And now the 2 cent question :wtf: How can options be enabled on infinium scopes? :palm: If I look to what this guy did, he enabled all available options. :clap: All Enabled Options. 64MPts, EZJIT Plus, High Speed Serial, Low Speed Serial, Force 1G, User Def Fn, eGUI, Voice, Power, PRMLpro, PRMLpro 2, PMRLpro 3, PRMLpro 4, PRMLpro 5, App Remote, Gigabit Ethernet, DVI, HDMI, USB, Wireless USB, USB3 Compliance, Xilinx Probe, Altera Probe, Fibre Channel, CAN, FB DIMM, Express Card, SATA 1, SATA 2, SATA 6 Upgrade, SAS, DDR1, DDR2, DDR3, GDDR, GDDR3, GDDR4, GDDR5, MIPI, Display Port, FlexRay, My Compliance, AP3, AP4, AP5. Some options are officially not supported for this scope model. http://www.ebay.pl/itm/Agilent-54831D-MSO-4an-16dig-wUpgraded-Motherboard-cpu-2-3-2GHz-RAM-SSD-ALL-OPTS/291821246325 |

Of course that hack only works with 5.71 software, I am not sure that version works with the 54835/45/46? |

Got 64 MB of RAM yesterday, installed and seemed to work. Today I should have the replacement op amps in my hands. Also ordered regulator for 0.85V rail. Looking for 2.5" IDE HDD to install Win 98 (do not feel like installing on original HDD) and newer software. Also IDE CD-ROM drive is needed. Is there RS232/SPI/I2C serial decode option for early Infiniums? Or any other options apart from USB testing voice control? All the literature I have seen has been pretty thin on that respect. |

I hope that the new IC will solve your problem. I think power analysis software was available as well but you are right, there is limited information available about the options. |

So I had to get bit more. There is VRM (voltage regulation module) on motherboard, if 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 :) |
