Measurement scenarios can be

deﬁ ned by the user to ﬁ t speciﬁ c

requirements

➊ INSITE Free SW is a ﬂ exible tool that can be

conﬁ gured by the user to perform measurements

and generate reports according to speciﬁ c measu-

rement protocols, in particular those recommended

by ECC.

➋ In addition, for the French market, INSITE Free/

ANFR SW follows the protocol v2.1 of the French

National Agency of Frequencies (ANFR) step by step.

STEP 1: Choose hardware conﬁ guration.

In this ﬁ rst phase, the user programs the measurement

session according to his own hardware conﬁ guration:

spectrum analyzer, GPS, probe, cable, UMTS scanner

and switch. For this purpose, the probe, cable and switch

calibration ﬁ les are selected and loaded.

INSITE Free works with all of the most frequently used

spectrum analyzers.

STEP 2: Deﬁ ne measurement scenario

Once the hardware has been conﬁ gured, the user can

program the measurement scenarios:

• Choose frequency bands to be measured from

a list or create user-deﬁ ned bands.

• Deﬁ ne the channels or speciﬁ c carriers.

• Deﬁ ne channel width.

• Choose attenuation mode.

• Choose analysis mode (peaks, TDMA or W-CDMA).

• Choose automatic or manual deﬁ nition of RBW/VBW.

STEP 3: Perform measurement analysis.

The data collected for each band is presented on the main

window of the software. Measurements corresponding

to each of the three axes can be displayed in order to

check the polarisation of the electric ﬁ eld.

Depending on the characteristics of the spectrum analyzer,

the user can repeat the following analysis modes:

• CW Analysis: selection of peaks according

to predeﬁ ned threshold.

• TDMA analysis: extrapolation of BCCH value.

• W-CDMA analysis: UMTS decoding (measurement

and extrapolation of the CPICH value).

The user can re-launch measurements using speciﬁ c

detection modes (positive peak, negative peak, sample…)

and measurement modes (Max. hold, Min. hold, and

average) available with the spectrum analyzer.

STEP 4: Visualize results.

The results can be visualized with the following functions:

• Full scan or per frequency band.

• Zoom in with peak identiﬁ cation threshold.

• 3 types of scale for a better high and low

band visualization.

• Quick view of element’s properties.

Sessions are saved in XML and results can be exported

into Excel.

The results can be compared to the reference levels

given by speciﬁ c guidelines. Two guidelines are available

by default:

• ICNIRP

• Safety Code 6

(Other reference levels can be added upon request).
