"""capture test. assume transient has been pre-configured
acq400_capture UUT1 [UUT2 ..]
where UUT1 is the ip-address or host name of first uut
example test client runs captures in a loop on one or more uuts
pre-requisite: UUT's are configured and ready to make a transient
capture
eg clk is running. soft trg enabled
eg transient length set.
loop continues "forever" until <CTRL-C>
.. rst-class:: hidden
usage: acq400_capture.py [-h] [--soft_trigger SOFT_TRIGGER]

uuts [uuts ...]
run capture, with optional transient configuration
positional arguments:
uuts uut1 [uut2..]
optional arguments:
-h, --help show this help message and exit
--soft_trigger SOFT_TRIGGER
