Now enable ERS correction and the difference plot will now change

This is now the corrected result and shows the values as would be measured on a perfect OATS.

It can been seen from the final corrected plot that this product's emissions fall below the limit and that this product passes

Select the limit line you wish to test to.

With the product switched off, scan and process the ambient to obtain a stable background signature.

Take the current trace of the background and copy it to the stored trace.

Switch on the Unit under test and take another sweep.

Switch on the difference trace.

Now switch off the current trace and stored trace.

The signal levels from the ERS are then measured.

Having set out your test site, you then use the ERS calibration mode to automatically calculate the errors of the site.

The software automatically searches for the location of a reference frequency.

The ERS calibration data looks like this.
If you had a perfect test site this is the plot you would get.

To calibrate your test site using your ERS you need to load the calibration data for the ERS you are using.

The background level is then measured with the ERS switched off to get a complete picture of the test site.

By processing these results and comparing with the ERS calibration data, the test site correction data is calculated by the software.
