Oscilloscope chooses appropriate storage depth, also called record length
Storage depth is a measure of how many sampling points an oscilloscope can store. If you need to capture a pulse string continuously, you need the oscilloscope to have enough memory to capture the entire event. The required storage depth can be calculated by dividing the length of time to be captured by the sampling rate needed to accurately reproduce the signal.
Storage depth is closely related to sampling rate.The depth of storage you need depends on the total time span to be measured and the required time resolution.
Modern oscilloscopes allow users to select record lengths to optimize the details of some operations. Analysis of a very stable sinusoidal signal requires only 500 points of record length;But to parse a complex stream of digital data, you need a million points or more of record length.
Capturing the effective trigger of the signal in the right position can usually reduce the storage capacity of the oscilloscope.
Are the different oscilloscope probes interchangeable?
It's interchangeable as long as it's the same interface
Note, however, that the matching capacitance of the probe matches that of the oscilloscope
So maybe it needs to be adjusted
The other is impedance matching of the probe.The impedance matching part of the probe should be adjusted prior to use.Usually there is an adjustable capacitance at one end of the probe near the oscilloscope, and some probes are near
The probe also has an adjustable capacitance at one end.They are used to adjust the impedance matching of the oscilloscope probe.If the impedance does not match, the measured waveform will be distorted. The method of adjusting the impedance matching of oscilloscope probe is as follows: firstly, the input selection of oscilloscope is played on GND, and then the Y-axis displacement knob is adjusted to make the scan line appear in the middle of the oscilloscope. Check if the scan line is horizontal (i.e., if it coincides with the horizontal center line of the oscilloscope), if not, adjust the horizontal balance knob (usually the analog oscilloscope has this adjustment terminal, in the hole, need to use a screwdriver into the adjustment.Digital oscilloscope need not be adjusted).
Then, the input selection of the oscilloscope is connected to the dc coupling, and the oscilloscope probe is connected to the test signal output end of the oscilloscope (generally, the oscilloscope has this output terminal, usually the square wave signal of 1KHz), and then the scanning time knob is adjusted to make the waveform display for about 2 cycles. Adjust the Y-axis gain knob so that the peak - peak of the waveform is about 1/2 screen width.Then look at the top and bottom sides of the square wave to see if they are horizontal.If the phenomenon of overshoot and tilt occurs, it means that the matching capacitance on the probe needs to be adjusted.Adjust it with a small screwdriver until the waveform on both sides is level and there is no overshot.Of course, due to the quality of the oscilloscope probe, may not be adjusted completely without distortion effect, then can only be adjusted to the best effect.
