New FW release Version V1.4063, Ultra only Changes: - Option to sound a beep when the trigger level is exceeded. - New measurement: MULTI BAND - Waterfall height reduced. The multi band measurement allows the definition of up to 8 bands to be scanned, each with a possible trigger level The active bands will be scanned in the order as listed. As the scanning is intended to be as fast as possible the RBW and display points are automatically optimized for speed depending on the span of the band. There is not enough free memory in the 2.8" tinySA to add these functions. The wiki is not yet updated with this new functionality --

Erik,
I just started playing with the latest version. It appears that the
BIG NUMBER function has been broken.
With a frequency range entered, in MULTI BAND I just see a broken
horizontal line. With several ranges entered, the display flashes
between them so fast that it's almost a blur. What is the intended
use of this new mode?
And I didn't even know the Ultra has a beeper. I've never heard it,
and wonder what other functions use it.

Terry, Thanks, indeed, big number needs the large waterfall space, will revert back. The broken line occurs when very small spans are scanned. Will repair this. The multi band still needs to be matured. It comes from a request to allow a non continuous frequency range --

Hi Erik, thanks for adding new features!
I would suggest to add a new displayed plot variant for the muti-band mode: not to jump the scan from one band to another in a cycle, but rather to plot all selected bands simultaneously during a single scan (common screen).
Just add vertical separation lines between the displayed bands. In this display mode we might also add more flexibility in selecting common RBW settings, etc.
Thanks for Your work!

My preference would be to leave as-is, but with a 1 second delay between bands scanned. I think it would be too crowded with 8 segments side-by-side.

I must admit that I was expecting the sub-bands to be displayed all in one sweep, and was slightly confused when it cycled. So perhaps the option of either display mode would be possible?

All in one sweep is under development
Current mode will disappear? --

This is how it will look.  This will allow the usage of a low RBW to scan the relation between strong signals and very weak signals such as harmonics without having a very long sweep time --

? ?The mult-band scanning looks very useful Erik.? I expected it to be under the "FREQUENCY" menu, but the "MEASURE" menu also works.? Any chance in the future of also adding the option of manually specifying the RBW for each band? Some test standards require multiple frequency bands with different RBW's for each band (i.e., 30-200MHz @ 10kHz RBW and 200-1000MHz @ 100kHz). Being able to display the continuous 30 -1000MHz range using multiband scanning at the specified RBW's would be a neat feature. Herb

Till now I'v give each band the display points equal to its share of span. When each band has a different RBW (which is possible to implement) the amount of points will have to be split base on span AND RBW to ensure equal information density in each segment/band --

Erik, ? Does that mean that if 3 bands are selected then a complete sweep will be performed for each band, but the final composite display will consist of the top 450/3 points for each band? Herb

I see four options:
- Equal amount of display points for each active band
- Amount of display points relative to band span share versus total band span.
- Amount of display points relative to band span/RBW share versus total band span/RBW, this gives equal information over total span.
- Manual setting of the % of display points per band
I prefer not to implement all options...... 2 and 4 are my favourite as 2 is already implemented and 4 covers any crazy use case people can think of. --

? Your example display seams hard to interpret - especially since the frequency per division readout will be wrong. The display of even just four bands simultaneously would be confusing.? The multi-band mode on the SARK-110 works quite well by splitting the screen into four quadrants, each with its own kHz/div.

? ?Erik,
? ? ? ?Given the limited real estate at the bottom of the screen, perhaps you could get rid of the START, per/div, and STOP annotations and replace them with centered annotations for each band (i.e., 9.9 - 10.1MHz | 19.9 - 20.1MHz in your example) when using the multi band scanning mode.? Between centered band annotations and frequency markers placed by the user, the display should be easier to interpret without becoming too cluttered.

Another suggestion, as a workaround for a shrinked display issue with multiple bands, might be just to implement a double-click on screen to expand/collapse back the band of interest to full screen/ splitted display. This might solve the screen size limitations
BR,

Would it be possible to use two alternating colors for the trace so that the bands can be seen more easily?
|
The trace colours are orthogonal to the bands. The bands are separated with vertical blue lines
There will be more text info below the bands --
