Demo 2: Tune signals in spectrum analyzer mode
In this demonstration, we will switch to spectrum analyzer mode to tune a signal with the 
flexible span/RBW, max hold, and PowerSuite features. A very useful function for this use 
case is {Global Center Frequency}, which couples the meters frequency in EMI receiver 
mode and the center frequency in spectrum analyzer mode. This simplifies switching 
between these two modes by taking the frequency of the suspect signal to spectrum 
analyzer mode and bringing the adjusted frequency back to EMI receiver mode to write 
back to signal list.

Step 3—Demo 2 Instructions for MXE Keystrokes
Select a signal from the list 
Couple meters frequency in EMI receiver 
mode to center frequency in spectrum 
analyzer mode by turning on global center 
frequency
[Mode Setup], {Global Settings}, {Global Center Frequency On}
Switch to spectrum analyzer mode [Mode], {Spectrum Analyzer}
Change span and RBW for a better view of the 
signal
Adjust the center frequency appropriately to 
centralize the signal
[FREQ], using knob to adjust the meter frequency to the center of the zoomed in signal
the frequency or amplitude varying signals
Switch back to EMI receiver mode
Note that the meters frequency has been 
changed to the same as the new center 
frequency in spectrum analyzer mode
[Mode], {EMI Receiver}
Replace the current signal with the new 
meters frequency
