Ferrites
Ferrites are included in the 1664A accessory pouch for the logic analyzer cable. When
properly installed, the ferrites reduce RFI emissions from the logic analyzer.
In order to ensure compliance of the 1664A Logic Analyzer to the CISPR11 Class A radio
frequency interference (RFI) limits, you must install the ferrite to absorb radio frequency
energy.
Note: Adding or removing the ferrite will not affect the normal operation of the analyzer.
Ferrite Installation Instructions
Use the following steps to install the ferrite on the logic analyzer cable.
1
Place the ferrite halves and spacer on the logic analyzer cable like a clamshell
around the whole cable. The ferrite should be 10 cm (about 4 in) from the the end of
the cable shell as shown.
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.
