| Conversion of 500MHz TDS744A to 1GHz TDS784A |

Not surprising. R1064 should be installed. The other three should be removed. ;) |

TDS744 (without "A") firmware v.1.0e Options 13, 1F,1M, 2F All combinations of resistors are tried, no result. It looks like I should change the firmware. On what to change and where to look the instruction? What is the difference between TDS744 and TDS744A? There were 3 lintels - R1061, R1062 & R1064. All 16 combinations are checked, no result.

Vlad_01 I have the same problem. Have you find it out? What are those configuration 0 resistor are for at tds744? I removed the capacitors anyway. |

I think removing the caps and installing R1064 only will let the scope sample @ 4GS/s on 1 channel and 1GS/s on four channels simultaneously, but it will still say that it's a TDS744. |

I got it. Is it possible to modify the firmware? Is that in the NVRAM. Have you replaced it or saved it? To prevent future problems. Thanks. |
