To achieve
Change of internal temperature
∆T = -5°C corresponds to –10 V
Unchanged internal temperature ∆T = 0
corresponds to 0 V
Change of internal temperature
∆T = +5°C corresponds to +10 V
Note that the this is a differential input stage and that both + MODE_HOP_ADJUST
and - MODE_HOP_ADJUST must be connected.
2.5.5 Electrical power and signal connectors
There are two connectors located on the rear side of PICO D, see Figure 2–8. The
top connector (6 pin) is the power connector whereas the 40 pin connector carries
all digital and analog signals. Figure 2–15 show the pin configuration of the two
connectors.
The electrical power connector carries all the required DC power lines. Note in Table
2-10 the increased recommended cable area for the 5 V supply.
Table 2-11 lists the signal interface's pin configuration. The connector is located on
the rear of PICO D, see Figure 2–8.
The type of connectors used is specified in 2.5.5.1 and 2.5.5.1
