To install the ferrites
Ferrites are included in the HP 16555A/D accessory pouch for each logic analyzer cable (two
pods). When properly installed, the ferrites reduce RFI emissions from the logic analyzer
module.
In order to ensure compliance of the HP 16555A/D analyzer module to the CISPR 11 Class A
radio frequency interference (RFI) limits, you must install the ferrite to absorb radio
frequency energy. Adding or removing the ferrite will not affect the normal operation of the
analyzer.
1
Place the ferrite halves on the logic analyzer cable like a clamshell around the whole
cable. The ferrite should be no more than 15 cm (about 6 in) from the rear panel of
the logic analyzer.
2
Insert the clamps onto the ends of the ferrites. The locking tab should fit cleanly in
the ferrite grooves. When properly installed, the ferrite should appear on the logic
analyzer cable as shown below on the right.
