1.2.3 Rear Panel Layout
The rear panel contains most of the external connections for the FP35 analyzer.
There are two versions of the FP35 rear panel. The new rear panel (Figure
1.2.3A) was added in February 2007. All analyzers manufactured before this
date (that haven’t had a hardware upgrade) will have the older rear panel pic-
tured in Figure 1.2.3B.
