Hey Jared,
Thank you for clarifying your needs on the burst transmit. Currently the ARB functionality allows you to set a period value of up to 64k (pattern memory of 2k I/Q) which depending on pattern length can get you close to the duty cycle you need. This is only exposed through loading a custom ARB file though, so I think we would need to expose the period setting through the software/standard mods at some point to be truly useful.
At this point, the BB60C is only going to run on USB 3.0. The architecture is such that it requires a host PC to perform the majority of processing. The device itself has little resources to do the processing required to turn IF samples into sweeps (FFTs), or decimate, and this is what is needed to reduce throughput to the PC. Look for future products to address this.
A side note, the USB 3.0 hubs we use in shop are these http://www.amazon.com/Belkin-SuperSpeed-USB-4-Port-F4U058tt/dp/B009AR2MD2. They let us connect and run up to 8 BB60Cs at a time off a standard laptop.
Regards,
A.J.
