Hello Rainer,

I helped with the RFI/EMC design on both those products here in Colorado
Springs and I will try to help answer your questions regarding the vertical
accuracy.

For the 54501A Scope...         

The vertical gain accuracy (dc) is +/- 1.5%
The offset accuracy is +/- 2% of offset + 0.2 * (V/div)
The vertical (A/D) resolution is +/- 0.4% (8 bits)

The worst-case voltage measurement accuracy (using cursors) is the sum of
the above three percentages.

The time base accuracy is 0.005%.

 
For the 54601A Scope...

The vertical accuracy is +/- 1.5%.  The cursor accuracy is +/- 0.5% of
full scale or +/- 0.5% of position value (single cursor). For dual cursors,
the vertical accuracy is +/- 0.4% of full scale.

The horizontal (time base) accuracy is 0.01%.

------------------------------

All the above data is from our spec sheets on these two products.  I believe
(I know, I'm biased!) that you will find these accuracies comparable, or
better than other brands.  We have some other data on single-event pulse
captures (single-shot signals) comparing HP scopes with other competitors
which indicates our superior waveform integrity and jitter responses.  If
you, or anyone else, would like literature on these scopes, please leave
Email.  Also, Rainer, if you would like a tour of the factory, let me know
and I'll be happy to arrange it.
