Preparation before Measurement
1.
Have the probe and an oscilloscope with probe interface ready.
2.
Insert the probe interface unit completely into the oscilloscope
input, and confirm that the BNC connector and the interface spring
pins are securely fastened. The latch click will be heard when the
connectors lock into place.
3.
When the probe is connected to an oscilloscope with probe
interface, the probe interface is automatically detected, and the
probe’s attenuation ratio and the input coupling of the oscilloscope
are set automatically
4.
Attach any of the provided attachments or self-made attachments
to the signal input terminals of the probe head.
Note
Accurate measurements may not be possible near objects with strong
electromagnetic fields such as transformers, large current circuits, or wireless
equipment.
Handling the Attachments
Select an attachment suitable for the device under measurement
according to the following table, and connect it to the signal input
terminals of the probe head illustrated below. See also “Example of
Connecting the Attachments” illustrated below. See the Appendix 1 for
frequency characteristics of each attachment.
Pair leads
5-cm and 10-cm pair leads can be connected directly to the device
under measurement, such as a pin header, or be used in combination
with micro clips. The pair leads contain
the
following damping resistors,
which take the connection and combination into consideration.
The
10-cm pair leads are especially suitable for measuring relatively low-
frequency signals.
• 5-cm pair leads
100 Ω, 1/4 W, 1 %
• 10-cm pair leads
150 Ω, 1/4 W, 1 %.
The pair leads can be connected to a 0.64-mm square pin
or a Φ0.65-
mm pin.
