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
eg clk is running. soft trg enabled
eg transient length set.

loop continues "forever" until <CTRL-C>

usage: [-h] [--soft_trigger SOFT_TRIGGER]
                         [--transient TRANSIENT]
                         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
  --transient TRANSIENT
                        transient control string use commas rather than spaces
