2.6 Measurement Uncertainty

All results reported herein relate only to the equipment tested. For the purposes of the measurements

performed by Washington Laboratories, the measurement uncertainty is ±2.3 dB. This has been

calculated for a worst-case situation (radiated emissions measurements performed on an open area test

site).

The following measurement uncertainty calculation is provided:

Total Uncertainty = (A2 + B2 + C2)1/2/(n-1)

Where:

A = Antenna calibration uncertainty, in dB = 2 dB

B = Spectrum Analyzer uncertainty, in dB = 1 dB

C = Site uncertainty, in dB = 4 dB

n = number of factors in uncertainty calculation = 3

Thus, Total Uncertainty = 0.5 (22 + 12 + 42)1/2 = ±2.3 dB.

4 Test Results

4.1 RF Power Output (FCC 25.204, RSS-170 Section 6.2)

FCC 25.204 specifies the limits for Satellite Earth Stations.

In bands shared coequally with terrestrial radio communication services, the equivalent isotropically

radiated power transmitted in any direction towards the horizon by an earth station operating in

frequency bands between 1 and 15 GHz, shall not exceed the following limits:

+40 dBW in any 4 KHz band for θ: 0°

+40+3 θ dBW in any 4 KHz band for θ <0°≤05°

Where, θ is the angle of elevation of the horizon viewed from the center of radiation of the

antenna of the earth station and measured in degrees as positive above the horizontal plane and

negative below it.

IC RSS-170 Section 6.2 and Annex B specify the following requirements:

The output power shall be measured when the transmitter is operating at the manufacturer’s rated

power and modulated with signals representative (i.e. typical) of those encountered in a real system

operation. This measurement shall be carried out before the other tests.

If the power is in bursts, the power shall be averaged over any 100 millisecond interval, or over the

burst interval if the burst is shorter than 100 milliseconds, during which its value is at its maximum.

Record the output power.

4.1.1 Power measurement test procedure – Signal Substitution Method

No direct connection to the antenna is available for making the power measurement as the antenna is

integrated with the unit.

To measure the EIRP the EUT was placed on motorized turntable for radiated testing on a 3-meter

open field test site. The emissions from the EUT were measured continuously at every azimuth by

rotating the turntable. Receiving antennas were mounted on an antenna mast to determine the height of

maximum emissions. The height of the antenna was varied between 1 and 4 meters. Cables were

varied in position to produce maximum emissions. Both the horizontal and vertical field components

of the EUT were measured.

The received level of the detected emission was recorded in the data sheet. The EUT is then replaced

with a transmit antenna and signal generator. Output power of the signal generator was increased until

the same received level was indicated on the spectrum analyzer for the emission under investigation.

Radiated power of the emission was then determined by adding the forward power supplied to the

substitution antenna with the gain of the substitution antenna and comparing the result to the limit.

FCC/IC Test Report

November, 2009

As specified above, the limit is +40 dBW in any 4 kHz band. The analyzer used for testing was

limited to a 3 kHz measurement bandwidth. To adjust to the 4 kHz specification a BW correction of

+1.25 dB was added to the final reading. The following calculations were used for determining the

EIRP level:

Pout (dBW) = SL (dBm) + G (dBi) + -30(dB)

Where: SL is the substitution level in dBm

G is the substitution antenna gain in dBi

-30dB is the conversion factor for dBm to dBW

4.2 Occupied Bandwidth

The occupied bandwidth of the MTXF Mobile Terminal was measured. This measurement was

performed by coupling the output of the EUT via an antenna to the input of a spectrum analyzer. The

20dB occupied bandwidth was measured for the Low, High and Middle channels and the test results

are listed in the following table. Figure 2 thru Figure 4 show plots of the occupied bandwidth.

Table 4: Occupied Bandwidth Results

Frequency

(MHz)

Occupied Bandwidth

(kHz)

Standard

Reference

Low Channel: 1626.505 4.3182 kHz RSS-170

Middle Channel: 1643.5 4.2723 kHz FCC Part 25

High Channel: 1660.5 4.3569 kHz RSS-170

The necessary BW for a 2-ary MSK (Minimum Shift Keying) signal is calculated as follows:

Number of states = 2

Bit Rate R = 3.6 kbps

Factor K’ = 1.18 for a 2-ary MSK signal {NOTE: K’ = (1/Log2(number of States) + 0.18) =

(1/(Ln(2)/Ln(2) + 0.18) = 1 + 0.18 = 1.18} {also note that this is for unfiltered MSK, where any

filtering is sufficiently wide that it has no or little effect on the occupied BW}.

