Hello,

I don't think this group can produce such profanity that I'd be
worried if my kid got to read it.

If they're old enough for electronics, they're old enough to know
about and glance over the "adult" expressions, and if they can't handle it, then

someone is failing at parenting.

Sadly, accepting that requires taking personal responsibility...which does not go along well with being a crybaby in the first place.

The issue here, is, that so far, conservatives have always walked away, hoping that the person will grow up. Sadly, practical experience shows that this is not the case.


IMHO, there are two possible outcomes. Either a) we stop giving a quarter, or b) other countries do it for us.

892X Cal file request ...RF I/O

 

Looking for the Cal fie for an RF I/O assembly .

Need to update the calibration factors for a repaired RF I/O and it looks like the easiest way is to just update an existing cal file with the needed values.

I have actually corrected the values on the EEPROM but the checksum? for that area is no off? and not sure what hash or checksum routine was used? ...looks like its 16 bits at the start of the array.



May be worthwhile to actually keep a collection of those files for the different assembly types as well

?

Thanks

Re: E4418B power meter clearing Ram battery failed

Hi Paul,

I measured a working E4418B here.? The battery Voltage on mine is 2.8948V with J1 in and 2.8960V with J1 out.? The current measured across J1 is about 42 microAmperes.? This is without AC power connected.

Hi Paul,

First, measure the current draw on the battery when there the E4418B is disconnected from AC power.? You can do this by pulling the jumper (J1) and measuring the current across the jumper pins.?? If the current is too high (I can measure a good one later today), I would check C78 (10 microFarad, 10V cap) or diode CR2.?

Hey, be careful here, this is very subjective, and your assertion is
wrong.

Case in point: I use "the F word" all the time, and it's not for
"shock effect", it's just a part of my normal, everyday vocabulary. I'm
not a devil worshipper, an axe murderer, a drug addict, a child rapist,
or an uneducated thug...I just say "F***" a lot. And I'm no outlier
here: Most people I know are exactly the same way. And I keep a very
high signal/noise ratio amongst my social contacts; they are all
technical people, and nearly all engineers of one sort or another.

And since you mentioned mothers, about mine: My mother is a noted AP
journalist, a published author, and was (before retirement) a respected
corporate CEO. She said to me last night on the phone that she was
"F***ING SCARED" of this hurricane. (she's in Florida)

With (at least some) respect, people who get all uppity because they
[gasp] HEARD A WORD really need to calm down and get a grip. If that
sort of thing is really the worst thing that you face over the course of
a day, I'd gladly swap lives.

Seriously. I don't mean this as crappy as it sounds; I don't hate
these people. I really do feel badly for people who are so sensitive
and touchy that their minds are thrown into a tailspin because someone
else said a word. What happens when real problems pop up in life? Some
nutjob Republican bumpkin with an AR-15 goes berzerk, your house catches
on fire, a friend gets cancer, or something like that? If hearing a
word makes a person so upset, I'd not want to be anywhere near that
person in the face of real adversity.

Don't sweat words. Worry about what matters in life. Please think
about this.

And how do you know what that person would say in front of their mother or their kids?

I too agree that there is a limit, but I don't know what that limit is and I'd rather have social pressure than outright banning. Ultimately, if I don't like the way someone speaks, I'm going to block them. If everyone in that group is like that, then I can just leave.

Hello,

I had the same issue long time ago. It was a faulty RF amplifier stage. As far as I can remember schematics are in the net and the amplifier was something like ATF 53142 or so.?

I soldered thin coax onto the board in order to pickup the signal stage by stage and find the fault.

?Cheers,

Hi.

Thanks for that, and yes I suspect it's just an internal amplification issue.

Yes, I also found some schematics in the past, but also note that ArtekManuals have the full service manual + clip.

??? ????? and just put 8714B in the search box.

Need to find some space to do stuff like this, as those modules with the covers removed (for access) are rather vulnerable to mechanical damage.

Re: HP 54542A

 

Hi,

just to confirm: Yes, the battery is a CR17450SE and I replaced
it on both my scopes 2013 and 2017 which is quite some work as
one has to remove the mainboard to do so.

The replacement was priced EUR30 and compared to the work in-
volved, I was OK with it. Be aware: (1) If the battery is
really empty, the scope even fails to start. (2) After re-
placing the battery you will have to do a calibration
which is automatic and guided by the firmware.

From the datasheet of this battery (i.e. no recharge!!):
250mAh, 3V, max discharge 9mA continuous 150mA pulsed.

Best wishes,

Erik.

If I remember correctly the battery is a CR17450 it?s a 2/3 A.A. 3 volts with two pins on the
positive and one pin on the negative. I have seen them on eBay but they are very Expensive and the
shipping is costly too so I use a AA 3.6 volt with long leads at both ends so I sleeved the
negative lead and solder it to the board it?s longer by a few mm but there is plenty of room.
The battery goes to two Dallas DS1210 each go to two CXK581000AM static cmos ram they hold the
calibration data and the switch settings when you turn it off. The Dallas chip is good to 4 volts
so ok with 3.7/3.6 volts. There are other batteries that can be made to fit. I alway change the
battery on any equipment I buy as you don?t know when the battery was installed these battery can
just fall below the cmos ram minimum voltage after many years of use. Has anyone got the CLIP for
these series of scopes if so I would like a copy.
