Future features in Spike

Hello,
Love the software, but would like to see some items for us TV engineers. Under modulation, 8VSB and then be able to look at the eye pattern and the constellation would be great. Spike overall works great for most of my applications!
Also, I’m using the older SA44 and not the SA44B. Should I upgrade or will this unit perform as the B model.
Thanks for some great products!

Hi Mike,

We very recently took a look at 8VSB and determined it would require additional work beyond our initial estimate. Additional algorithms would need to be developed to properly demodulate 8VSB. I do not think we have immediate plans to develop this as we are currently working on other projects but I will make a note that you are looking for this functionality. This is very helpful for us when we decide what to work on in the future. Viewing 8VSB would also require a BB60C as it is our only receiver with the necessary bandwidth to capture the signal.

The SA44 has only a few limitations compared to the SA44B. Most notable,
– the SA44B has a preamp
– improved spurious responses with the SA44B
– and sweeps speeds and available RBWs between spans of 200kHz and 200MHz. The SA44B will have faster sweep times and allow smaller RBWs in this range of spans.

If you have additional questions, let us know.

Regards,
A.J.

Hi Andrew,

I see this topic is about a year old, but I ended up here after a web search after not finding 8VSB in Spike (BB60C) and just wanted to add an another request for 8VSB. I understand it’s all about the effort vs. the number of customers that a feature would help. I hope enough people pop up looking for it that it makes it into Spike, as it would be very useful for some of us.

Thanks,
Peter
