Connection to DUT
The LAP-F1 comes with two flying lead type of probes included: one low-voltage
probes per channel and four eMMC probes. (Additionally, TTL probes and negative
logic probes are available for purchase.) All of the probe types are active, i.e. they
are not merely pieces of wire but have active components in the probe head that
amplify, filter, isolate and in other ways improve the signal quality. These
characteristics make the probes well-suited for high-speed signal measurements.
Each active probe provides two channels and consists of four cables: two signal
cables and two ground cables that all have Dupont pods on the ends; see Figure 2-6 .
Note that each port on the LAP-F1 carries to signals; the probes connected to port A0
will show as traces A0 and A1 in the software and so on. The two probe signal cables
are numbered; the lowest number will correspond to the lowest numbered channel in
the software. Ex: If a brown probe with numbers 12 and 13 is connected to the 4
th
D-port, then probe lead 12 will be shown on channel D6 in the software and lead 13
on channel D7. See the port names on Figure 2-5.
