Usage summary |
| -m <mode> |
Recording mode. Normally only
use 2 for "16 bit" modes or 3 for "8 bit" modes. 8 bit corresponds to
the normal recording rate of 256 Mbps. |
| -r <rate> |
recording rate (in
Msamples/sec). Default is 32. |
| -t <time> |
Recording time. Either the time
in seconds or total number of blocks to record (e.g. 10s is ten
seconds, 100 is 100 blocks). Default is 3600 seconds (1 hour). Time in
minutes or hours is also supported (e.g. 6h is six hours) |
| -s <time> |
Recording start time as fully
qualified UT date. Multiple data forms are supported and include
yyyy-mm-dd hh:mm:ss.s, yyyy-mm-ddThh:mm:ss.s, yyyymmddThhmmss.s |
| -w <bandwidth> |
Recording bandwidth. Defaults to
16 MHz. Should be a simple fraction of 16. (E.g 2, 4, 8) |
| -b <blocksize> |
Block size in bytes used for
reading from vsib and writing to disk Default is 32000 |
| -f <blocks> |
Amount of data to write
per file. Either in seconds of number of blocks (e.g. 10s is ten
seconds, 1000 is 1000 blocks). Default is 10 sec. |
| -o <filename> |
Filename prefix to use. The
dayno and time (in seconds) will be added to the prefix to create a
unique file name. Typically should use "Exper_ant", e.g. vt001d_Pa.
Defaults to "test". |
| -c <mode> |
Use to record packed data, in
which not all channels are recorded. Useful to reduce disk usage which
the user data rate is < 256 Mbps. This
should be a 4 character string, where 'x' signifies the channel
is to be recorded
and 'o' or '0' means not to record the data. 'xxxx' records
all data. 'oxox' will record every second channel (so dual
polarisation of a
single frequency for a normal VSOP recording mode). 'ooox' will record
only the first channel from the DAS. Current supported modes are oooo,
ooox, ooxx, oxox and xxxx (default). |
| -e <device> |
Name of vsib.o module device
file to read from. Defaults to /dev/vsib. |
| -l |
Loop mode. Overwrites the data
file eventually (??) |
| -v |
Verbose output |
| -help |
Usage summary |
| -p/-pps |
Check datafile for 1PPS markers
in the expected position (default) |
| -s/-stats |
Calculate sampler statistics for
each data channel |
| -x/-count | Check data from VSIC countdown
mode for consistency |
| -search <pattern> |
Search for the give pattern (in
hex) in the data files |
| -v/-vlba |
Data was recorded using VLBA
(rather than AT sign/mag) convention |
| -r/-rate |
Data rate (in Msamples/sec) at
which data was recorded. Default 32 Msps. |
| -b/-bits |
Number of bits per sample.
Defaults to 2 |
| -f/-fail |
Stop running after the first problem found in the data. |
| -V/-verbose |
Print more messages to the screen |
| -n/nbytes <n> |
Only analyze for first n bytes
(rounded up to the size of the internal buffer, so a value of 10 would be rounded up to 2e6). |
| -help |
Usage summary |
| -v/-vlba |
Data was recorded using VLBA
(rather than AT sign/mag) convention |
| -r/-rate |
Data rate (in Msamples/sec) at
which data was recorded. Default 32 Msps. |
| -n/-nlags <n> |
Number of samples to use in FFT
(number of spectral points is half this) |
| -C/-chan <n> |
Channels to analyse. Can be
specified multiple times (e.g -C 1 -C 2). Defaults to 1 |
| -b/-bits |
Number of bits per sample.
Defaults to 2 |
| -if1 <n> |
First channel in range to process |
| -if2 <n> |
Last channel in range to
process. E.g. -if1 2 -if2 4 is equivalent to -c 2 -c 3 -c 4 |
| -sp1 <n> |
First spectral point to plot
(default 1) |
| -sp2 <n> |
Last spectral point to plot
(default nlags/2) |
| -d/-device |
Pgplot device to use. E.g. /xs,
plot.ps/cps plot.ps/ps plot.png/png |
| -nint <int> |
Rather than average entire data
file, plot integrations of <int> seconds. |
| -pause |
Pause between plots if plotting
sub integrations |
| -V/-verbose |
Print more messages to the screen |
| -n/nbytes <n> |
Only analyze for first n bytes
(rounded up to the size of the internal buffer, so a value of 10 would be rounded up to 2e6). |
