    Arrived before the announced deadline of 1 week. The packaging is intact. The set is 100% + gift TTL bluetooth board B-91 for communication with a smartphone application. The quality of the signals corresponds to those requested by the manufacturer. Extremely easy to set up and operate. The price is lower than the quality of workmanship compared to other brands. For a home laboratory it is more than enough. I am very satisfied. I recommend !

    Fantastic signal generator. Even though the specs say things like the square wave will go up 30Mhz, by then it is starting to look a lot like a sine wave and by 35Mhz it is just a sine wave. I've found the highest usable square wave is around 15-20Mhz, which is still very awesome to be honest. Interface is clean and easy to use. It has plenty of wave types and settings such as phase and modulation that work really well. I love being able to cleanly pump out 25Volts at lower frequencies which is great for the automotive electronics projects I work on. The software is oretty crap, but it works. I only use it to create arbitrary waveforms that I store in the device and then never have to use it again. Mine came with a WiFi adapter so I can use the phone app. I don't. It's bad. Overall I'm very happy with it.

    Received, read the manual, and tested - delightful device ! It came with a little plug in Bluetooth device to use an Android phone or pad to control the PSG9080 - which would allow to move the PSG9080 off the bench and control and read it from the Android device instead of its own screen and controls. I found that Android 7 devices worked with the app to link automatically to the Bluetooth card, but Android 11 did not work. The Bluetooth device shows as BSG045 and if I can get the pairing key for it, can possibly get the Junteks app to connect on Android version 11. Appreciated that the PSG9070 will happily do frequency sweeping and display the envelope on a modern scope, as a way to determine frequency response curves of tuned circuits. One thing that I want to do is make a helper device to safely present a frequency response curve onto a vintage O'scope. The helper device has to present a very high impedance to the X-sweep output from the scope of 2 Meg Ohms, convert the +250 Volt ..0 Volt triangular waveform to +5V ..-5 V waveform that the PSG9080 inputs as external VCO input. The helper device also has to wideband amplify a signal coming from the DUT, and pass it through a diode to get a low frequency (circa 38 Hz frequency response waveform to feed into the old O'scope's amplifier.). Photo of an old O'scope included.. You might think "Why bother with adapting to vintage gear?". The reason is that modern devices, especially signal generators are far easier to use than old devices, and adapting like this reveals what engineers used to have to work with. It is educational and instructive.. Thank you for a great instrument, and long may it continue to work !

    Wonderful Equipment! Arrived in perfect condition. From China to Brazil came in 3 days. But unfortunately the mail here takes a while. Congratulations to the salesman and the Banggood team. I have now purchased a Hantek DSO2D15 Osciloscope More not yet shipped... I am on hold! I recommend Bangood...Congratulations

    Product arrived near the end of the expected time frame. The status was "In transit" from beginning puff placing order, until the last couple minutes of arriving at my community postal box. (It was a very long feeling wait, with no accurate status update.) However, it appears as described - works. On initial power-up, you select your language English/Chinese), and you're basically ready to go. Used a little oscilloscope to compare a 1kHz @ 6.6Vp-p @ 50%, set on the PSG 9080. The oscilloscope read it high @ ~1.1kHz, 6.7Vp-p, and from 41-59% duty cycle. ( It'she oscilloscope is not properly calibrated so would read about 10% higher than what it receives as input. No surprise there). Overall a decent price of equipment.

    Gerador de função excelente, estabilidade na frequência, amplitude, onda... Recomendo atendeu as expectativas.

    The ease of use is good. You can do one operation without reading it manually. The performance is also practical enough. The specs seem to be false. The amplitude and offset seem to be slightly off the display, but it's okay to check it externally. ANA Group's OCS made delivery to Japan safe.

    Nice little waveform generator. OK for hobbyist but not usable for professional work. Signal modulation has some shortcomings. e.g. for FM modulation, carrier is downshifted by several kHz when switched on with no audio signal, looks like there is some remaining DC component. So far, there is no "Service manual" available. This could be useful to perform some adjustment.
