How to recover/go from WP950 Memory Option M to L? And then to WPVL?
To my standard WavePro 950 I added the key for Memory Option M and that worked well, the specified 4M sample memory is available for use. Very pleased with that result.
But then adding the key for the L Option does not result in the expected additional sample memory. In fact it reverts to the Standard max of 1MS, even though the option "WPL" is in the scope's System list (and "WPM"" is still there, too) and the even though the Horizontal Setup menu allows 16M to be specified as a maximum value to use for "Record up to...", but no more than 1MB of sample memory ever displays as available at the top of that menu.
Also tried going straight to WPVL so that it became the only memory option in the System list (had removed WPM prior), but with same result as WPL above (limited to 1MS).
What is the magic formula/sequence of adding keys to go from WPM to WPL and then to WPVL on this scope? Would to hear from someone who knows, thanks.
