Probe-BNC(m)
Adapter
This is used to change the probe input to BNC(m) connector. To change the probe input
to the BNC 50
Ω
system, insert the probe into this adapter and connect a 50
Ω
feed-through termination.
10:1 Divider
This is used to divide the probe input level by a factor of 10. Before using this divider, the
divider adjustment should be performed (refer to
“Preparation for Use” on page 20
).
100:1 Divider
This is used to divide the probe input level by a factor of 100. Before using this divider,
the divider adjustment should be performed (refer to
“Preparation for Use” on page 20
Slip-on Spanner
Ground Tip
This is used to ground the probe. Put this ground tip on the probe to probe a test point
and a ground point simultaneously.
Ground Clip
This is used to ground the probe. When a test point and a ground point cannot be probed
simultaneously, put this ground clip on the probe and connect the alligator clip of the
ground clip to a ground point.
Select the grounding devices (slip-on spanner ground tip and ground clip)
for as short a ground path as possible. The effects of improper grounding
become greater as the frequency increases. For optimum measurements in
a factory environment, design your circuits with ground plane
feedthroughs next to each test point.
