zed dez. thanks for the advice not sure if your aware but the 2399 has an extra rf lead to the top of the synth module and as there is no manual available I have no idea what it does, my friend recently dropped off his anritsu spectrum analyser for me to use to find the faults as it goes out to 6ghz. I will have a look at the yig at the weekend and see if I can see anything loose, not hopeful on finding spares. have tried to find a company in the uk that can handle repairs but no joy, its such a nice machine would hate to scrap it. cheers |

Hi all The 2398 is a LG (Korea) re badged product, not an IFR/Marconi. I believe there is NO support for them now, what there was was a module changing service and the faulty modules went back to LG for repair. What was Marconi/IFR/Aeroflex/Cobham, is now Viavi solutions Ltd who are only interested in 5G cellular equipment I have the service manual for a 2399 which should be similar, but it is a module change manual and probably not much help. 73 George G6HIG |

Hi All. Did anyone locate a copy of FCAL2398 - cal backup/restore utility? Thanks! |

Hi all, I have acquired a faulty IFR2398 and after some searching online I found this old thread. The symptoms are similar to those described by others (level fail, the built in cal signal is -42 dBm and external signals are over 20 dB less than expected). I suspect at least one fault at the front end as the SWR looking into the input is 4:1 or worse, which is really unlikely for an instrument like this. Has there been any other development other than those described in this thread? cheers Dimitris |
