How to use digital oscilloscope to distinguish analog bandwidth from digital real - time bandwidth?
Bandwidth is one vital index of oscilloscope. Bandwidth of analog oscilloscope is one certain value, however, bandwidth of digital oscilloscope has two kinds, analog bandwidth and digital real-time bandwidth. Digital oscilloscope to repeating the signal in a sequential sampling and random sampling technology can achieve the maximum bandwidth of the oscilloscope digital real-time bandwidth, real-time digital bandwidth and the highest frequency and digital waveform reconstruction technology related factor K = (digital real-time bandwidth digital highest rate/K), generally not directly given as an indicator. It can be seen from the definition of the two kinds of bandwidths that the analog bandwidths are only suitable for the measurement of repeated periodic signals, while the digital real-time bandwidths are suitable for the measurement of repeated signals and single signals at the same time.
The manufacturer claims the bandwidth of oscilloscope can achieve how many megabytes, it is analog bandwidth actually, digital real time bandwidth is below this value. For example, if the bandwidth of an oscilloscope is 500MHz, it actually means that its analog bandwidth is 500MHz, while the highest digital real-time bandwidth can only reach 400MHz, which is much lower than the analog bandwidth. Therefore, when measuring a single signal, it is necessary to refer to the digital real-time bandwidth of the digital oscilloscope, otherwise it will bring unexpected errors to the measurement.
Causes of damage to oscilloscope current probe
The reasons for the damage of the current probe, the methods for preventing the damage and the instructions for using the current probe can be summarized as follows:
Circuit board damage caused by plugging current probe after current amplifier is turned on.
Protection against damage: - do not plug or unplug the current probe while it is still active.
Magnetic ring is fragile material, drop or use too hard when it is easy to damage. Damaged/damaged magnetic rings will result in inaccurate or no longer detectable current.
How to prevent damage and use: - avoid dropping or using too hard.
Magnetic ring coil is thin, over current will cause coil burn out.
Prevent damage method: - avoid the load flow when using.
The current clamp is not aligned, and cracks will make the test inaccurate or unable to measure the current. Be careful how you push the clip.
Method to prevent damage: - when using the current clamp to align. Be careful and be careful when pushing the clip.
The cable can be easily damaged if it is pulled too hard or twisted.
Prevention of damage: - do not use the cable too hard to pull, twist, etc.
