• The N56XX is mounted and connected to the Honeywell demo board through the 12-pin flex.
• The engine is connected to the host via an 6 foot long, straight USB-A/Micro-B cable (Mouser 538-68784-0003). A clamp-on
ferrite (Fair-Rite p/n 0431173951) was added to USB cable on this configuration.
• The N56XX is operating in USB mode (USBSPD1).
The following pages document the test results.
Note: The charts show the quasi-peak values, which are used to determine pass/fail, while the graphs show maximum hold
values.
Model 1: Corded Unit in TTL-232 Mode (RJ45/RS232)
The illustration below shows a unit similar to the unit tested:
This system passed FCC class B limits at all tested frequencies. The test results are shown in the following charts.
Model 1 - Radiated Emissions Measurements 30-2000 MHz
* All readings are quasi-peak unless stated otherwise.
** Data gathered above 1000 MHz was at a 3m antenna distance with RF absorbing material on the ground plane per
EN55022 A1:2007. No significant amplitudes across the frequency spectrum were measured.
