Re: [TCML] Function Generator Question

[Sfxneon@xxxxxxx]

Greg,
 
It should probably have settings for minimum and maximum frequency and  sweep 
duration that will allow you to sweep through any portion of it's output  
frequency in a predetermined amount of time. This is used in many ways, like  
radio and television diagnostics, amplifier design and testing, or sweeping  
tuned circuits to find resonance points. There are others on the list that can  
tell you more about that than I.
 
You can also make it sound just like a police siren (when amplified) by  
setting the low and high frequencies somewhere between a few hundred and a few  
thousand cycles, and sweeping that with the sine, triangle and square wave  
functions. Being able to hear it will give you a good idea of how it  works.

I just acquired a used function generator from e-bay.  Very nice  looking 
"Protek" unit made in Korea.  Real bargain.  No user manual  though.  Range is 
<1Hz to 2MHz which should be fine for pinging  secondaries, tuning up primary 
circuits, coupling measurements, etc.  I  just have one question.  What is the 
"SWEEP" control for?  I turned it  on while monitoring the output on an 
o'scope, and it seems to repetitively sweep  the output frequency from low to high.  
What good is that?  Poor man's  spectrum analyzer?
