What should I know about setting up an oscilloscope?
Setting oscilloscope controls, calibrating the oscilloscope, connecting oscilloscope probes, and compensating the probes are also described, along with basic oscilloscope measurement techniques. Proper grounding is an important step when you set up to take measurements or work on a circuit:
How many channels does a mixed signal oscilloscope have?
Most oscilloscopes have at least two input channels and each channel can display a waveform on the screen. Multiple channels are useful for comparing waveforms. The front panel of a Mixed Signal Oscilloscope (MSO) will also have digital inputs.
How is a square wave reference signal used in an oscilloscope?
Most oscilloscopes have a square wave reference signal available at a terminal on the front panel used to compensate the probe. General instructions to compensate the probe are as follows: Attach the probe to a vertical channel. Connect the probe tip to the probe compensation, i.e. square wave reference signal.
How does peak detect mode work on an oscilloscope?
Digital oscilloscopes with peak detect mode run the ADC at a fast sample rate, even at very slow time base settings (slow time base settings translate into long waveform intervals) and are able to capture fast signal changes that would occur between the waveform points if in sample mode (Figure 23).
How many samples per second does an oscilloscope record?
The oscilloscope is recording 5.00 GS/s, i.e., 5×109 5 × 10 9 samples per second. Channel 1 is used to control the triggering of the waveform. Triggering occurs on the rising edge of the channel 1 waveform. The image is centered at T →▼0.000000 s from the trigger point.
What are the controls on a mixed signal oscilloscope?
The front panel of a Mixed Signal Oscilloscope (MSO) will also have digital inputs. Some oscilloscopes have AUTOSET and/or DEFAULT buttons that can set up the controls in one step to accommodate a signal.
