1 Introduction

1.1 About this device

The SRM-3006 (Selective Radiation Meter) is a handy-sized frequencyselective measuring system for safety analysis and environmental measurements in high frequency electromagnetic fields in the frequency range from 9 kHz to 6 GHz. Because signals with frequencies of this magnitude are very difficult to sample digitally, the SRM-3006 uses a combination of analog and digital signal processing. It is ideal for measuring absolute and limit values of high-frequency electromagnetic fields such as those due to broadcast radio (AM, FM), TV (analog, DVB-T), BOS (Tetra), mobile telecommunications (GSM, UMTS), radar, and wireless communications (WiMax, WLAN).

In unknown field environments such as those around so-called shared sites, where several providers of mobile telephone services share a common antenna site, the SRM-3006 displays the total field level as well as the contributions made by the individual services, either as absolute values or as a percentage of the permitted limit level. Each service can be resolved down to its individual channels and the contribution made by each channel to the overall field emission measured using the SRM-3006. In the same way, the value can be integrated over the frequency band of the service and the total value displayed, again as an absolute value or in terms of the relevant limit value. The SRM-3006 naturally also includes all the typical functions of a spectrum analyzer and as such can be universally applied. An added bonus is the high measurement speed at small resolution bandwidths (RBW).

The device combines a very wide and varied range of functions within an extremely lightweight and handy design. This makes it possible to use the device particularly under the kind of conditions where good mobility and ruggedness are required.

The complete SRM-3006 measuring system comprises the Basic Unit SRM-3006 and the three axis antenna. Narda Safety Test Solutions also supplies other antennas for the Basic unit, including single axis antennas, covering various applications and frequency ranges. All Narda antennas can be mounted directly on the Basic Unit or connected to it using a special RF cable.

Other commercially available antennas can be connected to the SRM-3006 by cables; these cables can also be of types other than those supplied by Narda.

1 Introduction

1.2 SRM-3006 as a field strength meter

The SRM-3006 is a device for measuring electromagnetic fields in the frequency range 9 kHz to 6 GHz. The main measurement task here is the determination of the field strength.

Several operating modes can be selected. Each operating mode is designed to deliver in-situ immediate, informative results that do not require any further processing or evaluation.

In the simplest case, the complete measuring equipment for determining the field strength consists of the Basic Unit with an antenna mounted directly on it.

Depending on the selected measurement method, it may be useful or even necessary not to mount the antenna directly on the Basic Unit but to place it some distance away and use a cable to connect it.

A 1.5 m long cable is included in all SRM-3006 field strength measuring system sets including antenna that are offered by Narda Safety Test Solutions. A 5 m long cable is available for special applications (see Ordering Information on page 213).

The antenna needs to be exactly positioned and undisturbed for precision measurements. An optionally available tripod with a suitable antenna holder can be added to the measuring equipment for this purpose.

Regardless of the package described, cables and antennas not made by Narda can also be connected to the Basic Unit in order to perform the desired measurements (see Using commercially-available cables and antennas on page 33).

1.2.1 Basic unit

The SRM-3006 is a field meter that has been specially designed for use outdoors and in difficult to reach or uncomfortable measurement locations. The functions of the device have therefore been tailored to ensure ease of handling in practical situations.

Some of the most outstanding features are:

• Handy sized and light in weight despite a wide range of functions

• Ergonomically shaped non-slip grips ensure that the device can be held securely and that all controls can be easily reached during the measurement

• Additional fitting for attaching a wrist strap on the left hand side of the device

• Large, clear LCD with backlight is easy to read under various lighting conditions

• Foil keypad ensures reliable operation under poor conditions or when wearing gloves

• Fast, hassle-free rechargeable battery replacement for longer on-site operating times

1.2.2 Antennas

The standard contents of a SRM-3006 set usually include a three axis antenna. This three axis antenna allows quick and simple isotropic measurements with automatic determination of the three spatial components of the field to be measured. It too has been designed for use outdoors and in hard to reach measurement locations (see Ordering Information on page 213).

