Ahh yes that looks like it could be useful. Since I don't really have many requirements other than generating a clean clock signal overkill is probably fine. I guess will probably just buy a few components and try to see what works best.

I need to create a 10 MHz square wave clock signal which gets terminated into a 50 ohm resistor for use by a waveform generator. The specifications for the waveform generator suggest a 12 to 14 dBm power level for the input clock. ie. a power level of ~16-25mW. So I've been looking to...

I've adjusted probably every setting on my oscilloscope and triggered on rising and falling edges and I have also tried it with the 50 ohm terminations removed. Also it is just a simple sma connection from the waveform generator to the oscilloscope with the terminations connected with a bnc...

I'm using coaxial/sma connectors and the terminations are coaxial terminations. I'll check out a square wave tomorrow but if jumping due to the trigger is only supposed to be around 10 ps then it seems like it probably is the waveform generator. Which at least narrows it down. There are some...

I'm using an arbitrary waveform generator that is generating a 1 MHz ramp waveform. I'm triggering on a marker sent out by the waveform generator which is tied to the same memory location as the start of the waveform. So although there is supposed to be a small latency (1-3ns) between the...

The assumption that for all possible integers n, n!>[(n+1)/2]^n is violated by your counter example, so that demonstrates that your assumption is false. You have not checked all possible values of n so it says nothing about any of those values. Your assumption being false says nothing about...

Try defining each vector (a_1, a_2, a_3), (b_1, b_2, b_3), (c_1, c_2, c_3) and then using the defintion of the cross product in each case.

Thanks, I can solve the rest of it pretty easily now. I think I was just over thinking which springs were pulling where.

Homework Statement 4 springs with a mass on each end are connected in series as below: | | | | m1 | | | | m2 | | | | m3 | | | | m4 All the masses are mass m, the length of each spring is 1, and the spring constant is k, find the extension of each spring...

Well I went into the lab, and now that I have a better understanding of how the ground connections work I found several other ground connections on the other end of the protoboard so it became pretty straight forward to set up several things in parallel with the coaxial cables. I knew it had to...

Thanks for your help, I'm going to stop by the lab tomorrow and play around with the circuit so I'll post after that.

Yeah that makes sense, in that case would the second drawing I made with the three ground connections represent the circuit you're talking about?

I think we are supposed to construct the circuit using the BNC connectors, and our TA suggested we connect the voltmeter in that fashion so It can be done. I don't even think we were provided with cables to form a direct connection across the resistor with the voltmeter. I may be able to find...

On the diagram you drew I could construct the circuit fine because there are clear positive and negative terminals for each item, but I can't see those on the protoboard I'm using.

No it doesn't. Here is a picture of the actual protoboard, sorry it isn't closer
