SiglentTechnologies SDG2042X Arbitrary Waveform Function-Generators, 40 MHz, Grey & Technologies SDS1202X-E 200 mhz Digital Oscilloscope 2 Channels, Grey

This is a very nice instrument. It is not cheap, but nice. It is also a lot less to the very high end signal generators. It is good for HF ham radio work. The capacitive touch screen is very handy and easy to use, but I would say the same for the button operated menu system as well. I had no trouble connecting to my LAN and using the PC software for this as well.

I purchased this after a friend recommended it when I said I needed a signal generator for troubleshooting work. I was skeptical as the product is made in China. But the quality is very good and the user interface is quite simple. It passed my usual test - could I get it to do basic stuff without reading the instructions. It has quite a range of capability - most standard waveforms (sine, square, triangle, pulse) are built-in. So is a noise waveform. It has an arbitrary function capability so you can enter a waveform via the USB or network interface (standard Ethernet) connection and it will then generate it and let you vary amplitude and frequency. The display is quite sharp and the screen is large enough to be easily read. The relatively small size means it does not take up a lot of space on your workbench or if you are carrying it around. A nice, well-made (though I did not open it up - I'm judging by the way the controls feel and work) product for a reasonable price. If I ever need to replace my Tektronix digital oscilloscope, having purchased this Siglent product will get me to look at their oscilloscope line as well.

Despite some issues this is a very capable unit with good performance at a very reasonable price.SOME RANDOM NOTES:o The fan is very quiet.o In general the user interface is good, although in some areas it is awkward.o I find the touch-screen to be useful for some things, and will often use both the touch-screen and the buttons together to make settings.o The manual is very basic, and inadequate in many areas.o The EasyWave software for creating and downloading arbitrary waveforms pretty much sucks. It's also Windows only.o The unit has two arbitrary waveform generation modes: DDS and TrueArb. They behave quite differently. The manual doesn't explain at all well the differences and how to get predictable results from either mode. The EasyWave software doesn't help at all: it will show you one thing on the computer screen and the unit will generate an entirely different waveform. After many hours of experimentation I still haven't figured out how to get predictable results, even though the waveforms I'm trying to generate should be trivial to create.o The hardware is the same for all three units in this line. It's possible to start with the 40MHz unit, and get unlock codes for the higher frequency units.o The only difference between the three units in this line is the maximum sine wave frequency. The maximum square-wave, triangle-wave, etc. frequencies are the same, and are lower than that for sine waves.o There is a long discussion of issues and findings with regard to this unit on the EEVblog forum, including many oscilloscope screen shots, at:[...]

I previously had a similar Rigol with a lower band width. I bought this Siglent to gain a little higher frequency. I put it to use right away, without having to refer to the user's manual (not supplied with unit). I have continued to use it off and on over the last few weeks, with no issues or needing to refer to the manual. The Rigol was just as good, and don't really see any advantage of one brand over the other.I have successfully used this for alignment purposes on several boat anchor receivers because some of the frequencies needed were not available on my HP-8656B. The alignments were spot on, and I have not had any issues.

Have not done a full test of the device yet. Hope I have the time to do it next week. It arrived properly protected with no visible damage.

Generator arrived on time, appears to be working as expected - I'll be checking it with a spectrum analyzer and scope in a few weeks when I can borrow those items. For now, I can generate/modulate a tone that i can hear on an AM Radio and CB radios, at the frequency I expect, so I assume it's good on the rest of the band.Fan is very quiet. Unit has USB and Ethernet interfaces. Additional programming manuals and documentation can be downloaded from Siglent website.As an example, the firmware would not allow me to program a 1% duty cycle directly (5-95%), but by specifying a number of cycles at the desired frequency in burst mode, I was easily able to program a 27.12 MHz burst of 271 cycles every 1mS (a 1% duty cycle on a 1KHz pulse output at 27.12MHz), and program the amplitude as output voltage into 50 ohm load.I have no issues with the unit yet, it works as described. included a short quick start guide and a CD with software and additional documentation.

I bought this signal generator/ARB for use testing electronic components and circuits. It is quite a bargain, offering good performance at a very reasonable price. The display and controls are easy to use. So far I've only used it for manual testing, but it has USB and Ethernet interfaces, which I will use in conjunction with similar interfaces on my oscilloscope to set up automated testing.

The SDG2042X works as advertised, the interface is fairly intuitive.A few notes:Siglent recently added the ability to combine the two channels internally with the latest firmware update. Hopefully they continue to support this with future firmware updates.The arbitrary waveform generator is UI is terrible and Windows only. However, the signal generator comes pre-loaded with dozens of waveforms and I haven't needed to load any new ones with their software yet. If I do need to define an arbitrary waveform, I plan on sending it over the programming interface they document on their website rather than use their software..I didn't see anything in the manual about this before buying it, but the signal generator does support setting the output power in dBm while in 50 ohm output impedance mode. The lowest supported output amplitude is about -56 dBm.

As a radio repair tech, this instrument is perfect for 2-tone tests of SSB transmitters. As well as injecting signals for IF circuits that are missing for troubleshooting etc. My only regret is I should have bought the 60Mhz unit. Otherwise. Excellent gear.Electronics-Tech

Este generador lo añadí para trabajos en los que requiero dos canales, funciona de maravilla ya que acepta archivos csv de cualquier marca de osciloscopios, lo uso con tektronix, agilent y siglent, con este último se pueden hacer gráficos de bode para respuesta en frecuencia.

This Siglent function generator is a very high quality product and low on price compared to other brands. It has almost all the features you may ever needed and expected a long reliability from Siglent brand. I found the two channels are not quite identical, with channel one output has a better accuracy than on channel two. Overall, it is still my favorite workhorse on my bench.

Excellent dollars worth of instrument. Very robustly constructed. Easy to find your way around the user interface. Simple to load waveforms from Excel. We have 3 of these now, and they're an excellent lab resource.