Narda Safety Test Solutions also supplies other single axis and three axis antennas for electric and magnetic field measurements which cover further applications and lower frequency ranges.

Every Narda antenna is equipped with a control cable in addition to the RF conductor. This is connected to the Basic Unit by a multi-pin connector, and transfers the antenna parameters (type, serial number, calibration date, list of antenna factors) to the Basic Unit so that the SRM-3006 can recognize and use this data.

1.2.3 Cables

Narda Safety Test Solutions supplies two cables for the connection between the antenna and the Basic Unit. Both cables are suitable for the frequency range between 9 kHz and 6 GHz. The cables are 1.5 m and 5 m long and contain ferrite to reduce the effect of the external field on the measurement results. The cables include a control cable along with the RF conductor. This control cable is connected to the Basic Unit by a multi-pin connector, and transfers the antenna parameters (type, serial number, calibration date, list of attenuation factors) to the Basic Unit so that the SRM-3006 can recognize and use this data. This cable also allows the SRM-3006 to control successive measurement of each of the three axes to determine the isotropic result, or selection of a single axis to determine directional information.

Commercially-available cables can also be used for the connection between the Basic Unit and the antenna. However, three axis antennas cannot be controlled using such cables.

Note: Existing cables with a frequency range from 100 kHz to 3 GHz can

be modified for use at frequencies between 9 kHz and 6 GHz. This modification is free of charge when performed in conjunction with a calibration. You can get further information from one of our Sales Partners in your locality or from our homepage www.narda-sts.de under Service.

1.3.1 Basic unit

The SRM-3006 Basic Unit has the following standard features of a spectrum analyzer:

•The Integration over Frequency Band function in Spectrum Analysis mode can be used to determine the wide band value for an individual channel (Channel Power).

• The service tables in Safety Evaluation mode can be used as channel tables for channel measurements (Channel Power Plus). Clarity is given by displaying the results as a bar graph.

• Noisy signals can be smoothed by adjusting the video bandwidth or by selecting a narrow RBW in Safety Evaluation mode. A compromise with regard to time must be found when smoothing the signals.

• Signals can be observed against time in Spectrum Analysis mode using very narrow and very wide RBWs.

In addition to the above, the SRM-3006 has the following functions (among others):

• The field strength of pulsed signals can be determined rapidly in Level Recorder mode.

• Signals can be analyzed in real time or monitored over a long period of up to 24 hours in Scope mode.

• Spatial averaging and normal averaging provide important information for standard-compliant measurements e.g. for 6-minute intervals.

• Peak Table and Extrapolation functions are provided for evaluating measurements.

• Demodulation enables UMTS mode.

• Certain store events (time, threshold value) can be set to enable recording of specific measurement results.

1.4 PC software

The device can be connected to a PC via the optical interface or the USB port (Mini B type). This allows access to the device functions and measurement results.

• Configuration of the measuring set using the SRM-3006 Tools.

• Remote control commands (see Remote Control on page 175)

3 Connecting Up and Starting to Use the Device

3.4.3 Using commercially-available cables and antennas

Automatic recognition of the cable or antenna type that is connected is not possible if third party products (commercially available cables and antennas) are used instead of Narda components.

This means that when other cables are used the cable loss will not be taken into account, and the results will not be shown in units of field strength or as a percentage of the selected human safety standard limit value if other antennas are used.

Note: The data for the connected cable and antennas must be entered in

the SRM-3006 manually using the PC software if third party products are used (see description below).

Manually entering the data for third party components

The data must first be entered in the PC software, after which they can be uploaded to the SRM-3006.

To enter the data:

1. Enter the data from the calibration report for the third party components

into the PC software (refer to the PC software online help for details).

2. Save the created configuration on the PC.

3. Upload the configuration data to the SRM-3006.

4. Select the cable and / or antenna on the SRM-3006.

3.4.4 Fitting a Narda antenna on a tripod

Special devices are needed for attaching the Narda antennas to a tripod. Two types of antenna holder are available from Narda for this purpose.

