A few posts back someone described how to upgrade without disk/CDROM. You need to unpack the files to a specific directory and restart the oscilloscope.

Thank you for drawing my attention to this post, I missed this one.  :palm:

I did something similar from another directory and it was not working.  :--

By following the procedure it worked like a charm, the directory “update” was hidden.  :wtf:

After the 4.3 USB analyse was enabled and disappear after installation of 4.5.  :-DD

Is there RS232/SPI/I2C serial decode option for early Infiniums? Or any other options apart from USB testing voice control? All the literature I have seen has been pretty thin on that respect.

Here is the list  :-+

Pretty sure none of those work on the first generation Infiniiums.
"User must have Infiniium firmware revision A.05.30 or later"

That version number FW is for the 54830B/D series or later.

EDIT: In fact, other than voice control, the only SW options I know of are are runt triggering (standard on the 54835A and 54845A) and communication masks.

Has anybody ever played with voice control? I've never seen that in action...

My scope is now 100% OK and update to the latest version.  :-+

Now the probe problem, I have 1 new 1161A supplied with the scope, maybe I’ll try to get another one on a “decent” price but need to come from Europe since shipping and duty make it not affordable in comparison to the investment of the scope.  |O

I will maybe buy 2 or 4 200mhz probes from Hantek, they are not expensive.  ???

Now why having a 1.5ghz scope and not having the appropriate probes?  :phew:

They are too expensive, 500-800€ and more + shipping cost + duty’s for 1 probe!  |O

Why not build one like this one : https://elektrotanya.com/files/forum/2009/10/e04a036.pdf  :-BROKE

But put it in an aluminium tube or buy one like this one : http://www.benl.ebay.be/itm/RF-Active-Probe-0-1-1500-MHz-1-5-GHz-analyzer-oscilloscope/332253695460?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649

It should be possible to get power from the autoprobe, I could manage to build a BNC connector with a pin to get the right voltage needed for this kind of probe.  :bullshit:

Anybody experience in this area?
