identify the LO power supply point and solder a small piece of wire to it (identified - see the arrow in the photo - is that point OK?).place the RF group on the table, with no connection (done).remove the lid from the RF group, paying attention to the rubber details that risk to fall when you re-move the lid itself (done).remove the RF group from the housing (done).I understand that I must do what it follows: I already read the documents above and I am going to do the first test, but I would like to have some help. The manual self-test (SHIFT/1) says that RF does not pass. The frequency is not stable and the trace drifts slowly toward left. Replaced the battery, it "seems" to work but really doesn't, because the trace (and the TG) is shifted about 20MHz toward left and the signal is 5dBm lower than real and noisy. I got for free an Advantest R3132 with TG. I revive this topic that I found very useful for me, hoping that someone is still there to give me some help.
