Re: Please don’t upload ArtekManuals.
Yes I agree as well. I have purchased many manuals from them and would not want to disrupt their business.? It was only meant to be used as a reference to help someone to help me troubleshoot.? I have since removed the manual I posted.??

I wholeheartedly agree
! There's no question that Artek needs our business and deserves
our support. Give them any and all business you can. Uploading
their manuals to an open server will kill their business.
And never forget that we would never be able to maintain and
repair our instruments without such a great source for manuals !

Re: HP 8568B bandpass filter alignment.

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 ) ?
the earlier HP thinkjet cartridges likely have a bit more glycerol than modern ink formulations based on the way the ink spread on the fibers at dried first few seconds.

Hi.
Unless the ThinkJet print head is significantly different to what HP do now in commodity ink jet cartridges, there is any number of Black refill kits on the usual Web market places that might do the job.? Just for the ink.
Agreed too, that the ThinkJet is a nice little thing.? I used one some 40 odd years ago, to make PC "EGA" screen dump hard copies, for a prototype "Time Of Flight" MS system I was loosely involved with back then.
Fun work, until the politics started.

Could be an unknown dry joint. Got fixed as part of removing/refitting the crystal?

Re: Please don’t upload ArtekManuals.
That was my mistake Dave.? I brought it up briefly as a resource to help someone help me with troubleshooting.? I can take it down if it hasn't been removed already.? Won't happen again.

HP 8568B bandpass filter alignment.
Hello, can anyone explain me how can i align the bandpass filters of the HP8568B to have it on SPEC?
My rig passes the self test but the values reported are a little out of spec. Non bad but i would like to have it in the<1db range.
But i don't' know what is the correct procedure to align the instrument.

Hi, Don,
Thanks for replying.? I've got a near perfect one coming from Vladan, but I'm glad to know there are some out there available to the group, as there were others who also had some available, in varying states of life.? If the shipper ruins this one, we'll be in touch.

Hi, ? I have an E5818A, and I'm trying to find the procedure to send a SCPI command via LAN so that the E5818A sends a pulse on the BNC TTL1 or TTL2 port, is anyone familiar with this trigger BOX.

Matt, ??? Where are you located? I have 4 good 85662A CRT,s that have been stored properly for the last 20+ years.? They were pulls from 85662A's that had an arc over issue in the post lead - poor insulation issue. They were factory warranty repairs. I have known good post leads with each one. If interested call me, or email me.? I am in the Chicago, IL, USA metro area.

Re: 8566B Performance Verification with 8620C
If it is any consolation, I also cannot afford an 83650A/B/C/D/E/L.? I did work with/use them when I was gainfully employed. I do have an 8341B, but have to repair the? output first.

Re: HP8568B HT BASIC and GPIB NI
With my limited experience with both HT Basic and NI GPIB portal, I found that the default main bus ID was 7xx on HT Basic and the NI GPIB portal defaulted to 14xx main bus ID. It is possible than you need address 1418 instead of 718.

Re: 35665A PSU disassembly
Hi Jeff,
I realize this is a 3 year old post but I found your message while
writing the hp wiki entry for the device.
The service manual (which I have a paper copy of now) doesn't talk
about the power supply in detail. It has 3 or 4 RIFA capacitors and
you will want to replace them. To separate the halves you need a set
of medical forceps to squeeze a plastic PCB standoff that is used to
hold the thing together internally. They were really worried about
vibration with this thing.

What is the trick to getting the case halves apart? There’s a plastic standoff that holds one of the PCBs to the case. This prevents the case halves from separating and I haven’t figure out how to release it.
In the absence of a service manual, any tips?
By chance I was reading the memory upgrade procedure (35665-90060) which mentions a screw in the location of the standoff and says “the power supply assembly will be damaged if the center screw is removed” which is a bit unnerving. However, on my PSU there is no screw, just what appears to be a solid metal press fit insert.

Re: Artek Manuals and HP 3325B
Yes, Artek finally came thru and I was able to repair the unit. ?Root cause of the errors was the 30MHz crystal in the VCO was not oscillating. ?Injecting external signal at the test point restored operation. ?I then removed the crystal and tested it with my 3585A. ?It looked good, so I put it back in and the unit started working. ?I am guessing that the heat of removal caused it to start being a crystal again, weird. ?Either way it has been stable for several weeks now thru multiple power cycles.

Yup:?
??? Anyone have access to a GC-MS lab that might want to elucidate the ThinkJet ink adventure ?
?
Expected major components in the? Hp 51604A ?Thinkjet black ink cartridge:
? ?( ?3.0mL to 3.7mL ; 0.13 fOz)
?
2-Pyrrolidone
Ethelyne Glycol
Food Back 2
Acid Salt 3
water
?
UFI: 6UE7 - CQTV -A205 - GHXV
?
Possibly the MSDS ?(Materials Safety) data sheet ( inserted into product box ), might have additional information ?
?
.... but would be nice to have the GC-MS results,? so that one could make one's own ink, ? as a DIY project !
?
thank you,
