Just wondering what the effects of having a long cable (3')between duplex out and antenna in would be. I get 3 failures running this test. all 3 are "suspect receiver assembly (low)" I wonder if the long cable attenuates the signal to the antenna in port and is causing the failure???
As far as I know, this test cable needs to be short low loss cable. Your receivers sensitivity might be at the edge of passing or failing. 3 feet and lossy cable will fail your test at the higher frequencies. I haven't tried using a longer cable since it is recommended using a very short cable. Try with a short cable and see what happens.
Hello, here from Brazil! I need help. Do you know if there is a way to self-calibrate this service monitor? If so, could you help me with how-to information?
As far as I know if any or some of the functions are out of specs you will need external sources to calibrate. Here is a good source to find more info. www.eevblog.com/forum/repair/hp8920a-communications-test-set-repair/
