Re: HP 5343A SMA ¡°Insert¡±

 

Brad,

The 26.5 GHz input N connector connects directly to the input of the sampler assembly U1. The 500 MHz BNC input is a fused connector of which the body mounts directly to a printed circuit board on the rear of the front panel. For an illustration of the BNC assembly see page 6-3 of the service manual P/N 05343-90007

Jim,

I screwed up by calling out page 118 in the service manual in my last message. I had a HP parts catalog open at the time and noted that page instead. The actual page is 6-35 listing the only SMA connector found relating to the sampler driver assembly.

He's been told to match numbers and if they aren't exact, then it won't work.? That's it, thanks.

Sad...

I wonder how this short circuit you encountered would explain what would happen having a home with a 48,000 watt power service feeder that only has a 60 watt bulb turned on inside.


Re: HP 5343A SMA ¡°Insert¡±

 

Jim,

I looked through the manual but could not find but only one SMA connector reference (P/N 1250-1353) in the part list in manual P/N 05343-90007 page 118. There are other references to SMBs. I¡¯m wondering if this item was assembled as a cable assembly of which plenty of them are listed in the parts list.

This part number item is also found in the 5342 instrument.

I don¡¯t have time at the moment to open one of the 5343¡¯s in the lab.

Re: HP 5343A SMA ¡°Insert¡±

 

I'm told this is a coupling capacitor and is found on the input of the 5343A.


Anyone able to do GC or GC-MS on Hp ThinkJet Black ink ( for the Hp ThinkJet 2225 printer; Hp 9226a Or Hp 51604a ink cartridges ) ?

HP8568B HT BASIC and GPIB NI

 

I am trying to figure how to set HT Basic to interact with a National gpib interface and with mu 8568B.
HT basic is installed, the NI interface is seen by windows, but i don't understand how to see the instrument by HT Basic.
Any advice?


Re: OT: a tale of two chargers.

 

Oh, and I also once observed one of those same Best Buy and Circuit City geniuses trying to sell a little old lady a television set circa 1987.? She was commenting that the picture really didn't look quite right to her.? Explaining that the television had multiple picture operating modes, he reached behind it, turning the vertical hold control just enough so that it would unlock, slowly roll up the sync bar and picture, then snap it back in on the next lock pulse, asking the lady to tell him when she saw one that she liked.

Re: HP 5343A SMA ¡°Insert¡±

 

Let me see if I can find a schematic and/or other documentation for the 5343A.? I have a working 5343A in my microwave rack as well.? Would be interesting to take it apart!? ?Thanks for the inspiration!? ? Jim Ford, Laguna Hills, California, USA?

Re: hp3456A auto zero

 

OTOH, if you are working with high impedance/low current circuits and try to use a regular DMM with say, 100 megohm input impedance, you may think you're violating Kirchhoff's current law.? Been there, done that.? Turns out, the bias current into or out of the DMM is on the order of the currents flowing in your circuit.? In which case you will need a 3456A or a 33401A in hi-Z mode to get accurate measurements.? And then you will see the voltage drift with the probes open circuit until you short them together.? Good luck and have fun!? ? ?Jim Ford, Laguna Hills, California, USA?

On some meters and ranges with definite input R, you can have zero, but the 3456A is a lab grade unit with virtually infinite input R in its native range, so it all comes down to bias current, which will not be zero. This can be a very confusing aspect of DMM input specs, until you understand what's going on. The shunt resistance of any input fixed resistance or range attenuators outside the native range simply hides the fact that the bias current is there.

Re: HP8595E - SYTF

 

¿ªÔÆÌåÓý

Ed,? totally agree.
The problem is that I am out of ideas?about how to increase the diameter of this tiny rod from 0.5 to 0.75mm while maintaining good cylindrical symmetry, uniformity of diameter and a surface hard and smooth enough to slide it?into its original location
I will think about it, thanks

Oggetto: Re: [HP-Agilent-Keysight-equipment] HP8595E - SYTF

It may cause some grief, but I think you'd be better off keeping this other YIG sphere attached to its original mount, and adapting the mount to the situation. After all, this is still all experimental, so take the simpler path until you get a better idea of the situation. If it looks promising, then you can invest more effort to redo the YIG onto the original rod. If you're already at this point, then go for it, and good luck.

Agilent 16700B / 702B correlation with DSO9000 Infiniium scopes

 

Hi,
Did anyone try to link a 16700B or 16702B LA to an Infiniium 9000 series DSO or MSO scope? Due to their different generation this has not been documented. But as the suggested Infiniium 54800 are the ancestor of the 9000, maybe there will still remain a bit of code in the latter to correlate both via ethernet +/- the E5850A correlation fixture?
Best,
Christian

Re: HP 5343A SMA ¡°Insert¡±

 

On an input connection, it's likely a series capacitor for AC coupling, or a protection fuse that's blown.?
?
If not a fuse or series capacitor, I'd guess a modular attenuator element, or less likely, a PIN limiter. Just measure the R or semiconductor character between the ends and to ground to get the answer.
?
The other thing is that you don't know if it's burned out, so more complicated.

Re: HP 5343A SMA ¡°Insert¡±

Is it by chance a protected input? A fuse of some sort?
