Sampling Oscilloscope
Anyone knows what's it used for?
Well, I know it can perform Time Domain Reflectometry, but I don't know where TDR is necessary. Mother board, audio card or video card design or testing?
Thanks in advance.
mentor pads on virtual pc
I never tried but it is possible.
If you have run both installation on the same SDD_HOME Directory the configurator file keeps tracks of all the versions. You have to launch it (it shuold be in SDD_ROOT\win32\configurator.exe) and then select the version you want to...
how to calculate battery life
Keep in mind that the nominal battery capacity is only reached when you discharge it with a constant current. Your system power consumpion will be strongly variable, so charge effectively available could be as low as 60% of the nominal charge or worse.

copper resistivity inch
While studying this high-speed signal integrity book by Thierauf I found this resistivity table that looks wrong:
https://books.google.com/books?id=SbuUX63oTIYC&printsec=frontcover&dq=high-speed+signal+integrity#PPA18,M1
The firs column (Ω-meter column) looks right but...
protect pcb
I need to place Wireless Sensor Network PCBs in outside environment. It won't be directly esposed to wind or rain but it needs to relaiably work for montsh in harsh conditions of temperature and humidity.
I don't know if there's some insulating spray or paint that is commonly used...
Proportionality between Vin nad Vout wouldn't be possible without a connection. The equivalent circuit just doesn't make it evident, but the voltage controlled voltage genarator (A*Vin) means some kind of electrical connection exists.
Re: metor graphics
PADS 2007 doesn't make that.
In PADS Logic you draw the schematic, in PADS Layout you define the layout and in PADS Router you make the routing.
HFSS by Ansoft does it.
I suppose soldering them out and measure them is not an option since if they're burnt out their value cuold be altered from the original.
So, yes, it is impossible to guess without additional infos.
What amplifier is it? See if you can find a manual or a schematic on the net. Or try to draw...
pastemask soldermask pcb
Ok. I think that for a standard size pad a 1:1 pastemak/pad and soldermask/pad ratio should fit as for the other packages in the OrCAD libs. Upon generating the gerber files I'll set it if needed according to my manufacturer's capability.
pastemask
Hi everybody,
I'm switching from Mentor PADS 2007.2 to OrCAD. I'm trying to build my first padstack in OrCAD but I don't know how much I have to oversize the soldermask and pastemask with respect to the pad size, since Mentor PADS does it automatically. Does anyone have any...
