Programmable DDS Signal Generator Counter, Koolertron Upgraded 60MHz 3.5inch Screen High Precision Dual-Channel Arbitray Waveform Function Generator Frequency Meter 300MSa/s

In contrast to its "little brother," this function generator offers a great deal more functionality for not an unreasonable amount of money. The only thing I would quibble with is In this case, it's an encoder rotary. My system can be a bit cranky at times, and it's sometimes acted as if I had turned it the other way. When it comes to turning it, patience is the key. I have no complaints about how smooth the turning process is. All the buttons have a pleasant feel to them. We like that you can enter numbers with the numerical entry keys. The dedicated and soft keys are arranged in logical order. Shortcut keys that are frequently pressed are arranged in logical order. Power plugs can be easily removed and are very easy to use You can insert it as long as you do it firmly! I'm not implying that you shouldn't re-insert it after it is fully inserted just that it will stay connected once it is fully inserted. I have set it to a NIST traceable calibration source using the firmware fine frequency calibration (in the settings for the [SYS] section). I found it to be almost right on the mark as it arrived. It's stable and on target within two minutes after a cold start at about 68 degrees F. There is a slight leakage of radio signal above about 15 MHz near the plastic enclosure that peaks around 30 MHz and a lower peak around 50 MHz with no cables. When viewed from about a foot away, it is almost invisible. Besides function/signal generators, there can be even worse ones. I have yet to find any untoward interaction between the two channels of output. It's a treat to use the handle because it has a positive locking action.

I'd like to add this function generator to my bench as soon as possible.

Three or more brand names are used to describe the same generator. For the price, it is an amazing piece of equipment. HP or Tek quality it is not, but my once expensive HP arbitrary generator produces a single frequency of 6 MHz. Koolertron's 80 MHz unit, in contrast, has two different independent arbitrary outputs, each of which can reach 50 MHz. Additionally, you can modify the phase relationship between the two channels by a tenth of an inch. As of now, I haven't tested the Koolertron for phase noise or spectral purity, but I would suspect that it will perform well based on the use of budget Observe how the screen shows a true representation of the selected waveform, including both the shape and the value of the I like how the unit is so light it almost seems like nothing is inside, except that the rubber bumpers keep the instrument from moving when I press.

Neither a cable nor a bluetooth adapter was in my basket. When I notified the seller , they responded immediately and provided me with all the correct links, provided me with the missing cable, and even gave me a 10 off as a result of Customer service was great and the product was great. I would definitely buy from them again.

In my opinion, 270 dollars for a signal generator would have been a good deal, but it turned out to be a lemon. The unit kept shutting down on its own. I wish I would have recorded videos before returning this. I'm glad I have Amazon Prime, it makes returning so much easier.

This is the best test bench for Ham Radio.

The service and building of guitar amps is what I do with it. High frequencies in excess of 20Khz are not used in my music. The software works well.

There was one downer today. The description is very I find the interface to be very intuitive. There are a lot of features that the "Quick Start" guide does not cover. You cannot find the program software on the server that is referred to in the book. Hence, I have not yet found the software and I am unable to download it. It's a bit harder to find information on the Koolertron website as well.

This application has a very straightforward interface, and is very functional. Automatic work is made possible by freely defining the waveform type (such as sine wave, square wave, triangle wave, arbitrary wave, etc. ) as well as the output time and sequence. Updates to the firmware can be performed at any time to fix bugs or as part of special customizations. You must press the corresponding soft key to confirm opening the update mode, then you must perform a one-time update The software on the PC can be used to upgrade the firmware. According to expectations, it works well. I'd say it's a very good function generator for the price.
