The Equalizer uses externally measured frequency response data of external equipment to internally
calculate the required level correction values. The frequency response data is entered in data tables
which can be stored and recalled together with the calculated correction values. After activation of the
Equalizer, this correction data is used on the generated waveform. I/Q and modulator frequency
response data is edited in different dialogs,
I/Q
or
Modulator
dialog. Thus, correction data for different
measurement setups can be calculated and stored on the instrument.
Each dialog displays in several graphs the frequency response contained in the loaded correction list
and not the internally calculated correction values.
Areas of the graphs can be zoomed in by pressing the left mouse button and selecting the desired area
in the graphic window directly. A
Zoom Out
button is shown for returning to the original size.
The instrument compensates frequency responses of RF modulators. The region of interest is the
accessible bandwidth of 200 MHz centered on the RF carrier frequency.
