But, I didn´t see any difference between this way and the PCB solded for a 10e12 ohms input inpedance. I think is because the good quality of the PCB and the sold.Carloshttps://www.blogger.com/profile/09088461044248860193noreply@blogger.comtag:blogger.com,1999:blog-1033721154498518542.post-20985944229931236182010-06-04T05:05:49.851-03:002010-06-04T05:05:49.851-03:00I have had a lot of trouble with the connectors as...I have had a lot of trouble with the connectors as shown. It is hard to measure 10e12 ohm. I measured the connector alone at about 10Gohm.<br />What brand/type of connector is it?<br />The guards around the Hi Z terminal are very important.nicskyhttps://www.blogger.com/profile/11438760170093563251noreply@blogger.com
