In order to take advantage of the ‘measure at marker’ method in the Agilent e444x series EMI spectrum analyzers we had to create 2 new actions. They are the measure peaks and OATS for PSA. We still need to expand this to ‘Scan peaks’ action next. If you use the legacy actions, you will not get the correct readings.
You must have the EMI option installed on the analyzer to take advantage of this.
