This is really helpful. With all the features in signal generators, I’m sure there are wide number of special cases … that become obvious to any individual in there speciality field, but that might not be so obvious outside that field. Eg using 2 signal generator adding noise, or adding harmonics, or specific uses of different types of burst modes., More videos on this topic would be wonderful.
Thank you, great demonstration! I recently started teaching electronics technology to high school students in a career and technical school in the U.S. and I had just covered this very topic with a similar (but not as extensive) approach. I wish I would have seen your video beforehand, as you were able to elaborate so much more information and more concisely. I'll certainly be tuning in more often to expand my 'teaching tool kit.'
Thank you so much for the awesome lesson! It's pretty easy to understand yet important in the learning process. Grateful for your time putting this together.
For synthesiser low frequency oscillators at 0.001Hz and below are very useful control voltages for filters and such like (especially if you're doing ambient music). when you get that slow, period does make a lot more sense than frequency.
Excellent demonstration! I like your style of teaching, and just subbed. I'm looking forward to looking at all your videos and the ones to come in the future. Appreciated!
Brilliant mate. I always wonder what people use all the different wave types and frequencies for with a signal generator. 99 times out of 100 I'm simply driving a motor with pulse width input. If you have any other ideas I'd love to see him.
@@LockdownElectronics Maybe I wasn't clear. This generator can combine two signals to produce an AM or FM modulated frequency. It is clear what he knows how to do from the description and the film, but modulation is not presented or I wasn't paying attention.
Good video although I suspect that if you have a sig gen you also have a DC power supply, but sometimes two sources are handy. I have been known to use the sig gen DC output with a negative offset to provide a -ve voltage for an op-amp.
You can get them on ebay but they do ship straight from China. Shipping is faster than you would think. I posted a link but it was removed by youtube I guess.
At about 4 minutes in you showed a formula to determine frequency not time yet you took the reciprocal of the frequency. The formula should show t = 1 / f .
I don't think so as the LEDS are feed from a common point it only needs one resistor at the source it doesn't matter if it's negative or positive it's just one common point .
@@RensePosthumus Hi I understand but only one Led is a light at a time depending on the pulse being negative or positive so you would only need one resistor so you would never draw more than one LEDs worth of current at a time the other led is turned off at least that's what I understand. I think of it as two diodes in opposite parallel only one can conduct at a time.
Not correct measurment, 10Vpp = 3,53Vrms because double Veff in sine wave ,one Veff = Vp/square root 2 In you video must be 20Vpp to Vrms = 7,07V That generator basically generates the amplitude in Vp In house outlet 230Vrms = 325Veff = 650Vpp
Who builds things , most just string together modules from flea ebay or back end express . With no idea how the thing works or its rating ! Fail safes design , fuses & grounding are non-existent or a after thought . ( After being the operative world ) .

This helped me understand a few things much better. Thank you.
Thanks. I needed more information before purchasing my first signal generator for my Electronics Laboratory Bench.
Bill, very helpful video. Thank You.

Excellent demonstration 👍
Thank you for expanding our thinking. Very interesting and useful information.
Great video, great teacher, thank you
Good job.

Do you have any information about modulation with this generator, or other similar equipment? Thank you.
Yes this generator will produce modulated signals in a variety of types, AM, FM etc...

You really should use a non symmetrical waveform to test if a DMM is true RMS
I love playing with lissajous figures with sig gens and an oscilloscope!
Can you post a link the distributor of Junctek signal generator i dont see it any where after a google search in USA thanks
You can get them on ebay but they do ship straight from China. Shipping is faster than you would think. I posted a link but it was removed by youtube I guess.
The 10v Peak to Peak voltage from the Generator should be 3.53V RMS on your meter. The output from the generator must be putting out 20V P-P?
No!
V / Square Root of 2 = RMS.....10V / 1.41 = 7.092V
@@FloppyDos What p-p does it measure on an oscilloscope?
Yes, you can see on the function generator that the *amplitude* is 10V, so p-p would be 20.
JUNKTEC ... what a name ^-^
JUNCTEK is the name!
Look up “WK” !
These Junctek generators have the display very cheap and mine faulty after 3 months of use

True it should show that but it should also be understood even with existing formula among most all of his viewers.
Yep
@@sethbergman3320 It's confusing
just a question: does not each led needs its own current limiting resistor?
+ many thanks for a year full of great video's!
I don't think so as the LEDS are feed from a common point it only needs one resistor at the source it doesn't matter if it's negative or positive it's just one common point .

55Hz.. :)
A nice compromise I felt....
