Visual Noise Detection

The patented EMC-scanner measures the emission from PCB’s,  components, cables and products. The system consists of an  X-Y-Z robot, a spectrum analyzer with near field probe and a standard PC with custom software and a GPIB card or similar for communicating with the spectrum analyzer. During measurement the near field probe is moved by the robot to a grid of measuring points above the test object. At each measuring point the location of the probe and the value of the emission intensity is stored in the computer. After the measurement the results can be documented in different types of reports.

Calibrate to beacon

The scanner tables of the HRE-series scanners are equipped with beacons for automatic and accurate probe calibration.

Calibrating to the electric center point of probe helps you reproduce high quality measurement results every time.

Objective comparative measurement with different de-coupling

Objective comparative measurements

One of the most useful features of the EMC Scanner system is that it enables you to make truly objective comparative measurements.

 

To the left, you can see an example of comparative measurements. The six measurements show the same test object and the same frequency. The difference is the value of the de-coupling capacitor of one IC.

 

MultiScan

The MultiScan measurement enables you to generate field plots from any frequency within the measured wide band span. This powerful feature is a major improvement and it gives an enormous amount of information. Looking at the screen dump to the right, the main part of the screen shows the field plot of the frequency selected in the top left graph. The top left graph shows the accumulated trace (a max hold spectra of all measuring points). The top right graph shows the wide band spectra from a user selectable spot on the field plot.

Import 3D surface models

Now you can import 3D surface models in STL file format and create measuring points that follow the surface at a fixed distance. 3D surface models can easily be aligned to the measurement using the 3-point alignment feature

Calibration option

IC measurement option

The Immunity software option allows you to measure the immunity against radiated electro magnetic interference of components, cables, PCB’s and products.

The new strip line calibration feature enables you to accurately measure the field strength of the magnetic near field and to compare measurements made with different probes and setups.

The IC-option improves the accuracy of your HR-Scanner. The high resolution real time inspection camera shows a microscopic view of the probe tip and the test object.

SCANNER MODELS

The HRE-Scanner comes with a set of four specially selected near field probes, a 30 dB pre-amplifier and two RF cables. To complete the Scanner system you would need a PC and a spectrum analyzer. Depending on your choice of spectrum analyzer you may also need an GPIB adapter (it only works with adapters from National Instruments).

The HRE41 scanner are exactly like the HRE1 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 storing the amplitude. This procedure is performed in every measuring position. More >

EASY OF USE

Earlier emission measurements had to be made by specialists. With the EMC scanner anyone can make a measurement and draw conclusions from the informative and easily interpreted re­ports. You do not even need to have access to a screened room to make the measurements. The software runs in Windows on a standard PC and is intuitive and user-friendly. Since the system is configurable for most modern spectrum analyzers, you can use your own and do not have to purchase a new one.

 

Using the EMC-Scanner during the early stages of design enables you to detect potential emission problems before they become integrated into the product and expensive to correct. If a product has failed a test at a test house, normally you only know which frequency failed. You don’t get to know the location of the source. The EMC-Scanner can help you find the source and repeated measurements while redesigning your product helps you lower the emission levels.

The EMC-Scanner can help you maintain a high quality in the production line. You can make measurements on samples from the production line and easily compare them with a reference. That way you can make sure

that, for example, a change of supplier for a component doesn't affect the emission spectra in a negative way.

WHY THE EMC SCANNER

1

You save time and money by reducing your need for expensive and time consuming full scale measurement.

6

You do not have to know what frequencies you are looking for thanks to the PreScan and MultiScan function.

2

You can see the emission at components level.

7

You can use your own instruments

3

Early in the design phase you can detect potential emission problems.

8

You can easily document (ISO900x) the emission spectra of your products in both design and production phase.

4

You can make comparative measurements to document the effect of a change in design.

9

You can subtract one measurement from another to remove ambient noise or to be able to see the difference between two products more clearly.

5

You can maintain a high quality in the production line by measuring samples and comparing them to a reference.
