How to deal with the damage of oscilloscope bandwidth and signal fidelity?
High-speed signal acquisition and processing requires a series of connection and switching at the front end of oscilloscope.
The signal is transmitted from the DUT to the oscilloscope, via coaxial cable to the PCB, through the ball gate array (BGA) package, and then to the first integrated circuit (IC) for analog amplification or attenuation. The signal output package is then delivered to the PCB and sent to the next package containing the track and hold (T/H) IC. Only after this string of connections is the signal ready for sampling, analog-to-digital conversion, and storage. Unfortunately, this series of connections and switches and subsequent iterations degrade the signal before sampling, thereby compromising oscilloscope bandwidth and signal fidelity.
To overcome these problems, teck USES custom designed, highly integrated front-end multi-chip modules (MCM) in the DPO/ dsa7000d series oscilloscopes. MCM incorporates a variety of front-end acquisition and processing components, including coaxial cable input connectors, preamplifiers, tracking and holding chips, and terminal resistors, into one package, so that the PCB is never touched until the high-speed signal is sampled.
The custom front MCM package for the DPO/ dsa7000d series brings together a large number of previously dispersed components, including
● Two preamplifier chips;
● An 8-way tracking and holding (T/H) chip with analog filter;
● High performance 100GHz bandwidth connector
● Flexible connector to PCB.
Because it is a self-contained module, MCM reduces the number of connections through which signals flow and the number of possible sources of error. The user will not have multiple signal jumps through the single chip package and PCB layer, which will degrade the signal fidelity and oscilloscope bandwidth before sampling. Using high-performance cables, high-speed signals are transmitted directly from oscilloscope inputs to MCM and internal integrated circuits. IBM's 8HP technology is a 130-nanometer (nm)SiGe bipolar complementary metal oxide semiconductor (BiCMOS) process that performs twice as well as previous generation processes.
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.
