Outline:

host_demux.py Demux Data on HOST Computer

• data is stored locally, either from mgtdram/ftp or fiber-optic AFHBA404

• channelize the data

• optionally store file-per-channel

• optionally plot in pykst

• @@todo store to MDSplus as segments.

example usage:

./host_demux.py --save=DATA --nchan=32 --nblks=-1 --pchan=none acq2106_067
    # load all blocks, save per channel to subdirectory DATA/data_CC.dat

./host_demux.py --nchan=32 --nblks=4 --pchan=1:8 acq2106_067
    # plot channels 1:8, 4 blocks


./host_demux.py --nchan=32 --nblks=-1 --pchan=1,2 acq2106_067
    # plot channels 1,2, ALL blocks
    # works for 8GB data, best to LIMIT the number of channels ..

./host_demux.py --nchan=96 --src=/data/ACQ400DATA/1         --egu=1 --xdt=2e-6 --cycle=1:4 --pchan=1:2         acq2106_061
    # plot AFHBA404 data from PORT1
    # plot egu (V vs s), specify interval, plot 4 cycles, plot 2 channels
    # uut

use of --src
    --src=/data                     # valid for FTP upload data
    --src=/data/ACQ400DATA/1        # valid for SFP data, port 1
    --src=afhba.0.log               # one big raw file, eg from LLC

./host_demux.py --nchan 128 --pchan 1,33,65,97 --src=/path-to/afhba.0.log acq2106_110
# plot data from LLC, 128 channels, show one "channel" from each site.
# 97 was actually the LSB of TLATCH.

host_demux.py [-h] [–nchan NCHAN] [–nblks NBLKS] [–save SAVE]

[–src SRC] [–pchan PCHAN] uut

host demux, host side data handling

positional arguments: uut uut

optional arguments: -h, –help show this help message and exit –nchan NCHAN –nblks NBLKS –save SAVE save channelized data to dir –src SRC data source root –pchan PCHAN channels to plot –egu EGU plot egu (V vs s) –xdt XDT 0: use interval from UUT, else specify interval –double_up Use for ACQ480 two lines per channel mode

if –src is a file, use it directly

dir/nnnn

if –src is a directory, first check if it has cycles:

dir/NNNNN/nnnnn*

else iterate files in dir

dir/nnnnn*

TO DEMUX ON WINDOWS TO STORE CHANNELISED DATA:

python .host_demux.py –save=1 –src=”[dir]” –pchan=none acq2106_114

Make sure that the muxed data is in D:[dir][UUT name]

Where [dir] is the location of the data.

Demuxed data will be written to D:demuxed[UUT name]

To plot subsampled data on windows:

python .host_demux.py –src=Projects –nchan=8 –pchan 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16 –plot_mpl=1:1000:1 acq2106_120
