Setting Up the Oscilloscope

Digital probe lead set

Digital probe lead set
The 5483xD Infiniium oscilloscopes are the only oscilloscopes that have 16 digital
channels.
The digital clip lead marked clk (clock) is unused. All the other digital clip leads are
used for the digital channels.
The probe lead set has 16 digital channels with a ground lead for each channel.

Digital Probe Lead Set
If a 0.63 mm square pin or a 0.66 diameter round pin is installed on the circuit
under test, the signal and ground leads can be directly connect to these pins.
Otherwise, the IC clips can be used to connect to the circuit.
C A U T I O N
Do not exceed the maximum input voltage rating of ±40 V peak, CAT I.

Probe tip isolation network and equivalent load

The probe tips of the probe lead set contain an isolation network which serves
to minimize the loading effect of the digital channels on the circuit under test.
The isolation network schematic is shown in Figure 1-12.
