I am looking for a MAINTENANCE manual and/or schematics for the IFR 2399 Spectrum Analyzer. I have the Operations and Programming manuals. I would prefer a PDF. I am tracing down a fault in either the Tracking Generator module (most likely), or possibly a failure in the YIG signal from the RF module feeding the TG. I do not have access to another spec analyzer at this time, especially not above the 3Ghz range. Any help/advice/half-hidden pointing fingers would be appreciated. - tiredtech
UPDATE: I understand that this unit originated from LG in Korea and was rebranded by IFR. Can anyone give me any more information? A basic scouring of the internet hasn't turned up anything about LG's test equipment or any documentations. The IFR also closely resembles the LIG NEX1 NS-30, but a search for info about LIG and it's test equipments also turned up little (except for sales pitches for new equipment) Again, any help is appreciated. - tiredtech
