Similarities/differences between BB and SA series

Hi,

I’m having a hard time figuring out exactly how similar/different the BB60C and USB-SA124B are, and how those differences manifest in the Spike software. The feature lists look completely different, and yet they can both become half of a Scalar Network Analyzer? What’s going on? I’d strongly suggest a side-by-side comparison table between the two.

In particular, the USB-SA124B has a “High Dynamic Range Measuring Receiver”. Does the BB60C not have this? How does this manifest in the Spike software?

The BB60C has “Digitized IF Data at 80 million samples per second”, whereas the other has “I/Q Data up to a 240 KHz bandwidth”. So does the BB60C digitize a single, image-rejected sideband, whereas the SA-124B uses the I/Q method?

I could go on, there a plenty of other differences in the feature list that are difficult to pair off. Any advice to clarify all this would be greatly appreciated!