Necessary BW Bn = R X K’ for an MSK signal

Bn = 3.6 kbps X 1.18 = 4.248 kHz

MSK is considered phase modulation (“G”), we utilize a single channel (“1”), and we transmit data

(“D”). This is consistent with Part 2.201 Subpart C-Emissions.

Therefore the emission designator based on FCC part 2.202 is something like 4K25G1D. The actual

emission designator is based on the -26 dB or 99% occupied BW measurement.

4.3.1 Test Procedure

For the FCC Part 25 requirements the unit was set to transmit at 1643MHz and the emissions were

scanned to +/-250% of the authorized bandwidth and compared to the emission mask specified in

FCC Part 25.202(f). The authorized bandwidth used in the calculations for the limit was 7 kHz.

For complying with the RSS-170 emission mask, the unit was first set to transmit at the lowest

authorized frequency of 1626.505MHz. The emission mask of Table B1 column “a” was then entered

into the spreadsheet based on a baud rate of 3600. Discrete measurements of the channel power in a 4

kHz bandwidth were then measured and plotted against the limit curve. The unit was then set to the

highest authorized frequency of 1660.495MHz and the test was repeated.

Spectrum plots of the emissions as measured with a 100Hz RBW were also obtained at the low and

high channel settings.

4.3.2 Test Results

The EUT complies with the emissions mask requirements of FCC Part 25.202(f) and RSS-170 Annex

B. Figure 5 and Figure 6 contain the plots of the emissions mask for FCC Part 25.202(f). Figure 7,

than 100 percent up to and including 250 percent of the authorized bandwidth: 35 dB;

(3) In any 4 kHz band, the center frequency of which is removed from the assigned frequency by more

than 250 percent of the authorized bandwidth: An amount equal to 43 dB plus 10 times the logarithm (to

the base 10) of the transmitter power in watts;

Based on the power measured, the limit for emissions removed from the center frequency by more than

250% of the authorized bandwidth will be:

Limit (dBm) = 34(dBm) – (43 + 10Log(2.51)) = -13dBm

RSS-170:

Spurious and harmonic emissions, excluding the frequency band of ±4 SR about the carrier frequency

(see Section 4.3) shall be attenuated below the transmitter output power TP in accordance with the

following Table from RSS-170 Annex B, when measured with a spectrum analyzer of 4 kHz

resolution bandwidth.

Frequency (MHz) Minimum Attenuation Relative to Tx Power in any 4 kHz

30-1559 83 dB or (65 + 10 Log10TP) dB whichever is less stringent

above 1559 55 dB or (37 + 10 Log10TP) dB whichever is less stringent

The limit for RSS-170 is therefore calculated as:

For 30-1559 MHz: 33dBm – (65+10Log(2W)) = -35dBm

Above 1559MHz: 33dBm – (37+10Log(2W)) = -7dBm

This section covers emissions detected at more than 250% removed from the authorized bandwidth.

4.4.1 Test Procedure

The EUT was placed on motorized turntable for radiated testing on a 3-meter open field test site. The

emissions from the EUT were measured continuously at every azimuth by rotating the turntable.

Receiving antennas were mounted on an antenna mast to determine the height of maximum emissions.

The height of the antenna was varied between 1 and 4 meters. The peripherals were placed on the table

in accordance with ANSI C63.4-2003. Cables were varied in position to produce maximum emissions.

Both the horizontal and vertical field components were measured.

Where emissions were detected, the EIRP levels were determined using the method of signal

substitution. The measurement bandwidth used was set to 3kHz. A 1.3dB correction was added to the

spectrum analyzer signal level for referencing to the specification bandwidth of 4kHz. The actual EIRP

level was calculated as follows.

EIRP (dBm) = Signal generator substitution level (dBm) + Antenna Gain (dBi)

4.6 Spurious Emissions per FCC §25.216

FCC Part 25 limits the emissions from mobile earth stations for the protection of aeronautical radio

navigation-satellite service. The EIRP density of spurious emissions which fall within the frequency

range of 1559M to 1610MHz were measured in accordance with §25.216.

