9.3 Connection to signal source
9.3.1 Typical setup
Figure 3 shows an example installation in schematic form. It is only one possible arrangement;
many others are possible. In this case thirty-two Faraday collector electrodes in a beamline
system are connected to the F3200E inputs via low-noise multi-way cables. In this example, a
suppression electrode is biased by the high voltage (HV) output. A loopback HV connection is
made so that the F3200E can verify that the bias is reaching the suppression electrode.
A pneumatic actuator which can move the Faraday collector array is connected to the actuator
connector. The general purpose I/O port is used to output an analog voltage monitor reflection of
the incoming signals, for viewing on an oscilloscope for example. The other analog and digital
lines can be used to control and readback other external devices.
A gate signal generated by a remote timing controller triggers the F3200E to measure data. The
gate out signal is available to synchronize other equipment to the F3200E acquisition.
The F3200E is connected to the host system by Ethernet in this example, and the fiber optic loop
master port is used to connect other Pyramid devices.
