![]() At the current state, I am no longer able to get the FREQ CAL. While the intermediate steps with measurements showed improvement, I never got the device to pass the AMPL CAL. The AMPL CAL always failed and I did try follow the service manual to tune the chrystals. I know, sounds strange, but worked for a few weeks. After running FREQ CAL this way once, I was then able to run FREQ CAL properly with the CAL OUT connected from start. This allowed to pass the first two steps of the frequency calibration routine and after that (a few seconds), I would plugin in the CAL OUT again. I was in some case able to carry out the FREQ CAL routine using some different input signal (actually my DVB-C band from my TV provider). The device works as it is, but all frequencies are about 34MHz wrong: for example, the local DVB-T transpodner at 754 MHz shows up at 720 MHz. It went suddenly out of calibration and shows corresponding error when booting. Hello, One of my HP 8594E has developed a problem.
