via the three pin mains power connector. It is of course important that
the power socket that you are using is well earthed.
The purpose of this ground cable to the Faraday cage is to provide an
easy means of grounding the cage — please note that it is not for
grounding the Picostat. If your Faraday cage is already earthed by its
own ground connection then you should not use this cable! Use of the
cable in this instance will provide a second pathway to earth which
could result in a ‘ground loop’ which can actually increase signal
interference! You can try grounding the Faraday cage via its own
connection to earth,
or via the Picostat ground cable — but not by both
methods simultaneously.
Connecting the Picostat
Your Picostat will have been supplied with an I
2
C cable (DB–9 pin
connectors at either end), and three cables with BNC connectors at
either end.
First make sure that the e-corder is turned off. Then connect the I
2
C
cable to the I
2
C connector on the back panel of the e-corder , and the
other the other end to the I
2
C Input connector on the back panel of the
Picostat. Use the three BNC cables to connect the back panel of the
Picostat to the front panel of the
e-corder as in Table 3–2 .
