New Standard for Price Performance: Bandwidth, Visualization, and Integration

Spectrum analysis and Multi-domain analysis:  
Enhanced color FFT function with peak search  
The enhanced color FFT takes your experience of oscilloscope-  
based spectrum analysis to the next level.  
– Color grade immediately shows you the frequency and  
amplitude distributions of your signal.  
– The frequency peak search eliminates tedious cursor  
measurements.  
– The peak search event lister provides frequency and  
amplitude information for up to 11 peaks, sorting them in the  
order of the frequency or the amplitude.  
– Set frequencies in “start and stop” or “center and span.”  
– FFT max hold, min hold, and frequency average plots are also  
available through the math functions. Displays up to four  
functions simultaneously.  
Figure 36. Enhanced color FFT with an automatic peak search and FFT  
histogram turned on. Min/max hold and average FFT also available.  
Multi-domain time correlated measurements with  
Gated FFT  
The new problem solving feature called “gated FFT” lets you  
time correlate the analog, digital, and frequency domain to aid in  
analysis and debug. When the gated FFT is on, the oscilloscope  
goes into zoom mode. The FFT analysis shown in the zoomed  
(bottom) window is taken from the period of time indicated by  
the zoom box in the main (top) window. Touch and move/flick the  
zoom box through the acquisition to investigate how the spectrum  
components change over time, correlating the RF phenomenon  
with the analog and digital signals.  
Figure 37a shows the Gated FFT correlating the turn-on of a PLL  
with an associated SPI command and the spectrum contents  
at a given time (the boxed area in the top/main window). By  
moving the Gated FFT zoom box, you can quickly see the  
spectrum contents at another time slot. Note, unlike the scopes  
with the RF input, you can actually see the RF signal in the time  
domain (channel 4 magenta trace) to quickly grasp its amplitude  
information as well.

and spectrum content at a given time span.  
Figure 37b shows the Gated FFT correlating the FSK frequency  
hop from 400 kHz to 3.2 MHz and its related I2C command. Again,  
the Gated FFT revealed the relationship of the hopping signal to  
the control command (I2C).

an I2C command (write 7 at 0x71 data 10).
