Handling and Safety Instructions

Introduction

1.1 General information about this guide
This guide is valid for the 5G FR2 antennas (3591/01 and 3591/02) and their associated accessories. In the following, the 5G low-noise block downconverter are referred to  as the LNB antenna.

• These instructions offer a quick introduction on how to install the product. For more information, please refer to the SRM-3006 operating manual (3006/98.21).
• Also read the Narda General safety instructions (3300/98.10) carefully for information about how to operate the LNB antenna in a safe way together with the unit it is connected to.
• Keep this guide, the Narda General safety instructions (3300/98.10) and the guide of the basic unit the LNB antenna is connected to, so that they are always available to all users.
• Only ever pass the LNB antenna and basic unit (SRM-3006) on to third parties together with the guides mentioned above.

1.2 Product description
Two LNB antenna models are available: a directional antenna with high sensitivity and an omnidirectional antenna. Both antennas include a downconverter that converts the millimeter wave band from 24.25 GHz to 29.5 GHz into the SRM-3006’s receive band. This means that the RF cable between antenna and basic unit only transmits  requencies up to a maximum of 6 GHz, which greatly reduces the cable loss compared to a 20 GHz cable. In addition, due to the fact that the downconverter is integrated in the antenna, it can be used with all SRM-3006 devices without any hardware modifications.
Only a firmware update is required, which easily can be done by the user. The LNB antennas have a built-in battery, which is independent from the basic unit. Thus, the runtime of the SRM-3006 is not affected by the operation of the antennas.
The battery can be charged via an USB-C socket. Connected to a USB power bank, long-term measurements can also be performed.
Narda recommends to generally connect the antennas to the SRM-3006 using an RF cable.

3591/01 LNB Antenna, 24.25 to 29.5 GHz, dir.
When measuring inside buildings, the field strengths are often very low. For example, a modern, coated glass window can attenuate a signal at 24 GHz by about 30 dB. To be able to detect a field strength of such a low level, a high gain antenna is needed. In turn high gain antennas have a high directivity due to their design. The LNB antenna 3591/01 is a directive antenna with high gain.
In addition, the directional characteristic can be used to detect the field strength of geographically separated base stations. Depending on how the antenna is held, it receives primarily horizontally or vertically polarized RF signals. A label on the antenna indicates the polarization.
3591/02 LNB Antenna, 24.25 to 29.5 GHz, omn.
For EMF measurements, national and international standard recommendations require EMF measurements to be performed isotropically. However, isotropic antennas are
not available for the FR2 frequency range.
The LNB antenna 3591/02 offers an omnidirectional characteristic that roughly corresponds to the shape of a donut, which is as close as you get to an isotropic characteristic in the FR2 frequency range. Ideal results with the 3591/02 antenna are therefore obtained in an X-Y spatial plane. To cover all three spatial axes for isotropic measurements, the antenna must be moved accordingly during the measurement.
NOTE:
To move the antenna easily, the antenna must be connected to the basic unit via an extension cable.

• The omnidirectional LNB antenna has its minimum in axial direction (donut shape antenna pattern). Therefore, do not align the antenna axially with the RF source during the measurement, as this will create significantly underestimated results!

• The LNB antenna may only be operated by appropriately qualified and trained personnel.

Not intended use
The LNB antenna products listed in the chapter General information about this guide on page 31 in combination with a basic unit (SRM-3006) are no warning devices that actively warn of the existence of dangerous fields by means of optical or acoustic signals.

• Always consider the LNB antenna and basic unit (SRM-3006) as a measuring device, never as a warning device.
• Only approach unknown field sources with careful observation of the current measured and displayed value.
• In case of doubt, also use a wideband warning device such as RadMan or Nardalert from Narda Safety Test Solutions.

2.2 Storage and transport
Storage of the device at too high temperatures or in the sun may cause overheating and consequential damages.

• Do not expose the product or battery to high temperatures, high humidity or direct sunlight during operation, transportation and storage.
• Do not leave the product in a car with closed windows, especially when it is hot outside.
• Do not expose the product to dust, smoke or steam
• Use and store the LNB antenna and its accessories within the guaranteed operating range (for details, see Recovery after shipping and storage on page 39).

2.3 Handling lithium-ion batteries
This product includes a rechargeable lithium-ion battery.

• Before using this product, read and carefully follow all instructions for handling and charging the battery in the Safety Instructions (3300/98.10) delivered with the product.
• Dispose of used batteries in accordance with local laws or regulations.

Battery life
The life of the rechargeable battery is limited. Over time, the performance of the battery slowly degrades. Battery life also depends on storage method, usage, environment, and other factors.
Charging should be performed in an environment with a temperature between 0 °C and 30 °C. In environments with deviating conditions, the charging process may be impaired under certain circumstances.
When not in use
If the LNB antenna is not used for a long period of time, it should be sufficiently charged before storage and fully charged at least once every 6 months to ensure  erformance.
2.4 Commissioning
Commissioning of damaged equipment or accessories may cause consequential damage.

• Inspect the LNB antenna and all accessories for transport damage after unpacking.

• Do not put a damaged device into operation, but rather contact your responsible sales partner in case of damage.
  Both the LNB antenna and the basic unit, when stored or transported at low temperatures, may develop condensation when placed in a warm room. Operating the devices in this condition can damage them.

• To avoid damages, wait until no more condensation is visible on the surface of the LNB antenna and the basic unit (SRM-3006).

