Using the scanner requires specialists or specially trained personnel. These users also need sound knowledge of at least one of the languages in which the user interface and the product documentation are available.

If any part of the product is damaged or broken, stop using the product. Never open the casing of the scanner or its components. Only service personnel authorized by Rohde & Schwarz are allowed to repair the product.

Lifting, carrying and installing the R&S QPS

The R&S QPS is heavy and can cause physical injuries when it falls or tips over.

Setup and installation must be done by trained staff. Make sure to install the R&S QPS exactly as described in the installation manual. During the installation, make sure that the installation site is only accessible by people working on the installation.

Because of its weight, at least two strong people are required to move or install the scanner. Lifting heavy items can cause structural and muscular injuries. You must use the specially designed installation tool if you have to move or lift the scanner panels (R&S QPS-Z800, order no. 1333.5900.02). You must also use the installation tool to install the scanner on the platform.

Using the installation tool can pinch your fingers, especially when you attach it to the R&S QPS and when you use the levers.

Loose ball-lock pins can cause the panels to fall over during transportation. Make sure that the ball-lock pin is seated correctly whenever you use one.

If you have to move the pallet the R&S QPS is delivered on, always use a forklift.

During transport, installation or repair, wear appropriate protective clothing that complies with your local rules and regulations. If you are unsure of which equipment to use, ask your safety inspector.

We recommend to wear:

  • Safety shoes with toe cap and ESD protection.
  • Protective gloves

ESD protected shoes and gloves also protect the hardware from being damaged.

Installing cables

A R&S QPS installation consisting of the scanner, operator touchscreen and monitors requires cable connections (power cables, LAN cables etc.). Make sure to secure all cables on the floor and cover them up.

Loose cables are a tripping hazard. Tripping on cables can cause physical injuries.

Properly covered cables also minimize the risk of cable damage.

Choosing the operating site

Use the R&S QPS only indoors. The R&S QPS is not waterproof and water that enters can electrically connect the casing with live parts. This can lead to electric shock, serious personal injury or death if you touch the casing.

For more information on environmental operating conditions, such as ambient temperature, and humidity, see the data sheet.

Supplying the R&S QPS with power

You can connect the R&S QPS to the power distribution system normally used to supply energy-consuming equipment, such as household appliances and similar loads.Electrically powered products have risks, such as electric shock, fire, personal injury or even death.

Take the following measures for your safety:

  • Only use the power cable delivered with the R&S QPS. It complies with country specific safety requirements. Only insert the plug into an approved grounded outlet.
  • For components that need an external AC adapter, only use the one that is delivered with the components.
  • Only use intact cables and route them carefully so that they cannot be damaged. Check the power cables regularly to ensure that they are undamaged.
  • If the voltage or frequency is higher than 230 V or 50 Hz, the leakage current of the R&S QPS can be above the limits. In that case, a protective ground connection must be established for each panel before connecting them to the mains supply.
  • Only connect the R&S QPS to supply networks with a fuse protection of maximum 20 A.
  • Ensure that you can disconnect the product from the mains supply at any time. Pull the power plug to disconnect the product. The power plug must be easily accessible.

Calibrating the R&S QPS

The calibration cylinder is heavy and can cause physical injury.

Install the calibration cylinder exactly as described in the installation manual.

At least two people are required to carry or lift the calibration cylinder.

Installing the calibration cylinder requires a ladder. At least two people are therefore required to install the calibration cylinder – one person must secure the cylinder and ladder while the second person assembles the calibration setup.

Key Features

The R&S QPS Quick Personnel Security Scanner is a system that allows the detection of hidden metallic and non-metallic objects that a person might carry in or underneath their clothing.

Possible threats like weapons or explosives can be detected and measures taken against them.

The objects are recognized by an evaluation of the reflected (backscattered) microwave signal. The microwaves are of very low intensity. The signal level is several orders of magnitude below the signal level of mobile phones. Therefore, the system presents no health hazards for the scanned persons.

A person is scanned, front and back. The data is analyzed and evaluated by an automatic detection software (algorithm).

After the evaluation, the scanned person either is cleared, or has to undergo further investigation in the form of a manual screening. The manual screening can be performed by the screener or by additional inspectors in a separate resolution station.

In case of an inadequate scan, the scan can be repeated or followed by manual screening.

EMI Suppression

Electromagnetic interference (EMI) may affect the measurement results.

To suppress generated electromagnetic interference (EMI):

  • Use suitable shielded cables of high quality. For example, use double-shielded LAN cables.
  • Always terminate open cable ends.
  • Note the EMC classification in the data sheet.

System Components

The system consists of various parts.

  • Two panels that contain the measuring electronics. The first panel (= primary panel) scans the front of a person. The second panel (= secondary panel) scans the back of a person. The primary panel controls the secondary panel, therefore both panels must be connected to each other.The primary panel shows the silhouette of a person. Otherwise both panels are the same.
  • A floorplate that provides a stable and even surface for the scanner.
  • A touchscreen monitor to control the scanner. The touchscreen monitor is connected to the primary panel.

The images show the components of HW 3.50. The components of HW 3.30 are the same, except for the connectors which are at a different location on the panel.

The R&S LPS is the same as a R&S QPS HW 3.50 but with 30 antenna clusters instead of 32 in each panel.

Establishing a ground connection

  1. WARNING! Risk of electric shock. If the voltage or frequency are greater than 230 V or 50 Hz, the leakage current of the R&S QPS can be above the limits and can cause personal injuries from an electric shock.In that case, a protective ground connection must be established for each panel before connecting them to the mains supply.
    • 200 V to 230 V AC and 50 HzNo additional protective ground needed.
    • 230 V to 240 V AC or a frequency greater than 50 HzAdditional protective ground needed.Exception: The following two 60 Hz AC distribution systems are tested and work without an additional ground.3-Phase WyeSingle phase, 2 wireFor the separate protective ground, you need a green/yellow ground wire with a cross section of at least 4 mm2 in addition to the main protective earthing terminal.The ground wire must be connected permanently to the ground terminal on the side of each R&S QPS panel and earth.The ground terminal is located on the power supply. Connect the terminal to the protective grounding system of the building or room where the scanner is installed.Figure 6-2: Ground terminal
  2. Make sure that the power supply is adequately protected against overcurrent. Otherwise the fuse can blow.We recommend that you use a power cable that is rated for a 16 A (included in the delivery) and connect each panel to a separately protected power circuit (at least 10 A).If you cannot connect the panels to separate power circuits, make sure that the system is protected:
    • By a fuse with at least 20 A in 200 V networks.
    • By a fuse with at least 16 A in 230 V networks.
  3. If the voltage drops to 70 % for 500 ms, a reboot occurs.
