Click "Expand" to the right for more details -->):

(if problems, call phone in conference room: 757-269-6460 might not be the correct number)

  1. To join via Polycom room system go to the IP Address: 199.48.152.152 (bjn.vc) and enter the meeting ID: 589693655.
  2. To join via a Web Browser, go to the page [1] https://bluejeans.com/589693655.
  3. To join via phone, use one of the following numbers and the Conference ID: 589693655
    • US or Canada: +1 408 740 7256 or
    • US or Canada: +1 888 240 2560

More information on connecting to bluejeans is here

Specific instructions for connecting via polycom:

  • Turn polycom on if necessary
  • With the polycom, place a call at 199.48.152.152
  • Press # to enable the polycom keypad, then enter the meeting id: 589693655 and #
  • You may have to unmute the microphone: #*4
  • Turn the computer on if needed

Agenda

These are not intended to be restrictive, but to determine how many bits are needed to pass the parameter values from the software library driver into the firmware.

Name Max value Comments
NW 1024 I think this is the current maximum
P1 7 Initial ped window length NP=2**P1 which would be 128 for P1=7
P2 7 Local ped window length NP2=2**P2 which would be 128 for P2=7
IE 1023 for the CDC we need IE > NW-NP
NPK 15 Lubomir is ok with max of 8; 15 uses the same # bits; can limit this to 8 in software
H 511 Hit threshold
TH 511 High timing threshold
TL 63 Low timing threshold
IBIT 7 Scaling factor for integral is 2**IBIT (using 4 for CDC & 7 uses same # bits)
ABIT 3 Scaling factor for amplitude is 2**ABIT
PBIT 3 Scaling factor for pedestal is 2**PBIT