2.5 Installation
Mounting the LNB antenna on a tripod

• Make sure that the tripod is mounted in such a way that it is stable so that it does not tip over easily.
• The mounting should be resistant against external influences (for example, wind or shocks to the tripod).

NOTE:
Please note that for most applications the LNB antenna must be moved/swept during the measurement to cover all spatial axes.
Usage/Installation in extreme conditions
Usage/installation in extreme weather conditions may cause personal injury and/or damage to the LNB antenna.

• Do not use the LNB antenna during lightning storms. This also applies to installations on a tripod.
• Extra caution must be taken in extreme weather conditions (for example storm, hail).
• If ice is deposited on the LNB antenna, the measurement results may not be as accurate as under standard conditions.
• If there is a risk of corrosion to the connectors (antenna/cable) due to environmental influences (salty air, airborne chemicals, and so forth), take suitable measures to protect and seal the unit and the connectors.

2.6 Operation
Electrical voltages are present inside the unit.

• Do not bring the LNB antenna into contact with live parts.
• Do not open the LNB antenna. Opening the LNB antenna invalidates any warranty claim.
• Only use accessories intended for the LNB antenna.

Operation of a damaged LNB antenna or accessories may result in significant measurement errors and consequential damages.

• Check the LNB antenna and accessories regularly for damage. Cracks or fractures in the housing indicate possible interior damage and, thus, possible incorrect measurement results.
• In the event of damage or suspected malfunction, take the LNB antenna out of operation and contact your responsible sales partner. Addresses can be found on the Internet under www.narda-sts.com.

2.7 Electromagnetic fields
Strong electromagnetic fields
Very strong electromagnetic fields are generated in the vicinity of certain radiation sources, which can lead to injuries or death in the case of endangered persons.

• Observe safety barriers and markings.
• People with active implants in particular must avoid dangerous areas.

Extreme field strengths can damage the sensor.

• If necessary, immediately remove the device from the environment of the field source.

Unsuitable frequency range
By selecting an unsuitable frequency range, dangerous fields can be overlooked. Staying within such fields may cause injury or death to persons at risk.

• Select the largest selectable or appropriate frequency range.
• Only approach unknown field sources with careful observation of the current measured and displayed value.
• In case of doubt, also use a wideband-measurement warning device such as RadMan or Nardalert from Narda Safety Test Solutions.

Measurements with the LNB antenna
Metallic stickers in the sensor area of the LNB antenna can lead to measurement errors, in particular to an underestimation of the electromagnetic field strength and misleading results.

• Do not attach metallic materials (for example, labels) to the radome of the LNB antenna.

Use of a defective LNB antenna
Through a defective LNB antenna, it is possible that existing high radiation values cannot be detected and bearing results are misleading.

• Make sure that you know the frequency, field strength and polarization to be expected before starting an RF radiation measurement.

2.8 Cleaning
Penetrating liquids
Liquids that penetrate inside the device, could damage or destroy it.

• Make sure that no liquids penetrate inside the LNB antenna.

Solvent
Solvents can damage the surfaces of the device.

• Do not use any solvents to clean the LNB antenna.

2.9 Calibration, repair and modification
The LNB antenna is designed for low maintenance. Regular calibration is necessary to ensure the faultless measurements.
Unauthorized or improper repairs or modifications
Unauthorized or improper repairs or modifications can impair the accuracy and function of the device.

• Repairs should only be carried out by approved Narda Service Centers. Otherwise, any warranty claims shall lapse.
• Modifications to the LNB antenna are not permitted. Modifications void any warranty claims.
• Calibration should only be carried out by suitable (accredited) laboratories. Find out in advance whether the calibration is suitable for your measuring task.

Setup and installation

5.1 Power supply
The standard power supply is provided via the integrated battery. Therefore the LNB antenna does not affect the runtime of the SRM-3006 basic unit. The battery of the LNB antenna is pre-charged upon delivery and must be fully charged before first use. The LNB antenna can be connected to a power supply via a USB-C cable for operation and for charging the internal battery. Connected to a USB power bank, long-term measurements can also be performed.
NOTE:
Please make sure that the AC power cord is equipped with a ferrite filter positioned next to the LNB antenna power supply. This is important to ensure the power supply is in line with the EMF standards mentioned in the datasheet.
Charging the batteries:
Mains voltage must correspond to the operating voltage of the charging/ power supply device.

1. Connect the charger/power supply device to the charging USB socket of the LNB antenna.

2. Connect the charger/power supply to the mains.
   Charging starts immediately.
   The Battery status LED lights red during the charging cycle.
   When the battery is charged, the Battery status LED lights green.

3. Remove charger/power supply device.

Battery error
A red flashing Battery status LED signals a battery error.
In this case unplug the antenna from the SRM-3006 basic unit and contact your Narda representative.
5.2 RF cable connection
When measuring, the LNB antenna should be connected to the basic unit via an RF cable. This is to reduce the risk of damaging the connector on the basic unit due to the weight of the LNB antenna. It also makes it easier to sweep the volume in question when the LNB antenna alone is moved in space compared to moving both the basic unit and the antenna, which in the long run will be very tiresome.
NOTE: Make sure that the cable does not turn while screwing. Otherwise, the electrical properties of the high-quality coaxial cablecould be impaired by torsional forces.
Connecting the RF cable to the basic unit (SRM-3006):

• See chapter 3.4.2 in the SRM-3006 operating manual (3006/98.21) for more detailed information.

Connecting the RF cable to the LNB antenna:
