Preparing the Oscilloscope for Use
To connect the oscilloscope probes
To connect the oscilloscope probes
1 Connect the Agilent 10074C 1.5-meter, 10:1 oscilloscope probe to the
analog channel 1 or 2 BNC connector input on the oscilloscope, or
channel 1 through channel 4 on the 54624A.
Maximum input voltage for analog inputs:
CAT I 300 Vrms, 400 Vpk
CAT II 100 Vrms, 400 Vpk
with 10074C 10:1 probe: CAT I 500 Vpk, CAT II 400 Vpk
2 Connect the retractable hook tip on the probe tip to the circuit point of
interest. Be sure to connect the probe ground lead to a ground point on
the circuit.
The probe ground lead is connected to the oscilloscope chassis and the ground
wire in the power cord. If you need to connect the ground lead to a point in the
circuit that cannot be grounded to power ground, consider using a differential
probe.
To compensate your probe
You should compensate you probes to match their characteristics to the
oscilloscope. A poorly compenstated probe can introduce measurement errors.
To compensate a probe, follow these steps:
1 Connect the probe from channel 1 to the
Probe Comp
signal on the lower-
right corner of the front panel.
2 Press Autoscale .
3 Use a nonmetallic tool to adjust the trimmer capacitor on the probe for
the flattest pulse possible.
