Plus, the fastest logging rate is 1\/s, so these channels are designed to look at slowly-varying signals. <\/li>\r\n<\/ul>\r\n\r\n<p> <\/p>\r\n\r\n<p>Here is the resolution for the RX3000 analog inputs. Most customers ask \u201dWhat can you read? I need to read 100mV\u201d meaning 0 to 100 mV. The 0 to 2.5V range is equal to 2500mV.
