Objet?: [HP-Agilent-Keysight-equipment] 8560E: Restoring THRU calibration from a controller

?

I am working with an 8560E spectrum analyzer with tracking generator.

?

I understand the tracking generator calibration when doing e..g a THRU calibration is stored in trace B.

?

I am able to save trace B after such a calibration to a controller from an 8560E.? ?Data looks like what is on the screen for trace B.

?

I can write trace B back to the instrument -- and it looks fine.


But I cannot get normalization to turn on.? ?I've tried a number of sequences, such as:

?

? ? sa.preset()
? ? sa.start_frequency = band.start_frequency
? ? sa.stop_frequency = band.stop_frequency
? ? sa.write_trace(calibration, which='B')
? ? sa.normalize = True
? ? sa.sweep_coupling = "SR"
? ? sa.source_power = True

?

?

(The parameters are the same as when the calibration was done.)

?

This results is Err 902? (Bad Norm) and Err 903 (A >? DLMT).? ?

?

Does anyone know if this is even possible?

?

(I do understand that I can store the thru calibration into a state register -- if i could figure out how to save and restore that state register, I could probably make that? work.)

?

Thank you!

HP 346A Noise Source Below 10 MHz #file-notice

 

Has anyone investigated the ENR and ENR uncertainty of the HP 346A noise source at frequencies below 10 MHz? Same question for the HP 346B?
?
If so, what was found?
?
Thanks!

Did HP make a Hp Multi-head 51604a Or 9226 cartridge InkJet printer ?

Question:
Hp 2225 InkJet Printer using the Hp 51604a? Ink Jet Cartridge
?
?
I understand that the 51604? or 9226? type ThinkJet /QuietJet cartridge was made in a few different color inks...
?
Did Hp make a Multi-head InkJet Printer,? having Multiple 51604 or 9226 type InkJet cartridges ?

Re: 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 ) ?

 

?
?
A older YouTube fun video? print run competition?? of the Hp 2225a ThinkJet , compared to a Daisy wheel, done by Curious Mark.
?
The Hp 2225 is still quire a nice, small robust platform.
?
?
The reason for the deep dive into the original ThinkJet Ink, was to understand the Ink properties.
?
Intending to examine the 2225 capabilities for 3D printing of electrodes & bio materials.
(? Emptying out the Ink Cartridges ( banking that ), washing out the cartridges,
and then re-filling the empties with various recipes for the 3D printing.
?
However, there will be limitations for the initial 3D printing tests, having only a single cartridge;?
?So will then move to a multi-cartirdge system later after some experience and testing.
?
What other Printing systems use the Hp 51604 type cartridges, but have *multiple* cartridge capability ?

HP83651B troubleshooting

 

开云体育

_After the repair of the low band (up to 2 GHz ) now I have a drop in power at 13.5 GHz .

From the block diagram attached inside the doubler block I can see just switches and the amp for the doubler .

Following the signal from the RF mother board I discover a signal named HAMPLIFY that toggle with HPASSTHRU in band 3 switching off the bypass .

If there are no amplifier in multiplier unit it is an HW SW FW error if there is an amplifier is an amplifier fault ..

If someone Knows the HP83651B can help me?

Thanks

Re: 8131A Error F500

 

Thanks Yves.

That μPA104 device is a potentially very useful circuit block, for analogue/RF or fast digital needs.
I'd be surprised if there isn't a current compatible(ish) part still in production somewhere, but a quick search turned up nothing here.

Thanks again.

Re: HPAK 3D model repository?

 

The button caps themselves aren't radically different as far as I can tell but once you get behind the front panel all bets are off.? Personally I never felt it to be a joke so much as laughing at the inconvenient truth ;-)
?
Re: 8131A Error F500

 

Dave,

This is a high speed device, 500 MHz, and the transitions are <200ps.
It is therefore necessary to use transistors with a gain bandwidth product of 9GHz.
These transistors exist at Digikey. To take one example, the BFG540, unit price for the purchase of 10 transistors, 0.32USD.
I made a quick comparison, but there are many other possible choices. The problem will be the assembly, but it is possible.

Could a CA3046 or 3086 do the job? Subject to voltage and other parameters being suitable, plus you'd need to either dead bug wire it (pinout is totally different) or make an adapter board.

You'd have one transistor spare, but that should not be an issue.

Or, is the original a High Speed device?

Just a thought.

Hi,

?

Here is a simulation to evaluate the BIAS of U203 and its behavior.

According to your results you should be able to know if the BIAS part is normal.

?

I added compensation parts for the signals coming from schematic part 2/4 as well as the circuitry after U203 on sheet 3/4.

The simulation is based on the fact that the signal coming from sheet 2/4, is ±0.2V.

?

If there is close to 0V at the base of transistor Q216, there will be a signal at pin 3 of U203 (nothing at pin 2), but no signal at the output, this is the ON/OFF function.

?

The schematics I have are poor, so there might be some errors.

?

Hope this helps.

?

Yves

Oh there's no way I'm doing all that, I'd sooner sling the damned thing in a skip and cut my losses.? I did try swapping the UPA104 over from the other board and it didn't fix (or change) the fault.?

?

Even though there's no custom hybrid IC's on this board, it's still full of components which you can't buy anymore and have no alternative. Meaning even if I do find the fault, Stands a good chance I won't be able to get the replacement part.

?

What a heap, like I said no wonder nobody wants them.?
