| #20: Quick 5 minute Tektronix Mixed Domain Oscilloscope MDO4000 Demo This video is a very quick 5min demonstration of the new Tektronix MDO4000 - a Mixed Domain Oscilloscope. Its the first scope of its kind that adds a time-correlated Spectrum Analyzer to a Mixed Signal Oscilloscope, thereby giving you one instrument that includes 4 analog scope inputs, 16 digital inputs, and one dedicated RF input. The Spectrum Analyzer is very nice, large screen, basic spectrum analyzer which includes some very "non-basic" features. These include a Spectrogram display (to show spectral history of the acquisitions), as well as RF Amplitude, Frequency or Phase vs. Time displays. However, the REAL power of this instrument is that it ties all three of the domains (Analog, Digital and RF) together with a common acquisition and trigger system - which makes it possible to view signal activity on all inputs with full time correlation across the channels. The example shown illustrates the multi-domain capture of a Phase Locked Loop circuit as it is turned-on (enabled), receiving a command to tune to a new frequency, and then capturing the loop behavior as it slews and settles to the new programmed frequency. This example shows the ability to decode and trigger on a 3-wire digital SPI bus command that is being sent to the PLL, and capturing several analog signals and the RF activity during the entire process. This video just touches on a few of the features of this very cool new tool. https://youtu.be/x1oe45DP1_4 |
