4. CALIBRATION AND UNCERTAINTY

4.1. MEASURING INSTRUMENT CALIBRATION
The measuring equipment utilized to perform the tests documented in this report has been
calibrated in accordance with the manufacturer's recommendations, and is traceable to
recognized national standards.

4.2. SAMPLE CALCULATION
Where relevant, the following sample calculation is provided:

Cable Loss (dB) – Preamp Gain (dB)
36.5 dBuV + 18.7 dB/m + 0.6 dB – 26.9 dB = 28.9 dBuV/m

4.3. MEASUREMENT UNCERTAINTY
Where relevant, the following measurement uncertainty levels have been estimated for tests
performed on the apparatus:

PARAMETER UNCERTAINTY
Worst Case Conducted Disturbance,
3.84 dB
9KHz to 0.15 MHz
Worst Case Conducted Disturbance,

4.32 dB
1000 to 18000 MHz
Worst Case Radiated Disturbance,
4.45 dB
18000 to 26000 MHz

5. EQUIPMENT UNDER TEST

5.1. DESCRIPTION OF EUT
The EUT is a Bicycle Seatpost with AIREA, BLE and ANT+ Radios.

5.2. MAXIMUM OUTPUT FUNDAMENTAL FIELD STRENGTH
The transmitter has a maximum peak fundamental field strength as follows:

Frequency Range Mode Peak E-field Strength Avg E-field Strength Distance
(MHz) (dBuV/m) (dBuV/m) (m)
2405 - 2475 ANT + 92.54 92.01 3.00

5.3. DESCRIPTION OF AVAILABLE ANTENNAS

The radio utilizes a chip antenna, with a maximum gain of -2 dBi.

5.4. SOFTWARE AND FIRMWARE
The EUT firmware installed during testing was A-1.0.
The test utility software used during testing was Lightblue v2.6.4

5.5. WORST-CASE CONFIGURATION AND MODE
Radiated emissions below 1GHz and above 18GHz were performed with the EUT set to
transmit at the channel with highest output power as worst-case scenario.

Band edge and radiated emissions between 1GHz and 18GHz were performed with the EUT set
to transmit at the highest power on low, middle and high channels.

The fundamental of the EUT was investigated in three orthogonal orientations X, Y, Z, it was
determined that Y orientation was worst-case orientation; therefore, all final radiated testing was
performed with the EUT in Y orientation.

TEST PROCEDURE

The EUT is placed on a non-conducting table 80 cm above the ground plane for measurement
below 1GHz; 1.5 m above the ground plane for measurement above 1GHz. The antenna to EUT
distance is 3 meters. The EUT is configured in accordance with ANSI C63.10. The EUT is set to
transmit in a continuous mode.

For measurements below 1 GHz the resolution bandwidth is set to 100 kHz for peak detection
measurements or 120 kHz for quasi-peak detection measurements. Peak detection is used
unless otherwise noted as quasi-peak.

For pre-scans above 1 GHz the resolution bandwidth is set to 1 MHz; the video bandwidth is set
to 30 KHz for peak measurements.

For final measurements above 1 GHz the resolution bandwidth is set to 1 MHz; the video
bandwidth is set to 3 MHz for peak measurements and as applicable for average
measurements.

The spectrum from 1 GHz to 18 GHz is investigated with the transmitter set to the lowest,
middle, and highest channels in each applicable band. Below 1GHz and above 18GHz
emissions, the channel with the highest output power was tested.

The frequency range of interest is monitored at a fixed antenna height and EUT azimuth. The
EUT is rotated through 360 degrees to maximize emissions received. The antenna is scanned
from 1 to 4 meters above the ground plane to further maximize the emission. Measurements are
made with the antenna polarized in both the vertical and the horizontal positions.
