HOW-TOs for testing guppi_daq and dspsr

source the venv and run

# monctrl@spare3

source /home/sandboxes/monctrl/sims/22.1/gbt.bash
source /home/cycspec/cycspec.bash

# this time use jb3 and databuf=1 

/home/cycspec/bin/dspsr.jb3 -cuda 0,0,0,0 -cpu 23,22,21,20 -cyclic 128 -minram 128 -E /users/rlynch/VPM/Test_Scripts/etc/AP.par -d 2 -b 512 -L 10 -O /dev/shmtest_pulsar -a PSRFITS -header INSTRUMENT=guppi_daq DATABUF=1

read the data at the same time that dspsr is running

# monctrl@spare3

echo MONITOR_CODD > /tmp/guppi_daq_control
# when done
echo STOP >  /tmp/guppi_daq_control

view the data (via Ryan)

Here are some commands for spot-checking PSRFITS data

1) log into your machine of choice (e.g. vegas-hpc21)

2) source /home/pulsar_rhel7/pulsar.presto3.bash

3) Find the output data

4) To view the integrated pulse profile, use 'pav -DFT <filename>'

5) To view the average bandpass use 'psrplot -pb <filename>'