Antenna holder for three axis antennas

This antenna holder can be attached to the tripod to allow vertical or horizontal alignment of the antenna. Because the antenna is non-directional (three axis) the alignment should not influence the result in any way. Nevertheless, it is a good idea to align the antenna head roughly in the (presumed) direction of the field source in order to minimize any side effects.

Narda SRM-3006 33

3 Connecting Up and Starting to Use the Device

Assembly

1. Screw the antenna holder vertically or horizontally on to the tripod.

2. Attach the antenna to the holder using the Velcro strips.

3. Connect the antenna and the Basic Unit together using a cable (see

6 Functions Common to More Than One Operating Mode

6.2 Setting the resolution bandwidth (RBW)

Spectrum Analysis • RBW Level Recorder • RBW Scope • RBW

The resolution bandwidth (RBW) determines the characteristics of the spectrum analyzer with regard to its ability to distinguish between signals having the same amplitude. but different frequencies. Only signals having a frequency spacing that is greater than the defined resolution bandwidth can be distinguished from one another.

Background information:

The RBW selected for measuring signals having very close frequency spacing must be correspondingly small. A larger resolution bandwidth can be used for measuring wideband signals.

• The indicated level will be too low if the RBW is too small.

• Individual signals cannot be separated from one another if the RBW is too big.

Example: GSM frequency spacing / signal channel width = 200kHz, RBW = 200 kHz.

To set the resolution bandwidth:

1. Press the RBW softkey.

2. Use the rotary control to select the desired value and press the OK key.

ª The selected value is applied.

6.2.1 Setting the video bandwidth (VBW)

Spectrum Analysis • RBW • VBW Level Recorder • RBW • VBW Scope • RBW • VBW

Noisy signals can be smoothed by selecting a suitable video bandwidth. There are two possible ways to make the setting:

• Off: The SRM-3006 will automatically select the correct VBW value.

• Manual selection

Narda SRM-3006 71

6 Functions Common to More Than One Operating Mode

To set the video bandwidth:

ª The Select Video Bandwidth (VBW) entry box opens.

2. Use the rotary control to select the desired setting and press the OK key.

ª The selected value is applied.

Note: The smaller the VBW, the longer the measurement time (sweep

time).

6.3 Setting the measurement range (Meas. Range)

Safety Evaluation • Meas. Range Spectrum Analysis • Meas. Range Level Recorder • Meas. Range UMTS • Meas. Range Scope • Meas. Range

Background information:

The sensitivity of the system depends on the input attenuator setting. This setting is determined by the Measurement Range (MR) parameter. High measurement sensitivity avoids falsification of the results due to noise generated internally by the device. On the other hand, it is important that the device is not overloaded (saturated). Saturation can also be caused by signals outside the frequency band of the services being measured (shown under Others), e.g. high power radio transmitters when measuring mobile telephone signals.

To set the measurement range:

⇒ Press the Meas. Range softkey.

You can now select the measurement range as follows:

• Manual measurement range selection

• Automatic measurement range search (MR Search)

72 SRM-3006 Narda

6 Functions Common to More Than One Operating Mode

covered by the antenna you are using is made in the background. This takes several seconds. When it is completed, the device sets the measurement range to the optimum value automatically and reverts to normal measurement mode.

Note: Press the ESC key if you want to cancel the process.

MR Search Type

The SRM-3006 provides two types of measurement range search which can be selected using the MR Search Type softkey (toggle function):

• Normal: This type is suitable for all largely static signals.

• Conserv.: This type allows for a higher overload reserve. It is better to set

the measurement range manually if pulsed signals are being measured.

To select the search type:

⇒ Press the MR Search Type softkey.

ª The switch toggles between the two types each time the softkey is

pressed.

