Markers use etc

[SM6EHY]

Hi, after operating a number of network analyzers from many manufacturers during the last 30 years, this software seems not to include at least one function that involves markers.
1 Fixed marker ZERO. The graph is reset to show all datapoints in relation to this specific marker dot.

2 Graph ZERO. The entire graph of interest is set to zero. All datapoints are set to zero. Most useful when you try to evaluate small differencies along the frequency axis. You use an attentuator in series that has not a flat response... Example is -1dB point, -3dB point from the reference graph.

3 GUI. The graphical user interface that worked out to be most useful, is the one used on Hewlett Packard - Agilent - Keysight analyzers. (What I gather this is not patended.)
The workflow is supberb, and you easily will find and use the most necessary functions. Maybe can be editable for your specific use ?

4 Display Line. Be able to set a line of GO / No Go on the graph of interest.

5 Master calibration. Be able to do only 1 (one) calibration with the current adapters etc with Maximum number of point (10.000 ?) and sweep type (log or lin), and then be able to narrowing to your specific frequency segment of interest, without loosing the done calibration. This calibration should be done with a stable environment, Temperature, Low- or No-flexible cables. This should be ensured for to rely upon your calibrations for days in a row...
This calibration can take some minutes to perform, dependant upon the sweep points. But you do not need another calibration done in near future with the same setup.

6 TX power ramp up / down. When you intend to evaluate an amplifier it is vital to evaluate the -1dB or -3dB pont.

Any comments ?
