Hacked the DSA back in installed sucessfull with FW 1.08 with riglol (I did not soldered nothing on the unit): 1 - AAAB - Tracking Generator (do not enter it, already active by default) 2 - AAAC - Advanced Measurement Kit 3 - AAAD - 10Hz RBW 4 - AAAE - EMI/Quasi Peak 5 - AAAF - VSWR Oh wait the 3- 10Hz is no more there, I got a new option SSC-SDA to activate.Īny suggestions? Just to clarify, I have an older 1.03 bootloader and currently run 1.06 f/w (on a 0.04 mainboard). I have a: Main Board 00.04 RFB FPGA 00.05 DB FPGA 00.05 Boot 00.01.03 went from FW 1.09 to 1.18 and only the SSC-SDA option is not active, the others are still there. FYI, long time not here so I don´t know what the current state of the hack is. You will find the Front-End through the last IF (DSP) active, PIN diodes, and Mixer components (with Manufacturer and P/N) for the the DSA815 with Main Board up to v. You will be able to construct it yourself if needed, as I described it clearly in order of signal flow from SA Input through the Last IF (DSP Input). I didn't provide a schematic or block diagram (I could have) just because I didn't need any except for my personal hand sketches I made while tracing it out.
This architecture is valid for all versions of the DSA815s with the different Main Boards. This describes the IF Frequencies, Mixers, LO Frequencies, the on board LEDs that tell you which LO is currently active, etc.
