Looking for a Signal/Waveform Generator.
« on: August 08, 2024, 01:11:21 am »
I work as an aircraft mechanic to do some functional checks, I am in need of a sign wave generator that is capable of putting out at least 3VPP and a wide range from 0hz to 5000HZ.  The last time we ended up borrowing an older box with just knobs and no display, and using a fluke 179 to watch the frequency and voltage to dial them in. I see some more expensive ones on amazon but any recommendation on a good unit under the 500$USD range that would get this done and be good quality?  Something with a display that is capable of being sent in and Calibrated?

Something like this is what I was hoping for.

OWON Waveform Generator,30MHz Bandwidth, 125MSa/s Sampling Rate, 14 bits Vertical Resolution, 8K Waveform Length,5 Basic Waveforms,          <Cheap but claims 4VPP but would rather not waste money.

Siglent Technologies SDG1032X Arbitrary Waveform - Function Generator            <Middle of the road price.

More information on the test I am asking about.

adjust the Sine-wave Generator (2V / 0-1000Hz) to give the frequencies at between 1.8 Vpp and 2.2 Vpp. Read the NR indications on the triple indicator.
____________________________________________________________________________________________________________
Connect the sine-wave generator (2Vpp / 0-5000Hz) to the connector N1  of the N1 speed sensor as follows:

NOTE
A frequency of 4100 Hz simulates N1 > 50 %.
A frequency of 3900 Hz simulates N1 < 50 %.

Any Advise on something that would complete this and not be overly expensive but also be of a good quality would be awesome.

Thanks,

EDIT: Or if this is the wrong section to ask this question direct me there.

pretty much any modern function gen does what you are looking for.

The least expensive thing (not from aliexpress) with decent capabilities looks like:

$148

2Channel
30MHz
10Vpp
Full arb

I have no experience with this specific thing, and I'm not sure I'd buy that for EE design bench work, but for some testing signal source it's probably overkill.

The prices and features and accuracy go up from there:

Just be careful with what voltage means in the context of most electronics signal generators (and the calibration checks), the amplitude is measured into a specific ideal load (usually 50 ohms) and the voltages will not be exact otherwise.
