Hi All, I have a Pocket Technologies LogicScope 136. It is a small 2 channel LED logic analyzer. The probes for it have a tip that threads in. As shown in the picture, the tip has a threaded base that goes in the probe. The probe is not easily replaceable, the connection from the probe head to the cable is threaded. There are no ide
Which opamp to be used for differential oscilloscope probe??? Should I use fully differential opamp??
If there's no separate specification, you can expect that the oscilloscope has 1 GHz bandwidth with both termination settings. But you should consider that it's effectively impossible to achieve 1 GHz bandwidth with 14 pF load. You'll need about 10 ohm source impedance. Passive 10:1 oscilloscope probes for the 1 MOhm input are available with (...)
You are asking about high voltage oscilloscope probes respectively inbuilt voltage dividers in your instrument, not "cables". You should give a rough idea about the intended measurement bandwidth respectively signal rise time. Also the acceptable pulser output load by the measurement circuit. Passive oscilloscope probes, (...)
I am testing a high frequency inverter PCB running at 100 KHz. When I probe any node, for example DC Link voltage, load current etc. there is a lot of noise superimposed on the actual signal. The noise is simply switching spikes picked up by the probes but not actually present. The on-board ADC seems to read clean signals, but the scope displays e
Hello friends I am trying to measure high speed USB signals with an oscilloscope. The signals are differential and run at 480Mb The impedance of the tracks is 90 Ohm (Zdiff) Problem: I have 4 proto boards (10 layer) rev 1 and all working on USB2 high speed 100% I now have a heap of new new proto boards (same design different board maker
For buying a 2nd hand old tektronix scope without probes, I have the following questions: (1) Can any probes be used with the scope or specifically tektronix probes? (2) Can any model of passive probes be used with a scope? If so, I shall get the cheapest passive probes with 100MHz band width. Possibly 2nd (...)
Hi, Do i need special connectors to view output on oscilloscope or i can just use the usual probes and connect them to headphone-out or line out of DSK (C6713)?
probes 101 pls read The 9Meg R in the probe is used with the trim cap to match the cable capacitance and input capacitance of scope with 1M to get a 1/(1+9) attenuation or 1/10th the signal with a flatter response from 10 to 100MHz.
The oscilloscope only has 9 bits of vertical resolution. That is 512 levels. To measure a voltage of .0001V, your maximum voltage (voltage range) would be at best .0512V, far below the 20V range you are measuring.
Two channel oscilloscopes usually can measure differentially by using two probes and one channel inverted.
Without the common ground you will have to use a capacitor voltage divider May be appropriate in special cases, but hardly a general solution, I think. A differential voltage divider (resistive or compensated RC), as it's used in differential oscilloscope probes should be widely applicable.
I have got an x10 single ended probe.Can I use this probe to apply the differential signal to the oscilloscope...? Yes, but you need two of it. Compensation adjustment of both probes must match well.
The oscilloscope measures the voltage betwen it's ground clip and probe regardless of the rest of the circuitry. Think of it as being like normal test meter probes, wherever you put them, the meter measures the voltage across those points. The isolation transformer is there because on most (if not all) oscilloscopes, the ground clip is (...)
If ground to neutral isolation is required and a measurement transformer isn't an option, symmetrical voltage dividers and differential amplifiers are probably the next best variant, as used in oscilloscope high voltage differential probes.
Evening gents, I recently just got my hands on a 20MHz Kenwood CS-4025 oscilloscope, but the problem is there are no probes. Is there any particular type of probes I should be looking for to use with this scope? If so, what kind? Also, where can I buy said probes? Thanks again!
So you need to refer to the other options. Shunt measurement will probably require a fast differential amplifier to pick up the voltage. Current transformer can be easily made: A small, high ?r ferrite torroid of 5 to 10 mm diameter. 10 to 50 turns secondary winding, terminated with a low ohmic resistor or 50 ohm oscilloscope input.
In my understanding, you are reporting problems of unsuitable signal probing. To probe low level signals with little interferences, regular oscilloscope probes are more or less inappropriatw. You should think about coaxial jacks (BNC or smaller) or coaxial cables directly soldered to your circuit. There may be still problems achieving a clean p
Hi ejunear, I found this circuit on the Im not sure if it represents all kinds of scopemetters probes. It seems that, there are no restrictions regarding components which could be polarized. Then, once probe can work measuring sign
The probe specification is incomplete, because it misses exact values for accepted oscilloscope input capacitance range. This may be due to the fact that the probes are primarly offered as acessory for Pico USB scopes. Most likely it works with all industry standard oscilloscopes, in case of doubt you can compare with PicoScope impedance (...)
