Review: Great product, works as it should. Nice display and options. See pictures.
Review: Initially worked great!!! Very intuitive logic design! User Manual fairly good and written by someone who has a good command of North American English! After entering a new set of operating conditions for both Ch1 and Ch2, I SAVED the entries, then powered OFF using the Push Button. Some 10 seconds later I again pushed the ON / OFF Push Button, the unit would not stay ON unless I held the Push Button IN. If I held the Button IN the unit seemed to program normally, but would immediately turn OFF as soon as I released the Push Button.

## Features

- 【Upgraded Signal Stability】Seesii Dual-channel DDS arbitrary waveform generator adopts large scale FPGA integrated circuit and high speed MCU microprocessor. The internal circuit adopts active crystal oscillator as benchmark. So the signal stability is greatly strengthened.
- 【Storage And Custom】 You can store 99 groups instrument state parameters set by the user, can be called up to Reproduce. Frequency output of Sine wave can be up to 60MHz. 200MSa/s sampling rate. It has 60 positions for saving user-defined waveform. In addition, it has a very good software package that allows you to create your own waves and frequency combinations. After you save them, you can disconnect the unit from the computer and use them for any applications you wish.
- 【High Precise】 Using Dual-channel DDS signal and TTL electric level output to generate precise, stable, low distortion output signal. includes Sine wave, Square wave, Triangle wave, Sawtooth wave, Pulse wave, white noise, user-defined waveform etc. each channel can be independently set the parameters.Duty cycle of each channel can be adjusted separately. Precision can be 0.1%.
- 【Frequency Meter】With linear sweep(Max. up to 999.9s) and logarithmic frequency sweep functions.Has a frequency measurement, period measurement, positive and negative pulse width measurement and counting function.The settings allow you to enter up to 20volts
- 【Lightweght Compact and Portable】With intuitive control panel, you can easy to control.This Signal Generator is the ideal instrument for electronic engineering, laboratories, production lines, teaching and scientific research. This is an important tool for both experts and newcomers

## Questions & Answers

**Q: Alignment for old AM radios, Will this work to produce proper signals to realign older antique tube radios?**
A: Yes it covers the a.m. frequency band and IF frequency band. You could set up a sweep to look at the band pass of the I F amplifier.

**Q: Can you implement a phase shift between channel 1 and channel 2.  For instance if I wanted to simulate a quadrature encoder?**
A: Yes, Function is there and verified with oscilloscope.

**Q: Can this unit generate pink and white noise in adition to standard waveforms?**
A: No, just standard wave forms.

**Q: Need instructions on how to generate am modulated rf.  is there a button for am modulation?**
A: It does not do AM or FM modulation. The “MOD” button actually turns on a “sweep” function, which is something completely different.

### ⭐⭐⭐⭐⭐ Review
*by G***G on 9 February 2025*

I thought this would be a nice little addition to my bench. I was wrong. First off, it's extremely lightweight and slides around at the slightest touch. Second, and most importantly, it's wildly inaccurate. I double checked it against my Rigol scope. 5khz sine @ 2v attentuation. While the frequency was accurate the voltage swung from 1.2 to 2.2 volts. At 500mV, my scope could barely lock on to it, that's how bad it is. It's useless for any work where you need precision. Avoid.
