sony meter bandwith
i picked up this portable oscope at a fles market long,long ago.(model type 323)
the question is the scope only goes up to 5microsec on the time knob.
to find the bandwith is it 1/max freq,in this case 1/5 micros?
and,is this good enough for monitor work?... -

Re: best cheap/free scores 1.1
oh man!!!
you mean 802.11b its an older technology?
and i thought i had the top of the line with my 5 dbi alfa usb adapter.(what can you expect from a 64 yr old man?)
it works ok for me ,but what do you recommend i upgrade to?
will it be faster,stronger?or what its different with the newer technology?
i am going home to mcallen texas and i probably can get a better equipment.Leave a comment:

Re: 7c9l17-18l regulator?

Re: 7c9l17-18l regulator?
thank you t30m31,

i am going to go over the squematic and try to find what and how was this ckt affected by the caps.

Re: VIEWSONIC VG2030wm goes off after a while
thank you bud,
i will try that next time.
i am going to call this monitor FIXED.
IT WAS ON ALL NIGHT ,AND IT WAS STILL GOING STRONG AS OF 10:40 AM TODAY.
after reading on the different posts ,threads from you and other valuable info from the rest of the guys that pitched in,i used the shotgun approach and replaced all the small 10mf/16v caps,one 47mf/16v cap(which i think it was the culper) on the logic/main board.
they were showing some ac voltages like 1.6 ac v on the 3.3 test point ,and .139 acv...Leave a comment:
