Sam Test

The SamTest software records the sampler output to an Octave readable ASCII file. Below is the usage statement for the program.

usage : samtest [-a] (average the VFC values and the answer)
                [-b <number bins across pulsar>]
                [-c <cal switching frequency>]
                [-d <cal duty cycle>]
                [-e <epoch for pulsar period>]
                [-f <sampling frequency> (continuum mode)]
                [-g <phase for pulsar>]
                [-h] (this output)
                [-i <number of first VFC to sample>]
                [-l <plot data as collected>] (pulsar mode)
                [-k (Kill current Job)
                [-n <number of VFCs to sample>]
                [-o <filename>] (octave format output)
                [-p <pulsar period>]
                [-q <number of queries> (SCT testing option)
                [-r] (read the VFCs in reverse order)
                [-s <number of seconds to sample for>]
                [-t (secret test option)
                [-u <name>] (if your are not yourself)
                [-v] (emulate SP14M style sampling)
                [<ip address of SCT>]

 NOTE: This is a test program, use it at your own risk.
       some options may be broken or not worked as outlined
       above)

Example If you are interested in studying the noise properties of a given receiver at Mt. Pleasant of Ceduna and you can record the sampler data using the following command:

/obs/develop/telescop/sampler/samtest -c 0 -f 847 -i 0 -n 2 -s 300 -o /scratch/outputfile.oct sam26m

This will record the data from IF’s 0 and 1 from sam26m for 300 seconds (5 minutes), dumping the output to /scratch/outputfile.oct
