Assembled as instructed. Square wave works fine, but triangle and sine do not. They produce non square waves but def not sine or triangle.

A
  • 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

Q

What is the maximum power draw on this unit? I want to incorporate this into a prototyping board I'm making and need to calculate the combined draw.

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

Q

Can someone verify a power supply that I can purchase with the right size of barrell connector? (or tell me what size of barrell connector)

A
  • 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

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.

If so use careful soldering. see less

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

Q

Can it output lower than 1hz, say 1/2 hz, or is 1hz as low as it can go? I'm considering it for a modulation source...

A
  • No,not with any stability.

Q

I have read the xr2206 can be used to block elf. is that even possible with this?

A
  • 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...

Q

can this be used for milliamp

A
  • This is a function-signal generator. I don't know in what regard you are referring to as "milliamp" (current).

Q

Can this be used to test and align an am tube radio? if not, please suggest one that will. thanks!

A
  • 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

Q

What is the polarity of the power input jack?

A
  • 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.

    I have an old oscilloscope from the '80s, made in the USSR, and wanted to use this to experiment with it. Very neat project, clear(ish) instructions, and works perfectly for light experimentatin. Thanks! Oh, and it came quickly, too.

    works fine - still playing with it. Some assembly required - I'm not great at setting down soldering, but it seems to work OK, so I apparently didn't mess anything up. Operational instructions would be good - for some reason the amplitude is high CCW, low CW. Maybe I installed something backwards, but maybe that's just the way it is.

    This was an easy build until I got to the case. The bottom of the case was designed to a flat board. Even with sever clipping there screws for the board did not work properly. I got it together after a fashion only because I wanted the labels on the top cover showing were to put the jumpers. If you didn't already have some knowledge of electronics knowing the short (negative) leg on the polar capacitors should go ground which was marked by some lines on the board. I used and Arduino with the IDE on a Raspberry Pi to get the square wave in the picture. Use the example sketch for using an analog pin to measure voltage.

    Neat little Function Generator, purchased next to my Oscilloscope to help learn a bit about its operation. Overall, the kit is complete but the casing is a little bit delicate (I managed to ham-fistedly over tighten a corner and break the plastic). I reassembled it a few times to find an optimal fit and a little super glue did wonders. The actual board and back plate could use some standoffs to account for the variation of height on the underside once the components are soldered but it works. Fun little project, the power supply noise affects the signal pretty adversely. Running from a small lithium battery seems much more stable when looking closely at the waveform.

    This is a fairly simple kit to assemble. The instructions are fair, but the info you need is there. With a little patience this can be assembled by a beginner. Worked as expected and the case was a nice touch. Space for a 9V battery would have been nice but at this price, no complaints. I didn't "NEED" signal generator, I just wanted one to experiment with so this kit was a good value for me and what I needed. No, it is not lab quality equipment but you cannot expect that at this price range. It works well for me.
