Lab Brick Digital Attenuator (LDA)
----------------------------------
On Linux, you need to give your user access to the usb device.
You can do that by creating a file under /etc/udev/rules.d/ named 99-lda.rules
with the following content::
SUBSYSTEM=="usb", ATTR{idVendor}=="041f", MODE="0666"
Then you need to tell udev to reload its rules::
$ sudo invoke-rc.d udev reload
You must also unplug/replug your device if it was already plugged in.
Then, to run the Lab Brick Digital Attenuator (LDA) controller::
$ lda_controller -d SN:xxxxx
The serial number must contain 5 digits, prepend any number of 0 necessary.
Also, the "SN:" prefix is mandatory.
You can chose the exact LDA model with the -P parameter. The default being LDA-102.
