The patented EMC-scanner measures the emission from PCB’s,  components, cables and products.

There are high demands for electro­magnetic compatibility (EMC) of electronic products. The demands are stated in different set of rules, for example: VCCI, ANSI, CISPR, FCC and VDE. These demands are specified for products or systems and not for com­ponents or elements. The fact that there is no easy way to find the exact location of a radiating source is a problem for designers today.

Detectus AB has developed several measuring systems with which designers can measure the intensity and the location of a radiation source at a component level. The results of such a measurement can be shown as two or three dimensional coloured maps. The measurements can easily be repeated creating objective, comparative measurement results. Please contact us at info@detectus.se for more information.

IMMUNITY SCANNING

During measurement the EMC-scanner moves the antenna to predetermined measuring positions above the test object. In each measuring position the signal generator sweeps in frequency and amplitude while the EDD measures for test object failure. If your signal generator allows it, you can also use different modulations such as FM, AM and Pulse.

The measuring procedure

The patented Immunity software option allows you to use a Detectus EMC-Scanner system, a signal generator with a small antenna and an Error Detection Device (EDD) to measure the immunity against radiated electro magnetic interference of components, cables, PCB’s and products. The measurements are easily interpreted and can be repeated for objective comparison.

Visual Immunity test

The Error Detection Device, or EDD for short, can be any type of GPIB or VISA controllable instrument that measures a value from the test object to determine when the test object fails. The EDD can for example be a voltmeter or a protocol tester.

 

 

Use any Error detection device

From an Immunity Scan measurement the DSS software can produce two or three dimensional colour maps showing sensitive hot spots at any frequency. Also printable reports can be generated. The reports include the colour map, graphs and all the measurement settings.

Increase quality by comparing products under production through measurement of a properly functioning master.

The system’s 16 bits digital resolution, the software’s optimization method as well as the ability to adjust offset and emission factors result in high resolution measurements. The system gives you the possibility to localize small heat sources such as surface mounted components

Precision

Why should you, as a designer, be without the ability to measure the temperature of your products? Is this due to cost or inaccessibility? In that case, the solution is the heat scanner from Detectus AB. Heat scanner is a high-resolution measuring system for anyone wishing to measure temperature accurately and inexpensively. The measurements are presented graphically as either two or three-dimensional images.

IC MEASUREMENT

IC measurement option

IC option

The IC-option includes:

The IC-option allows you to:

The new high resolution real time inspection camera shows a microscopic view of the probe tip and the test object. The resolution of the image is better than 10μm/pixel. The inspection camera will allow you to define your measuring path very accurately and to examine measurement result with accuracy and confidence.

  • A real time inspection camera with 10 μm resolution and digital zoom.
  • Mounting for high resolution near field probes.
  • LED lighting.
  • Software features for zoom, pan and screen shot.

 

  • Define your measuring path very accurately.
  • Examine measurement result with accuracy and confidence.
  • Use the special high resolution near field probes to take full advantage of the HRE scanners 25 µm resolution.
  • Zoom in and see details beond the capability of the naked eye.

Probe options

Features products

To complete the IC-option there are three high resolution probes to choose from: electric, magnetic with horizontal loop and magnetic with vertical loop. The probes has a built in preamplifier and are equipped with special mounting details to fit the IC-option.

 

There are several other ICR type probes in different sizes and frequency ranges available.

4-AXIS ROTATION

Automatic rotation around probe axis

The HRE4x-series of Scanners are exactly like the HRExseries with the addition of a device for automatic rotation around the probe axis. During measurement the Scanner will rotate the probe and find the “worst case” angle and then store the amplitude. This procedure is performed in every measuring position. The probe can be setup to rotate in steps down to one degree. The ability to rotate the probe means that you no longer have to worry about missing sources of radiation due to the fact that your probe has different sensitivity in different angles. It will also enable you to more easily follow cables, traces on PCBs and even bonding wires in a chip.

STRIP LINE CALIBRATION

Enables you to accurately measure the field strength of the magnetic near field and to compare measurements made with different probes and setups.

The strip line calibration feature uses a well defined strip line board and a spectrum analyzer with built in tracking generator to automatically generate a set of probe correction factors in Detectus Scanner Software. The correction factors will compensate for imperfections in the probe, cables, connectors and pre-amp.

 

The Strip line

The strip line calibration option includes:

  • The strip line board.
  • A 50 ohm termination.
  • A software key that enables the calibration wizard.

 

 

The calibration procedure only takes a few minutes and is very easy to perform. Just follow the step-by-step wizard. The wizard includes detailed instructions on how to connect everything and setup the calibration measurement. Calibration can be made on any magnetic near field probe and covers a frequency range from 10 MHz to 6 GHz.
