Re: [HP-Agilent-Keysight-equipment] OT: Looking for a Pentium M765 (or maybe M780 - not sure it that will work)

 

That's why I linked you to a card that slots into a PCI slot and
provides you with a PC/104+ connector.

At which point the sky's the limit with inexpensive, powerful motherboards.

Re: 7904A compress sweep

Harvey White
 

I would guess that the horizontal drivers are bottoming (or topping) out.  This suggests a power supply voltage is off.  That it suddenly goes "good" then back again suggests that the *effective* power supply to the horizontal (or vertical, too) amp is changing.

I'd measure the power supply voltages both on the deflection driver boards and the supply itself.  Problems could be bad connections, a filter capacitor acting up, an odd filter resistor (if any).

It could be just as easy as a transistor (in the input circuitry) with an intermittent contact.  I'd be checking the static voltages with the intensity turned down to zero and no sweep.

I need some advice on where to start looking to track down a compressed sweep issue on a 7904A I was given.

The sweep is compressed by about one division on each end and it does not matter what plugins or channel combinations are used. The readout seems slightly compressed as well.

Very rarely it will suddenly appear normal width and readout seems to slightly expand but then seems to revert shortly after.

Its a very nice scope in otherwise excellent condition.

AFAIK both the M765 and M780 are socket 478 which is what this board has.

If you're going to replace the CPU only, make sure you get the correct socket-type for the replacement CPU.

The CPUs in question only come in one socket type!

These are not just idle questions. My wife and I are seriously considering visiting some family in the Portland area, but unfortunately, in August, not after Sept. 1. On the other hand, that's a good thing. I should not be allowed in surplus stores, flea markets, or junk yards.

Re: Members in Germany, Brussels, and the Netherlands affected by the floods

 

There is no way to avoid progressing global warming unless the largest
single polluters are brought to justice - including jail time for
everyone involved. This means the full executive and top engineering
rosters of the largest corporations. Call me a socialist, but there's
no way this correction will happen in a fully free market. The mere
notion of free markets requires ignoring issues that happen not on the
market itself - such as pollution, global warming, etc.

Climate change? nah that's just a myth. Yeah right. And its only going to get worse in the next 5-10 years regardless if anything serious is done about it today. Which it is not.
That wheel is already spun up pretty good and it can't just be stopped cold. I can sometimes see 3-4 planes crossing path in the sky leaving contrails in the space of just 15-30 minutes.
Absolute madness how we are destroying our own environment.
