Connect Probes to the Oscilloscope
1
Connect the oscilloscope probe to an oscilloscope channel BNC connector.
2
Connect the probe's retractable hook tip to the point of interest on the circuit or
device under test. Be sure to connect the probe ground lead to a ground point
on the circuit.
CAUTION
Maximum input voltage at analog inputs
135 Vrms
50
Ω
input: 5 Vrms Input protection is enabled in 50
Ω
mode and the 50
Ω
load will
disconnect if greater than 5 Vrms is detected. However the inputs could still be
damaged, depending on the time constant of the signal. The 50
Ω
input protection
only functions when the oscilloscope is powered on.
