RPNers are people of very few words
Yes
Or maybe no...... as bd showed... accidently when his example used exactly the same number of keystrokes
Yes that was indeed a cock up on my part
I am awake now
The majority of performance benefits come from much more complicated things such as the example bitseeker suggested. But the real power is in the ability to store keystrokes as programs and execute them on the fly. For example The AD8307 power meter calibration I have was done using the calculator's linear regression ability. So the power meter calibration values were loaded into the stats registers while I was actually doing the testing. Then a linreg was applied and the m and b values stored in persistent memory. After that it's trivial to write a program which does the conversion from volts to dBm resulting in:
2.015 XEQ P (this returns the power in dBm for the input voltage 2.015)
XEQ W (this turns it into watts in engineering units)
That saves a whoooooole load of work.
One strike and it's out?, if you're going back to a Rigol DS1054Z again , fix the TDS210 and keep as a backup because it wont be long before the Rigol goes and you can then get back to your "All the scope I need" TDS210. On the other hand, you can enter the great Keysight giveaway and every day there are 4 scopes being given away.
I've been hammering that keysight giveaway as usual. Nothing yet!
The TDS210 is a very very good scope and certainly is all I
need. Alas time isn't friendly and money is at the moment so it's about trading some convenience and the ability to proceed on motivational projects here because it's bust. You can't buy a trustworthy scope from ebay and get it next day.
More from Marc and the Apollo Guidance Computer. Some good HP and Tek pr0n too.

AGC implementation always fascinated me. It pushed through a number of difficult barriers on the enginering front.