6.3.3 Measurement input overload

6.6.1 Measurement using a three axis antenna

Three axis (isotropic) antennas allow you to make simple and quick isotropic measurements by automatically detecting the three spatial components of the field to be measured. Narda Safety Test Solutions offers three antennas for measuring electric or magnetic field strength:

Table 22: Three axis antenna types

Type Frequency range Preferred application

E-field antenna (isotropic), dipole array, passive

H-field antenna (isotropic), coil array, active

It is of course possible to also measure each axis separately using a three axis antenna.

Isotropic measurement

Isotropic measurement mode is selected automatically by default. All three axes are measured one after the other and the isotropic result calculated and displayed by the SRM-3006. The display shows the label Isotropic at lower left.

420 MHz – 6 GHz Fast, non-directional measurements

e.g. at mobile communications and WiMAX frequencies.

27 MHz – 3 GHz Fast, non-directional measurements

e.g. at mobile communications frequencies.

9 kHz – 250 MHz Fast, non-directional near-field

magnetic field measurements on radio/TV transmitters and industrial equipment.

Measuring a single axis

Isotropic measurement mode is selected automatically when a three axis antenna is used.

You can measure each axis separately from the Axis menu for those applications where additional information about the spatial components of the field is required.

The measurement is only useful if the orientation of the sensors relative to the field is known. A tripod with a special antenna holder can be used for Narda antennas (see Fitting a Narda antenna on a tripod on page 33). The positions of the three measurement axes are marked on this special holder.

Narda SRM-3006 85

6 Functions Common to More Than One Operating Mode

Two methods can be selected:

Automatic isotropic

This is the usual setting for isotropic antennas. All three axes are measured automatically and the overall result is calculated.

Manual isotropic

As with a single axis antenna, each of the three axes can be measured separately with this setting. However, it is not necessary to turn the antenna in the direction of each axis. The procedure is as follows: ✓ A three axis antenna is connected directly or via a cable to the

SRM-3006.

1. Select the Manual Isotropic function from the Axis menu.

2. Press the Start X-Axis softkey. When the measurement finishes, press

the Stop X-Axis softkey.

3. Do the same for the Y axis and Z axis.

4. Press the Show Isotropic softkey to display the measurement result.

To make another measurement:

Press the Start X-Axis softkey and proceed as described above.

To change the settings:

1. Press the Change Settings softkey and then change the settings.

2. Press the Back to Axis softkey (highlighted in yellow) to return to

measurement mode.

To finish manual isotropic measurement:

⇒ Press the Axis softkey and select Automatic Isotropic.

6.6.2 Measurement using a single axis antenna

Isotropic measurement using a single axis antenna is much more timeconsuming than using a three axis antenna because each of the three axes has to be measured separately, one after the other.

The SRM-3006 provides support for sequential measurements using single axis antennas and for calculating the isotropic result.

The sections below explain how such measurements can be made.

You can of course use any suitable standard antenna and corresponding cable as well as the items supplied with the instrument.

Single axis measurement

This is the default measurement for single axis antennas. ✓ A single axis or standard antenna is connected directly or by a cable to

the SRM-3006.

⇒ Select the Single Axis function from the Axis menu (default).

Isotropic measurement

The SRM-3006 provides a sequential measurement for making an isotropic measurement using a single axis antenna. The three separate measurements are made one after the other and the overall result is calculated and displayed.

Note: Directional antennas such as log-periodic antennas are basically

unsuitable for such sequential measurements.

To make an isotropic measurement with a single axis antenna:

✓ A single axis or standard antenna is connected directly or by a cable to

the SRM-3006.

1. Select the Manual Isotropic function from the Axis menu.

2. Position the antenna in the direction of the X axis, and press the Start X-Axis softkey. When the measurement has finished, press the Stop X-Axis softkey.

3. Follow the same procedure for the Y axis and the Z axis.

4. Press the Show Isotropic softkey to display the measurement result.

To make another measurement:

Press the Start X-Axis softkey and proceed as described above.
