what is post & jig test for hardware
Hi,
i want to build a testing jig for a multy output power supply,
that checks correct output voltages,ripple etc.
the result should be send automatically to a PC.
Did anyone ever build such a jig?
any ideas?software?
Thanks,
BULL
thanks all for your help.
i see i have a long way infront of me...
few plls,few quartz,few spacer & screws,few coax...
not to talk about the amount of the caps & inducators...
thanks for giving me a these clues ,ill check them...
again thanks for your help...
bull
also,..yes i use coax inside the box...
i use mcx coax cables (very short)..they carry if 7 rf signals...
what makes the coax cables suspecious...?
how can i protect them?
what kind of coax should i look for...?
thanks,guys..for your help..
bull
thanks all for your help..but..:
to be more specific,the box is located on the roof.any kind of nature "knocking" ,like rain,wind etc,causes the problem.
its not a mechnical problem (connector etc...)...
i also suspected on the quartz & osciltors. is there any way to protect them or the...
does someone know,how to overcome microphonic disturbances in electronics..?for example:
an elektronic unit mounted in a closed metal box.when knoking on the box,it causes ber...,
what electronic component can be sensitive to this phenomenon..?how one can overcome this behaviour..?
pls help

hi,
as wrriten on the subject,i have a dc\dc that supplies -90V,and i need to
supply also +5V\2mA,on the same ground.
i thought on linear regulator,to save space & money...but how should i connect the ground between the -90 and the +5V...? (THEY MUST BE ON THE SAME GROUND !!!)...?
THANKS...

hi,
where can i find current limit circuits (for 50ma current)example to build from scratch,
and is there any ICs that do that as a singke solution?
thanks for any help...

Hi,
i need to design a U interface ISDN channel (LT).
does someone know what is the power that should be supplied to the remote end (NT1),in case of power failuire acording to the spec....?
thanks...

Hi,i need to design a programmable switch ,for 20DC Amps,to simulate
A dc\dc power supply MicroInteruption problem. and to check the system withstand.
any idea....?
thanks...
