Questions & Answers
Not sure what is used, if anything, for output conditioning circuit but have you considered loading the output? try a 600-ohm 1/2-watt resistor across the output at @10% amplitude... these things are typically spec'd at 600-ohm impedance

According to stock spec sheet...8mA...measured at pin 1...its just a signal generator...not a driver...very low current

The instructions, and schematic had that information, provided you did get the schematic. The connector is a 2.5 mm, center pin positive connector. As for the power supply, a 9 volt battery connector, and a 2.5 mm connector soldered to it will do. Do not exceed 12 volts. More voltage is not better. 9 volts will do fine… see more The instructions, and schematic had that information, provided you did get the schematic.

More voltage is not better. 9 volts will do fine. If all you have is 12 volts, a 9 volt 3 lead regulator would work. The device package should have a useful, basic regulator schematic on it, if not, look it up on the web. These regulators are as common as dirt, and inexpensive. Best power supply, for cost and ease of use, the 9 volt battery and connector clip. see less

This cannot just be set to a certain frequency. You have to turn the dials and use the clips to select the correct frequency range and then try to reach your set frequency with the two frequency dials. So, no this might not be what you are looking for, but if you just want to create adjustable sine waves in a cheap man… see more This cannot just be set to a certain frequency.

I had issues with the case clearing the power input connector, as well as a tab and slot in another area not aligning properly. The maker has been told about this. One other point, make sure the connector for the outputs is turned outward, so that the side where wires are connected for the output are indeed facing outward. Other than these issues, if a person is experienced, the bad directions for assembly can be set aside and just follow the circuit board pattern and values to assemble this very good test device. The resistor values may be hard to read, so use an ohm meter to find the right part to go to which position. Be careful, take your time, and it should all go together quite well. Other than the case issues, and the very bad assembly directions, it IS a good signal generator. see less

No,not with any stability.

The xr2206 is a monolithic function generator. The e.l.f. or Extremely Low Frequency spectrum is a range of frequencies of 3 ~ 30-hz. If you are trying to block this specific range, I am not sure that is even possible since wave propagation in this range is 100,000-10,000 km and very close to earth-ground...

This is a function-signal generator. I don't know in what regard you are referring to as "milliamp" (current).
By Tessa on February 4, 2018
This device as a signal generator, a frequency counter and an oscilliscope are the devices needed to set up an AM radio. Remember, the IF or intermediate frequency is 455KC. Look for the set up process on youtube.com

The data sheet that came with mine, under 4.3 indicates "center positive / barrel negative". It also specifies 9-12 volts. It all worked for me.

The unit must be assembled. It's a kit. It was fine for me, but the fit&finish isn't that good. Some pieces are loose, the electrolytic capacitors were too tall for the enclosure to close, unless I was building it wrong. I put in shorter capacitors that I had anyway. The output is ok, sine wave looks fine, but IT HAS A DC OFFSET of about 3v. For my application, (I build tube guitar amps) I had to add a capacitor in series to take out the DC offset. Coarse control works as expected. Fine control doesn't seem as fine. Amplitude control does not go lower than 500mVp-p. I think maximum is 7Vp-p. I haven't tried triangle or square waves yet, not really necessary for me.

I installed these components in about an hour and it immediately started working. The waveform is as shown in the advertisement, but the sine and triangle waveforms have significant DC offset components instead of being ground-centered. Small general purpose generator for workbench. The frequency range is larger than advertised, which is good. The power supply must be adjusted for normal operation.

I got this kit because I needed a cheap frequency generator to troubleshoot audio equipment. Let my 13-year-old son assemble it so he can learn some electronic techniques and how to solder properly. He did a great job, it was perfect the first time! Here are some tips to help you, some things that are not immediately obvious.

The XR2206 is a fairly good part and this product uses the basic functions to provide a good signal source over the audio range and beyond. I bought it as an add on for an inexpensive modular synthesizer. All the pieces do not fit together well. The power connector is too long an interferes with the side. The leads on the back must be cut and files for the bottom to fit. But it does make sine, triangle and square waves over a wide frequency and amplitude range and it is tolerably temperature stable. The datasheet for the part will give you ideas for adding functionality and improving performance if you like hacking hardware.

to couple with the Quartz / frequency meter tester, this makes a cheap amateur lab generator. Weird behavior in the high frequencies but quite correct to use in LF generator (0-100kHz). Attention: - put a 10k + 10k voltage divider at the output of the square signal (10V) to enter the frequency counter at 5V.
