| 説明 | View of two isolated channels (of eight) seen from the digital end looking towards the back face of the analog inputs. Each channel is a differential analog sampler electrically isolated from its neighboring channels. A third banana jack in basic black for the common connection is centered below the red jacks, hidden behind the shielded segment.The shields were added when it was discovered that a large signal inserted into one channel could influence an adjacent channel. There are more subtleties in good instrumentation design than one would imagine.The triangular layout was chosen so that a standard dual-banana connector could be inserted either across the plus/minus pair, or between either plus or minus and the common.If I remember right, the big blue block is the data isolation, and the black block is an isolated power supply.The flying yellow capacitor in each channel can be seen here along with the rest of the ECO of which it is part. Another view of the whole board is here as well.Taken with a Sony Mavica CD-1000, with a Hoya +1 closeup lens added to the front. This was a 2 second exposure so the aperture could be small enough to get some depth of field. There was no cable release for that beast, so the self-timer was used to release the shutter. |
