Figure 4. Daisy-chaining AMPs

Modules in a probe use letter designations to facilitate testing. When an AMP is

attached to the probe, its letter designation depends on (1) how many modules are in

the probe it is attached to and (2) how many AMPs are connected to the probe. Letter

designations are shown in Table 2.