In accordance with §25.216(c) the EIRP density of emissions from mobile earth stations operating

between 1610MHz and 1660.5MHz shall not exceed -70dBW/MHz, averaged over any 2ms active

transmission interval, in the band 1559M – 1605MHz. The EIRP of discrete emissions of less than 700

Hz bandwidth from such stations shall not exceed -80 dBW, averaged over any 2ms active transmission

interval, in the 1559M – 1605MHz band.

In accordance with §25.216(h) mobile earth stations manufactured more than six months after Federal

1626.5-1660.5 MHz band shall suppress the power density of emissions in the 1605-1610 MHz band-

segment to an extent determined by linear interpolation from -70 dBW/MHz at 1605 MHz to -46

dBW/MHz at 1610 MHz, averaged over any 2 millisecond active transmission interval. The e.i.r.p of

discrete emissions of less than 700 Hz bandwidth from such stations shall not exceed a level determined

by linear interpolation from -80 dBW at 1605 MHz to -56 dBW at 1610 MHz, averaged over any 2

millisecond active transmission interval.

In accordance with §25.216(i) the peak e.i.r.p density of carrier-off state emissions from mobile earth

stations manufactured more than six months after Federal Register publication of the rule changes

adopted in FCC 03–283 with assigned uplink frequencies between 1 and 3 GHz shall not exceed -80

dBW/MHz in the 1559– 1610 MHz band averaged over any 2 millisecond active transmission interval.

4.6.1 Test Procedure

The output of the EUT was connected to the input of measurement receiver with a RMS detector and the

capability of performing the measurements as specified in §25.216 (h). The following was used to

calculate the limit and the corrected emissions levels for obtaining the plots shown in Figure 10 through

Figure 22.

For emissions from 1559M – 1605MHz:

Limit = -70dBW/MHz = -40dBm/MHz

For discrete emissions with bandwidths less than 700Hz from 1559M – 1605MHz

Limit = -80dBW = -50dBm

For emissions from 1605M – 1610MHz:

Limit = -70dBW/MHz (-40dBm/MHz) to -46dBW/MHz (-16dBm/MHz)

For discrete emissions with bandwidths less than 700Hz from 1605M – 1610MHz

Limit = -80dBW/MHz (-50dBm/MHz) to -56dBW/MHz (-26dBm/MHz)

Skybitz Inc

MTXM

FCC/IC Test Report

November, 2009

For emissions in the Carrier –Off State from 1559M – 1610MHz

Limit = -80dBW/MHz (-50dBm/MHz)

The receiver emissions levels were adjusted for correction factors as follows:

Emission Level = RXL + ATT+CBL+ANT

Where: RXL = Raw received level

ATT = Attenuator = 20dB

CBL=Cable loss=1.0

ANT= Tri-Band Antenna Gain=2.85dBi (5dBiC)

These correction factors were entered into the receiver as an offset so the obtained plots would display

corrected data for comparison to the limit.

4.7 Frequency Stability: (FCC Part §2.1055)

Frequency as a function of temperature and voltage variation shall be maintained within the FCC-

prescribed tolerances. Per §25.202(d) the frequency tolerance shall be maintained within 0.001% of the

reference frequency.

4.7.1 Test Procedure

The temperature stability was measured with the unit in an environmental chamber used to vary the

temperature of the sample. The sample was held at each temperature step to allow the temperature of the

sample to stabilize.

The frequency stability of the transmitter was examined at the voltage extremes and for the temperature

range of -30°C to +50°C. The carrier frequency was measured while the EUT was in the temperature

chamber. The reference frequency of the EUT was measured at the ambient room temperature with the

frequency counter.

The frequency stabilities can be maintained to a lesser temperature range provided that the transmitter is

automatically inhibited from operating outside the lesser temperature range.

The RF carrier frequency shall not depart from the reference frequency (reference frequency is the

frequency at 20ºC and rated supply voltage) in excess of .001%.

The EUT is powered by a 6 VDC voltage supplied via an external DC power supply.

4.7.2 Test Results

The EUT complies with the temperature stability requirements of FCC §25.202 and RSS-170. Test

results are given in Table 7.
