I did measure an increase in waveforms/s with a faster processor. If you install a lot of memory (which costs peanuts anyway) you can disable swap which will also make Windows work faster. |

I hope that the new IC will solve your problem. --- End quote --- I could find a way to drop it's output voltage from 2.9 V to around 2.2 V I could fit much faster processor. Not that it would make much difference to scope performance I guess :) --- End quote --- A diode will do the job :) |

A diode won't work because it's forward voltage depends a lot on the current. Even a Schottky diode will drop close to 1V at higher currents. |

I got 1.5 GHz 8 GS/s scope for price of 4€ opamp 8) Now I can justify spending bit money to get second IDE HDD and CD-ROM for upgrade to Windows 98. |
