Hello,
I am going through a phase where I am testing all my common effects plugins, particularly saturators and sim amps, using a couple of analyzer plugins (EQ curve, phase, spectrogram, etc). As part of the process, I am using Melda's pink/white noise generator. I am wondering if there is such a thing as a DAW sound generator plugin that produces frequencies throughout the frequency range (e.g., 20hz to 20khz), as a noise generator, but more consistently like a signal pure sine wave. With noise, the frequencies are jumping up and down consistently. I would like to also be able to test the plugin with a more consistent spectrum.
Like a noise generator but more continous, smoother

White noise is as smooth as it can be...
The only signal which can be consistent is a single sine wave. Already two sine waves which are not in a rational ratio would jump or beat...
There ain’t no such thing as a consistent spectrum with noise... Just average it a bit, should be sufficient...
But I would test plugins with my ears and with musical material...

Not sure what is going on for you but the melda generator is ok so there should not be any particularly audible changes to the frequency spectrum - there are different ways to think of white noise but for all of them it is the same spectrum over any interval of time

Thanks, everyone. Helpful information. Using averaging and smoothness function in MMultianalyzer helps to tame the results.
I find it invaluable to use both my ears and analyzer plugins with both musical material and signals generated specifically for analysis (sweeping sine wave, white noise, etc). In my opinion, it is a good idea before using a saturation plugins or other effect plugins for that matter throughout our mixes to independently analyze its EQ curve, phase-shifting, and spectrogram, using analyzer plugins such as the free Bertom EQ Curve Analyzer and Span, to gain a better idea of how it works, what "artifacts" it may introduce, and how they compare with other plugins. I know way more what my plugins actually do after analyzing with Melda's tools and Bertom's EQ/Phase analyzer.
I recently went through my sim amps and saturation plugins, and I was surprised by the wild phasing and frequency response of some of them, something which could negatively impact the original signal when used in parallel. Interestingly, the saturation plugins and the sim amp I generally preferred displayed, what I would consider, fewer artifacts at moderate settings; they did not have excess phase shifting, a substantially modified EQ curve, or audible aliasing, for example. True Iron is one such plugin that performed well to my specifications. In terms of free plugins, Softube's Saturation Knob, Voxengo's Overtone EQ saturation, and Chow Tape Model (emulation) plugins also performed well.

Most (if not all) audio editors have a noise/tone generator built-in. this one is free:
