OUTPUT: = NOT the OUTPUT;
2, The output waveform (selected channel1)
1), When the task is 1ms, output waveform as shown below.
Photo 1, the Tektronix oscilloscope output.
The output square wave period T = 2.001ms, peak 25.2V; (the figure each dotted line bars indicate 1 ms).
The output square wave period T = 2.00ms, peak to peak 24V; (the figure each dotted line bars indicate 1 ms);
- when the task is 500us, the output waveform as shown below 3,4 follows:
In Figure 3, the Tektronix oscilloscope output graphics
The output square wave period T = 1.004ms, peak 24.4V; (the figure each dotted line grid, said 500us);
The output of the square wave period T = 1.02ms peak 23.6V; (each dotted line grid on the map, said 500us);
- when the task is 333us, the output waveform as shown below 5,6 follows:
In Figure 5, the Tektronix oscilloscope output graphics
The output square wave period T = 666.0us peak 22.8V; (the figure each dotted line grid, said 250us);
Figure 6, the DSO oscilloscope output graphics
The output square wave period T = 667us, peak 22.8V; (the figure each dotted line grid, said 200us);
3, Summarize
Compare the measurement results, we can see the the DSO oscilloscope with Tektronix oscilloscope is basically the same.The portability of a DSO is better, Tektronix smarter in the parameter setting and adjustment. But DSO price is only $199.00.
