I find DC on the APC 2.4 J1 output connector of this 10 Mhz- 40 Ghz plug in for the old 8350B sweeper. On the other multiband plug ins (83592X, 95X...) there is a DC block inside the N or APC 3.5 output connector J1. There is nothing about neither in the manual nor in the CLIP. Wrong output connector ? Thanks.
