Using Probe Heads
6. N2851A QuickTip Probe Head
The N2851A QuickTip probe head is used with an
N2849A QuickTip and together they provide the
following advantages:
• Easy-to-make secure magnetic mechanical connection between the probe
head and QuickTip. Three magnets in the head connect the two sides of a
differential signal and a ground. No latch lever is used!

• Extreme temperature environments such as temperature chambers.
Permanently solder any number of QuickTips to your DUT as shown in Figure 35
on page 61. Because the probe head is magnetically connected (instead of
mechanically connected) to the QuickTip, you can effortlessly connect and
disconnect to each QuickTip. For best performance, position the QuickTip
vertically on the DUT. The N2849A QuickTip has two signal leads and two ground
leads. The ground leads have minimal effect on your differential measurements.
However, if you are making only differential measurements you can optionally cut
off the ground leads or fold them out of the way. Be aware that without the ground
leads, the mechanical stability of the QuickTip will be reduced and you will need to
stabilize the probe head.
