Thanks some very good replies. I did not try the input panel as I just assumed it was not supported as the the fine rotary adjustment only worked in 0.1mhz steps.
Yes very correct in having to learn the characteristics of any new test equipment they all have there quirks. I have to admit for much of the work I do a simple anolog scope and spectrum analyser are my tools of choice. And 10 years practice with the Tek Tds2022.
Given my other mistakes and assumption can the text font size be increased ?
It looks good on your pictures but my nose would be touching the screen to get that type of close up
Yes I did try the brightness control and thought it was a bit disappointing. The text can be made very bright but the waveform was quite dull when in single and normal. Infact when the scope did trigger the short pulse was entirely masked by the vertical centre graticule and I had to move the position control. I think the trace brightness and text and graticule would be better with separate control. I honesty cannot remember if this was the case for the Siglient.
The yellow measure text for trace one at the bottom of the screen was very hard for me to read. Other colours may be better.
Anyway I'm just wining - it's a great scope for the money and the front panel layout and controls are top drawer

Text size can not change. (at this time)
And and also I hope some improvement in this. I'm well over 60 and my eyes are not young man eyes at all.
But how to improve it, it need think carefully how to improve visual ergonomics for different situations.
It is not only because different eyes including more or less severe color blindness but also different environment. School class room and astronomic observatory with optical telescop with dim red lights or dark are different etc.
I have many times thinked that user need access to all colors. Just like in old color CRT Rohde&Schw. where user can select traces, graticule etc all colors separately just as he want. Need only one table in setting menu where user can free select colors just as he want.
And this is not even difficult.
Font and size need perhaps more designing and optimization.
Graticule and trace brightness settings are separate, you can turn graticule from blank to high bright.
Mostly, trace brightness is ok in default 50%. This give best scale for intensity gradation. But it is not always best. Example these 1s period narrow pulses. If look these in roll mode example 1s/div (peak mode on also trigger auto for smooth scroll) there optimum is 100% trace brightness. For very fine lines (specially vertical peaks in some cases) it is good to adjust graticule brightness to more low, say example to 15-25%. Or change graticule style.
Some times I do not use channel 1 as main channel if I use SDS2k. In some cases visibility for MY individual eyes is perhaps better with other channel color.
I have "40 -80 cm" distance glasses for lab use. If I use normal "read" glasses they are too close and if normal car driving glasses, they are terrible for close. Many times I need take glasses away for close. But, then it is too close. So I need "lab" glasses. Never want "multi distance" glasses.
Oscilloscope and other equipments designers are many times "young mens and womens" who do not understand anything about human eyes and visibility. Extra problem with chinese are that they are not familiar with our abc reading at all. They do not understand what is "font" and how we perceive the text in western world. They have born to chinese text and they can perceive cinese text. Turn your scope to chinese language and perhaps it is good and easy read (for them). This is same thing what is with big and small letters.
One difficult thing to chinese is text font and next is big and small letters. But for font, no one can tell them what is right and what is wrong. If they think chinese language and its "fonts" oh well then they know how important it is but with they own eyes... all western looks same... just as we look chinese.. chinese text looks chinese text and we do not often think what is this and that "font" in chinese text. If take some "old" chinese font, most chinese can not even read it. But western people can happy put it to his equipment and tell to chinese you can select also chinese language. (then they wonder what stupid font this western manufacturer use)
This font "war" and hassle have been as long time as I have seen chinese equipment data sheets, text in equipments menu, user manuals and so on. Perhaps one reason is also mr Microsoft who set "default" fonts in some softwares. What a mess.
In this image trace brightness is 100% and graticule (if I remember right 20%) lower than 40% default.
