Good advice to stick with reputable manufacturers. Just want to point out that Keysight is the same as Agilent which is the same HP.. The company has segmented with new names over the years to focus on different markets.Also, try and buy from a manufacturer who's been around for a while.
Keysight (was Agilent, which was HP... so plenty of history behind it) is a top professional brand -- one of the big four (the others being Tektronix, LeCroy and Rohde&Schwarz). What you're getting there is the educational version: same front end as the bigger models, but lower bandwidth, less memory and reduced software feature set (e.g., serial protocols are missing SPI, CAN and LIN).Hi,
Just wondering if anyone has any thoughts/experience with this scope?
EDUX1052G Oscilloscope: 50 MHz, 2 Analog Channels, with a Built-in Waveform Generator
Great. But again, bear in mind that those feature are really just for basic measurements. For example, if you want to study how well some audio gear is performing, you would use a USB audio interface to output the test tone, record the output of the device and generate an FFT with software because the resolution of the results will be much better. Oscilloscopes are designed to be fast, not high resolution. The ADC on that scope is only 8 bits. With some over sampling finaglery, it's made to look like 10 bits maybe. So the resolution is not good good enough to measure THD or see harmonics at 90 dB down. The function generator probably isn't very good either because the OS is just some embedded thing so just a sine output alone is probably not even anywhere near the THD of an op amp you might be trying to measure.Thanks John and Neil,
I've been in touch with Keysight here in Australia, and they have been very helpful. As noted, the EDU range is geared towards education, and there is a lot of documentation, as well as tutorials and built-in test tones that I'm going to make the most of. My main interest is to test my amplifiers, compressors and other gear I build, so I think 50MHz should be plenty of bandwidth. The EDUX1052G has the features I'm most interested in - built in function generator, comes with a Bode plot training kit, FFT, gain and phase Bode plotting, DVM and frequency counter.
Ticks all the right boxes for me.
I wouldn't say it's "noisy". It's just that it doesn't have the range to "zoom in" on part of a large signal. So it uses a stepped attenuator on the input to make the signal use as much of the ADC range as possible. If you've ever used a digital scope you might notice that the vertical scale is stepped and not continuously adjustable and there can be a clicking noise as you change the vertical scale. That's relays clicking as it steps attenuation.SNR (50 Ω load, 500 MHz bandwidth): 40 dB (typical); 30 dB (min).
So yeah, very noisy compared to what I can get out of my DAW. Should still be useful though.
