4.2.3 Connecting the HF Cable
The flow cell is connected with the evaluation unit via the HF ca-
bles. Two different options are available:
Version 1: 1 x HF cable quad and 1 x N-connector
Version 2: 2 x HF cables (as signal cable)
1 x HF cable (as reference cable)
The decision for a certain cable version is taken by Berthold Tech-
nologies in the planning stage. It is subject to the application and
the desired distance between evaluation unit and flow cell.
Prerequisite for a correct measurement is the correct installation
of cables! Please keep in mind:
TIP
Make sure the cable does not get into contact with hot pipes
over the entire length (corrugated tube and single cable section
after splitting), e.g. direct contact with the device wall (not in-
sulated). This will ensure that all individual cables are exposed
to the same ambient conditions and that the compensation of
the cable drift works properly.
Never bend the HF cable! The bending radius should not be less
than 100 mm. Fix the HF cable with cable binders or other suit-
able means, so that the cable cannot slip anymore!
Version 1 The HF cable quad and the HF connectors on the evaluation unit
are labeled. Connect the flow cell to the evaluation unit as
shown in Figure 4-4; only cables with identical labeling can be
combined. The two connections on the flow cell are not labeled,
the assignment of both cable connectors M-Tx and M-Rx is arbi-
trary. Connect the cable connectors R-Tx and R-Mx with the N-
connector (short-circuited).
Version 1 Connect the flow cell to the evaluation unit as shown in Figure
4-5; make sure that the reference cable (ring line) is connected
to R-Tx and R-Mx.
The reference cable must be as long as the sum of both signal
cables.
