4. CALIBRATION AND UNCERTAINTY
               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.

               SAMPLE CALCULATION
RADIATED EMISSIONS
Where relevant, the following sample calculation is provided:
Field Strength (dBuV/m) = Measured Voltage (dBuV) + Antenna Factor (dB/m) + Cable
Loss (dB) – Preamp Gain (dB)
36.5 dBuV + 18.7 dB/m + 0.6 dB – 26.9 dB = 28.9 dBuV/m

MAINS CONDUCTED EMISSIONS
Where relevant, the following sample calculation is provided:
Final Voltage (dBuV) = Measured Voltage (dBuV) + Cable Loss (dB) + Limiter Factor (dB) +
LISN Insertion Loss.
36.5 dBuV + 0 dB +10.1 dB+ 0 dB = 46.6 dBuV


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


  PARAMETER                                       UNCERTAINTY

  All emissions, conducted                             3.65 dB
  All emissions, radiated                              5.17 dB
  Temperature                                          2.26°C
  Humidity                                              6.79%
  DC Supply voltages                                    1.70%
  Time                                                  3.39%

Uncertainty figures are valid to a confidence level of 95%.

5. EQUIPMENT UNDER TEST
                 EUT DESCRIPTION
The EUT is a Portable Computing Device that contains 802.11 a/ac/ax/b/g/n 20/40/80/160MHz
2x2 dual band and BT/BLE radios.

Models 1867 and 1868 are electrically and RF equivalent as they use the same motherboard,
radio module and on-board RF components. Both models share a common WiFi and BT power
table. The radio-related firmware and driver versions are the same for the two models. The peak
antenna gains are in the antenna gain section of the report. Antenna port conducted emissions
measurements are done on model 1868 (FCC ID: C3K1868, IC: 3048A-1868) and the data is
leveraged for model 1867 (FCC ID: C3K1867, IC: 3048A-1867). Highest antenna gain across
the two models in each band has been considered while doing the conducted emissions
measurements. Separate radiated & SAR measurements are done on each model.


                 MAXIMUM OUTPUT POWER
Refer to Model 1868 (FCC ID: C3K1868, IC: 3048A-1868) reports R12935938-E5, -E6, -E7, -
E8, -E9, and -E10 for output power.

                  SIMULTANEOUS TRANSMISSION CONFIGURATIONS
The EUT has one intended orientations, X; therefore, all final radiated testing was performed
with the EUT in X orientation.

Simultaneous transmission of the following was investigated:

    •    5GHz and Bluetooth

Per the manufacturer, no other radios transmit simultaneously. The device was found to still be
compliant.

TEST PROCEDURE

The EUT is placed on a non-conducting table 1.5 m above the ground plane for measurements
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 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 and the video
bandwidth is set to 3 MHz for peak measurements and as applicable for average
measurements. Detector used was RMS average detector.

The spectrum below 1 to 18GHz is investigated with the transmitter set to the modes and channels
with the highest output power and PSD.

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.
