Re: Hp16702a Reignite freez

 

Okay, it's really silly. I dealt with the problem in a fairly simple way - the battery was dead and needed to be replaced.
Without a battery, or with a 0V battery, it is impossible to perform the Reignite procedure; the device will throw errors and notes. It previously seemed to me that the battery is solely responsible for the clock, and that when connected to 230V, the power supply provides the RAM with the necessary voltage to save data, as in modern PCs, but this is not so.
By the way, to connect a CD-ROM it is not necessary to have an adapter from one scsi connector to another, or to change the cable. It is enough to disconnect connector J10 and connect it to the CD-ROM , placing a jumper on it to turn on the terminator.?
Power for the CD-ROM can be taken from the MOLEX HDD; its design allows you to continue the line with new wires.
It is also useful information that DVD-ROM can be used for this procedure, because any DVD is also a CD.
Here is the I used, it is tested and works.
Re: Testing Scope Probes

 

I managed to write some code to control the sig gen and the 1GHz Tek scope using the classic levelling system described a few posts ago.

I tested the 50R input of the scope first and it was flat to within about 0.2dB up to 500MHz. This doesn't prove very much because this scope has a different path for the 50R input, but it was still interesting to do it.
I then swapped to the 1Meg input and compensated the 10073C probe using the usual procedure and then tested it for the frequency response when fed with a 50R source and a 50R termination. This is the Tektronix method.

See below for the result. It looks quite similar to the simulation I did earlier. The response is 3.5dB down at 500MHz. I was expecting it to show a bit more droop than this, but it appears to show the correct response when the system is loaded by the probe.
Re: HP 8568A YTO UNLOCK repair

 

That is what i've done so far, but i'm still unsure of my conclusion.

That's why asking if someone ever had the same symptoms. Because i want to buy a new YTO and i want to be sure that it is the YTO given the fairly expensive price of that part.

Re: HP8484A failure modes

 

That's a good point. The schematic only shows a single diode in the probe.? But I did also find a figure for the bulkhead output when fed 10uW and mine is low, so I suspect it's an ESD type failure of the diode.?

Please understand the way they do it over there!!

Even simpler things have similar . multiple outlets- at ?ec alliexprex.It seems they do not care as we do do.

But I and several others in Canada-UK-Australia,Denmark have received good well packaged MXA``?s from---THEM¡­.-I have receive 4!!!

So bogus?? Your choice.

Yes Carsten the same items are listed with multiple sellers and understand it looks a bit bogus.

However it looks like mobile phone manufacturers are getting rid of their old test kit to anyonyone and various 3rd parties are selling them on.

They've probably got 100's if not 1000's of them.

Some seem to have no idea and eventually found a seller via the .com site rather than the .co.uk site with a better price and who was willing to communicate, show pictures of the options etc.

The adverts are poor and cut and pasted and do say 'Brand new', XP system etc as the sellers dont know what they are selling.

You may be able to get a $1200 one with all the options if you look hard enough. I paid a bit more but as a run a business so it hurts less!!

Will report back when it arrives.

Regards to all

p.s. Oh just to answer the other question re 'Is it any better than a 8566B'

Yes, very much so as it's way more than a Swept Spec Ani.

Yes how astute of you as was I and hence why I had to message the seller 20+ times!

It is the whole thing with all the options listed.

Re: N9020A

Yes, take care, for instance if you read the (very) small print much further down on the listing from of the 'other sellers' with the title:

1pc for used Keysight N9020A MXA signal 3.6G spectrum analyzer (selling at 1997.14 GBP)

It actually says:

*?100% Brand New
* We apply comprehensive quality check and testing before dispatching
* This item could be used to replace touch panel?which is?broken, damaged, cracked or unusable.

Bullet point 3 could be a cut'n'paste error of course, but? note the '1pc for' at the start of the title, it does make me wonder if you might end up with just a new touchscreen for your two grand??

I'd recommend you ask the seller what they are actually selling.

Hi

Jeremy

I fully understand your point¡ªbut after been buying from them some years I have no problem with it---even returned an faulty ?MXA without extra cost¡­and got a new one.

They actually sell well performing MXA`s,not just xp op sys.

But You are right-they seem to very be relaxed with pictures of the units they want to sell¡­. So ask for specific pictures of the goods you want to buy¡­And multiple accounts?¡ªyes that¡¯s right!dont know exactly why.

But bottom end ¨C I still deal with them-no problem for me.

Hardy

Re: N9020A

 

Peter
It depends on what you want....but the N9020A are part of the X-series known to be a first class series--the units sold at e,,,, are MXA N9020A 506-3.6Ghz option B25.....and some with several options as Noise Figure,,-Phase-Noise,,Demod AM-FM,PM-Display Enhancement(Full sweep spectrogram)...all sorts digital demod------and pre-installed VSA 89600 software with no license(ver.14.02)This software have a inbuilt front-end converter function...and much more.So Peterif you consider this- you can use your HP856x as a front-end if you need to go very high-calibrated..
So yes its at least a very competent SA,... --its one of the best today-----!

Thanks Hardy, ah, I mistakingly thought it was a SW option so no chance of RTSA then, no worries.

Many thanks for the info.
