GPIB Toolkit release with HP 3585A/B support
John Miles
Thanks to a lot of help and feedback from Ron, K8AQC and Grant, G8UBN, my
GPIB Toolkit package now supports the HP 3585A/B spectrum analyzers. Quite a few people have asked about these models, so it'll be good to get this release out there at last. All of the principal GPIB Toolkit apps have been tested with the 3585A: 7470.exe: Screen capture (via HP-GL/2 synthesis) SSM.exe: Spectrum recording/playback PN.exe: Phase-noise measurement See -- questions/bug reports are always welcome. As an aside, if I'm not mistaken, all of the common Tektronix and HP/Agilent spectrum analyzers are now supported by SSM, PN, or both. The 3585 was the last analyzer model that could run SSM and PN but didn't yet. As such, this will probably be the last major release for some time. Thanks again to everyone who has helped test various analyzer models with these applications, and/or contributed code to them! -- john, KE5FX |

HP 5342A/5343A Sampler Assembly / Sample Rate Pot Needed
Hi, Anyone have a HP 5442A or HP 5343A Frequency Counter that you have
or are parting out? I need a U1 Sampler Assembly P/N 5088-7022. This is the first module after the N-connector on front panel. I also neet the Sample Rate Pot that sticks threw front panel. P/N WP4N102P105UZ, it is a 1 meg ohm, linear taper pot, pcba mount. Mfg is CLARO P/N2100-3607. Any leads on these parts would be great. Tnx Rich KQ6EF |

Re: Need cross for HP 1901-1096 PIN diode
David,
The only cross reference that I have is: NSN 5961-01-153-7606 also listed is HP 5082-5579 Additional info: Silcon, Glass enclosure, PN type 200.0 maximum breakdown voltage DC Test Frequency 100MHZ; Capacitance .3pF I know you are saying "big deal if I can't find any other cross reference." However I have found a source that mind send you to a supplier of these items. It is: www.GovSupport.com also known as: put in: 5961-01-153-7606 (as the search) and change: "Part Number" to "NSN" Down side is it lists only one supplier with only one item. At least the added info that I give might help your search in some way.

HP 182T
Hi Guys,
Can anyone help please? My HP 182T frame has gone bust. Managed to repair the unit but values for the replacement where not the correct value. If anyone can help I require: 1. 2 Resistors 21.5K 2. 1 Resistor 33.2K 3. Schematic – service manual for the 182T The plug in unit I have with the frame is the hp 8558B. I have already asked but maybe who knows I might get lucky this time. I require the DIV/SPAN knob for the 8558B or, if someone has a faulty one for spares who wishes to part with, please let me know. Thank you in advance Mans. 9H1GB |

Re: Scope Tube Rejuvenation...
lothar baier
First you need to know your filament voltage, you can get this from the schematic or service manual or measure it, be aware however that the filament voltage in some instances comes from a additional winding of your HV transformer and therefore the frequency can be quite high (several kHz) sencore has listings for several scope tubes in the little book that comes with your CR7000 and if its not in there inquire with sencore they might be able to help you out.
If you encounter the same tube over and over you might consider building a adapter, you can pull a CRT socket from a salvage unit and buy a universal adapter from sencore and piece both of them together.

Re: Circular Polarisation in Waveguide
lothar baier
HFSS is on my alltime wish list , i have used it at motorola before and its a good tool however i couldt find the spare change to buy it :) the sucker is just too expensive, spending the annual maintenance fees on my MWO installation almost causes a marital crisis in this household and thats only $2000 so even if i would have the $ then my wife would probably get a heart attack me spending this much on SW.
The problem is that there is not much cheap stuff out there if it comes to true 3D EM Simulation, there are some planar 3D tools such as EM3DS that have good freeware versions or sonnet lite but they are only good for planar designs. I found another tool WIPL-D which is reasonable and has a shareware version but dont know yet if its any good. As to the Antenna, its just a regular circular horn antenna, it doesnt have to excite a dish or something, basically its used in a target simulator to test sport radar guns, the guy shoots into the simulator from about 6ft away and then reads the simulated speed on his gun Chris Bartram <yahoo@...> wrote: Lothar Ok guys this is not directly related to agilent t+m but imThere are number of ways of doing this, but at 36GHz there's a rather more limited number of choices.

Re: Scope Tube Rejuvenation...
Hi Mark,

If you check the archives here, and at TekScopes, you will find several articles where I detailed the process using a CR-70. The CR-7000 is the same, only better. In the book that came with the CR-7000, there is a detailed discussion of the process. There are also several papers on Sencore's website. And, in the test book, you will see settings for several generic scope tubes, such as the 5UP1. All scope tubes are basically the same. The Sencore CR-70, and CR-7000 have a universal CRT adapter available. Essentially, it is a bunch of micro grabber clips connected to the Sencore's test cable. The heater is obvious, the cathode, too. The control grid is the first electrode after the cathode, and the focus grid is next in line. The gain test uses the cathode, control grid, and the next anode in the line to run the gun as a triode. The Sencore does its rejuvenation using the control grid as the anode and draws much higher than normal current out of the cathode. To aid in that process, the heater voltage is raised 50% over normal. In case you are worried, the control grid on a CRT is nothing like the grid on a triode. It is a metal cup with a hole in its center for the beam to pass through. Beware! HP heaters often use non-standard voltages, such as 4.8V. -Chuck Harris Mark wrote: Hello all... |

Re: Circular polarization antenna question
dave powis
Septum feed is going to require some smart machining at 36GHz - the diameter of the waveguide is around 0.71 lambda - haven't done the sums for 36G, but at 10G thats just about 20mm. You'll also have to check out what the matching is to whatever reflector you're using (I'm assuming that this will be at the focus of a small dish?) CWST (circular waveguide septum transformer) and RWST (rectangular WST) feeds are optimum for f/d of around 0.4, and even then benefit from some cavity rings a la VE4MA (see W1GHZ work) or Chapparal (see W1GHZ or recent practical work by DL4MEA). To adapt to other dish f/d ratios flared horns work well on the front of the feed.

It's done with a hybrid ring made out of coax. Three sides are 1/4 wave and the fourth side is 3/4 wave.
