Is the compensator output on DSO protected?

[truhlik_fredy]

At the moment I want for one-off usage (perhaps 20minutes) a simple function generator. And I have Rigol DS1052E, there is the compensator output for adjusting probes. It's 1Khz and its suits my needs very well. But I don't know how well its protected, like when I will draw to much current, or short it out. The device should not draw much current but just for the case. Its silly idea and I don't want to regret it.

well as mine mysteriously does not work anymore I would say no. My only explanation for mine is that I accidently shorted it. I suggest using a buffer just to be safe, Failing that throw a 555 timer circuit together or use an MCU

I will make MCU one, just I had this lazy evil thought to make shortcut and use the compensator for it. Thanks to turning me back (i was close )

yea you best use and MCU, it is as easy as flashing a led, no point in risking blowing your scopes calibrator, I've done that somehow

But if 1 kHz is all you need, just isolate the Rigol's calibration output with a voltage follower op amp to provide driving output to your load.  For this app you can use any op amp you have that is anywhere like a 741.

 

But if you do have an op amp handy, just make an oscillator with it, and save your worry:



If you don't have an op amp, you aren't picky about the output waveform, you can make an oscillator with any one of at least a transistor, op amp, or logic gates, and then at least a capacitor and some resistors.

Thanks, I was thinking about something like that but I was afraid that I can touch the ground near by the compensator output and I will short it before it goes to voltage follower. But thanks anyway.

Op amp circuits are nice, but you ideally should have as fast a rise time as practical.  Make a simple oscillator with a 74HC04, buffer it with a couple of more inverters in the HC04 and you will have a nice fast rise source.
