Atten ADS1102CAL Oscilloscope

For some time now, the need to have a scope became greater. There were so many projects I could not properly implement, because I didn’t have this tool. Finally I came to decide for a digital oscilloscope.

ATTEN ADS1102CAL vs Rigol DS1052e were the two options left for considering. Both in the same price range, having a slim design and fancy features such as USB connectors for plugging in a USB Flash and snapshoting the traces (I use that a lot!). The former a 100MHz scope with almost zero reviews (at the time of this article) and the latter limited to 50MHz but with a hack available to boost it to 100MHz and with plenty of feedback, posts and articles from the user community.

Not an easy choice, but I opted for the Atten in the end, assuming it will perform at least as good as the Rigol, and that the lack of reviews is not an indication of its quality. Lucky for me, this assumption was correct.

The ADS1102CAL is a great addon to my workbench, and a valuable tool, that allowed me to push my project further. The uRADMonitor would not have been possible without it.

• Manual, tracking, automatic cursor measurement function;
• channel waveform and FFT waveforms at the same time split-screen display;
• Analog channel waveform mesh screen brightness and brightness adjustable;
• pop-up menu display mode, the user operation more flexible, natural;
• rich interface display style: classic, modern, traditional, simple;

Update October 4, 2013
I got a new probe today, very similar in construction to the original two included in the package. I like that they match nicely. The new probe is a high voltage, 100:1 , 100M impedance, rated for 2KV max , that should prove extremely useful when measuring the output voltages of the inverters in my radiation detectors. It is marked as P4100.
P4100 manufacturer specs:

Bandwidth: 100MHz
Rise time: 3.5ns
Attenuation Ratio: 100:1
Input Resistance: 100M ohm +-2%
Input Capacitance: 6pF
Maximum Input: 2KV Working Voltage(Vp-p)
Compensation Range: 10pF-35pF
Operation Environment: 0-50C, 0-80%RH
Storage Environment: -20 to 60C, 0-90%RH
Size: 110+-2CM
Weight: About 65g
