RIGOL DS1052E: http://toolboom.com/en/Digital-Oscill...
Back in 2008, Rigol, being a startup company at that time, released a product line of DS1000E series oscilloscopes. The price-quality ratio was so good that the oscilloscopes had no competitors and quickly became popular receiving numerous awards. In fact, the DS1052E became a consumer choice product. Then, 6 years later, Rigol decides to reproduce former success and released the series of DS1000Z oscilloscopes.
During early production, the company released the models with the bandwidth of 70MHz and 100MHz, the price of which, therefore, was a bit higher than the price of Rigol 1052E. In a while, Rigol decided to fill in this gap by producing the DS1054Z model. Actually, the company has created an internal competition between the models, because these oscilloscopes are sold in the same price range. The difference in the price is about 15%. Now, let's find out is the new DS1054Z oscilloscope able to overtake the leading model DS1052E.
The other obvious advantage is the availability of wide screen. DS1052E model comes with 5.7 inch display with the resolution of 320x240 dots per inch. The DS1054Z model has the 7-inch LCD diagonal and the resolution of 800x480 dpi.
Also, the Z-series oscilloscopes have another advantage over 1000E-series. This is huge memory capacity of 12Mb unlike 1Mb of the 1000E-series and the high speed data capture of up to 30 000 waveforms per second. Now, I will practically show this difference.
For example, let's start with RIGOL DS1052E. I'm providing certain signal to the input, let it be square waveform and we are having the time-base of 1 microsecond. Let's change the time base to the level of 1 millisecond – 1000 times more. Pressing the "RUN/STOP" button – the signal is stored in the memory and now we are trying to expand it thousand times to have a closer look at the signal. As you can see, the signal almost has nothing to do with square waveform due to significant distortions. And now, I'm going to make the same operation with the RIGOL 1000Z model. Setting the same time base of 1microsecond and let's modify it in 1000 times to the 1 millisecond level. Expanding the chart. As you can see, the square waveform stays the same – no distortions that is the primary advantage of 1000Z series oscilloscopes, a capability of capturing big data volumes without distortions.
And now let's try doing the same operations with a signal of more interesting shape. Therefore we are having a signal. The time base of the signal is 500 nanoseconds. I'm saving this signal as the reference signal for further comparison. And let's change the time base 1000 times to 500 microseconds. Here we go. I've just pressed the "STOP" button and we expand the signal to 500 nanoseconds. At first the signal looks unchanged. Let's compare it to the reference signal. As you can see the signals are identical, no differences can be visually detected. Then let's change the time base 10 000 times. I turn off the reference signal. To 5 milliseconds. Now I expand the chart. The signal remains the same. Indeed the signal, in fact, corresponds to the reference signal. Let's "torture" the device for the last time – I will change the time base 100 000 times, to 50 milliseconds. The signal has been stored to the memory so I'm expanding it. As we can see there are slight angularity and distortions at the peak values. Showing the reference signal. Obviously, the signal is practically the same. In other words large data storage capacity and high speed data capture provides DS1000Z series with capability of analyzing large volumes of data. That means that I have received big data volume, magnified it 10 000 times and did not lose signal accuracy. The E-series oscilloscopes are not able to operate like that.
I believe you have witnessed everything. The DS1054Z oscilloscope leaves behind the DS1052E in the same price range. Let me remind the major advantages:
first of all, 4 input channels against 2;
12Megabytes memory against 1 Megabyte;
high speed data capture of up to 30.000 waveforms per second;
significantly more trigger options;
an option of digital signals decoder installation;
