Today I had trekked down to the post office (missed two delivery attempts apparently) and brought home my new.. Tektronix 2215 oscilloscope! It was more awkward to carry than heavy at least.
After finding out the calibration knob on the time base had to be clicked all the way to the right, I get now a stable waveform and the calibration signal is excellently clear and stable.
-----------------------------------------------
(Nevermind next bit, thank you amspire!)
I got so excited I had to make some sort of signal, so I through some code on an Arduino. My question is: Why does it have a sluggish fall like this?
Now of course I can consider that PWM/digital devices do not care about that slope, although I'd rather understand if it is the Arduino being lazy, the cabling and whatnot inbetween making some impedence/capacitor? or the scope probe itself (even if near same frequency as the test signal)
Silly code was this: digitalWrite(9, HIGH);
delayMicroseconds(100); //10% duty @ 1kHz, or something
digitalWrite(9, LOW);
delayMicroseconds(1000 - 100);
---------------------
Also on to caring.. With some common sense I have considered:
- Position wave forms off screen when not in use
- Turn intensity down to something reasonable, as it is all visible to me anyway
- Turn off if not using for more than 5 minutes
Maybe the last one I am concerned about, does turning the screen on cause more wear and tear than leaving it on for say, 5 minutes I am not using it?
What are some other tips for care?
The handle seems very tight against the case, is it supposed to pivot to go under the device to raise the screen up, or is that something different? May try some WD-40 if I get the nerve to.
