I’m a bit new to using the EMC part of Spike. I have a BB60A and I need to measure a list of frequencies for Quasi Peak. Is there a way to create a list and load it and have the software measure them and report their values? Right now the only way I see how to do it is manually typing the frequencies and using the start/stop and loading the result list with the results. Is there a way to automate this? It would also be nice if you could do a peak scan and then have the software go back and automatically perform quasi peaks for the frequencies which are appear on the peak table. Is there a way to do this?

Currently there is no way to automate the quasi peak measurements. It must be done manually as you say. I think this is a good suggestion and it might be something we can add to our software in the future.
Side note: In addition to setting the QP frequency manually, you can select a spur in the peak table list and move the spur frequency to the quasi peak frequency entry with the “Selected Spur to Meter” button. You can do this while the QP measurement is active, and you can move the QP measurement to the meter readings table with the “To List” button while the QP measurement is active as well.
I apologize for the inconvenience. Thank you for the feedback.

Can you all please add this? The company just purchased a Siglent SSA3000 and their EMI tool does this. Also when I have been in EMI labs the SW pretty much did the same thing.. Find the peaks above a level and go back and perform quasi peak on those. The Siglent can not sweep anywhere near as fast but there are trade offs.
Thank you for the quick reply.

I also would love to see this feature being added.
Just did my first EMC pre-compliance experiments with my BB60A.
Doing QP measurements for the identified spurs needs a lot of clicks, especially when exporting the values for documentation.
My current workflow:
1. Sweep and identify spurs
For each relevant spur:
1. Use “Spur to Meter” Button to initiate measurement
2. Let it run for a defined time
3. Record values/Export screenshot of the bar meter
It would be so great to have a row in the limit tables to define a QP “sweep time” for each frequency range, so this could be fully automated.
Of course, CSV exports of the results would be very handy 😉

4 years later and this feature is still sorely missing. I’m sorry but this is the reason why I can’t recommend Signal Hound analyzers to colleagues and friends for EMC testing. Although otherwise I very much like the BB60C that we have…

Thank you for the feedback. I agree this would be a useful feature. Would a button that automatically performs the QP measurement on all current peaks in the peak table satisfy your workflow requirements?

the description provided by Manuel seems reasonable as first approximation. I’ll be doing more EMC testing early next week, I’ll be keeping notes for you and share them with you when the measurement session is over.
On a related note – ability to copy spectrum directly to my clipboard would be greatly appreciated as well. Now I use windows snippets, but if there was a shortcut that would put spectrum screen and possible peak table into clipboard(possibly a menu item that would appear after RMB click on the sub window?), that would be great.
