Another 'scope question
Thanks all for the info so far. Now another one. The probe is set at
1X. The volts/div is set at 50 m. the time/div is set at .1 ms. So this tells me that each vertical division is 50 millivolts and each horizontal division is .1 milliseconds. The probe is clipped to the calibration bar. This bar is labeled as 300 mV 30mA ~1KHz. The display shows the square wave with 6 divisions vertical and just over 10 divisions horizontal. Using the VAR knob in the center of the time/div knob I can adjust the display to show exactly 10 divisions. When this is done is the display correct? Or is it the calibration bar that is wrong? Thanks, Eric |
