Hi Eric, following your progress, but no time to test on my unit. Usually using Anaren DBM to extend range up to 4 GHz by mixing ;) |

Great work, congratulate :clap: Assuming you gained full functions as described: http://rltechnical.com/_sample_files/sample_indesign/L4600A_technical_overview.pdf Except hardware option -> L4600A-530 5-pin Connector with FM Audio Demodulation Out (Voice Out) Top limit in document is still 2,7 GHz? Do you have now signal generator functionality from 2 MHz to 2,5 GHz ? In case of all answers are YES, just need one step by step instruction set for dummies to run up my E7495B :popcorn: Regards Djani |

Looking from the side, the only real gain is that (for E7495B) additional FM modulation option? |

The big brother N1996A only required an edit of text based files to extend the gen frequency range. Is there a block diagram of the entire 7495 - that should show us if hardware is present to gen below 375 MHz. |

Hi Eric, I can imagine two ways to recover the DSP firmware. 1) To dig into the bootstrap procedure for the SHARC. Maybe this can be done by reverse engineering the replaceTrashedRunCode. Also it might be possible to find some clues in the SHARC manuals. 2) To recover the DSP flash directly. I'm pretty sure there should be a JTAG connector on the DSP board which can be used to access the flash. Here's the picture of the board: https://www.ebay.com/itm/Agilent-E7495-63015-E7495-20015-990075-101602-REV-103-Board-Assembly/284074186099 I don't understand what you mean by "mounting" serial ports. "mount" is the term which is only used for filesystems. |
