Can pulse generators output 100mA?

AI Thread Summary
The output current of a pulse generator depends on its specifications, which are often not detailed in datasheets. A 5V pulse with a 50-ohm output impedance theoretically allows for 100mA output, but this is contingent on the pulse duration being sufficiently long. If the load is 1 ohm, one could expect around 100mA, assuming the pulse generator is designed for that output. To verify the output impedance, one should measure the open circuit pulse amplitude and then apply a 50-ohm load, observing the voltage drop. Understanding the specific model and manufacturer of the pulse generator is crucial for accurate assessment.

If I have a pulse generator what is the current it can output? It doesn't say in the datasheets

IF I have a 5V pulse and 50ohm output impedence am I supposed to believe it outputs 100mA?

And then if my load is 1ohm I should get something near 100mA through it?

That depends on your pulse generator.

IF I have a 5V pulse and 50ohm output impedence am I supposed to believe it outputs 100mA?

And then if my load is 1ohm I should get something near 100mA through it?
If the pulse is not too short, I would expect this to work.
 
Who is the manufacturer and what is the model number of your pulse generator ?
 
100ns pulse
 
Nobody can answer that question without a data sheet. If this is an instrument, then it may have a 50 ohm output impedance, so analyze as if there were a 50 ohm resistor in series. Or it may have settings for the output impedance, or a low impedance mode. I expect 50 ohms.

To test it, measure the open circuit pulse amplitude, then apply a 50 ohm load. The change in voltage will tell you the output impedance. It will go to 1/2 the voltage if it is a 50 ohm generator.
 
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
