The analog front end of oscilloscope is the key to determine the bandwidth
The key to determine the bandwidth is the analog front end of the oscilloscope, including attenuator, amplifier and related circuits. It is the gate through which the measured signal enters the oscilloscope. The bandwidth of the test signal of the oscilloscope is determined by the bandwidth of the analog front end in many cases, which directly affects the background noise and range of the oscilloscope. The design of analog front end takes up more than half of the work in the hardware design of oscilloscope, and determines the hardware performance of oscilloscope to a large extent.
For the analog front end, the main performance indexes affecting the oscilloscope include:
●analog bandwidth, including the amplitude-frequency response characteristics of the measured signal, in the time domain as rise time index and overshoot performance index;
● dynamic range of input signal amplitude (range from minimum vertical sensitivity to maximum vertical sensitivity for non-digital processing);
● initial error characteristics and temperature drift characteristics of dc gain accuracy and offset accuracy;
● input impedance characteristics (parasitic capacitance of resistance in parallel) influence on the circuit under test with or without a probe.
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.
