Re: HP 4192A GPIB measurements
Notepad seems to have the find and replace but they do not work on my computer (Win7, works perfectly). I restarted my computer to see if that was the problem. It won't even find zzz that I typed in. I like MS Word because I can turn on hidden punctuation. As long as I save as Text it does everything for me editing the files for plotting.? I also like other features with special character sets and Greek symbols which I don't think I can do here. It is worth the trouble to explore all the features like search and jump to a page instead of scrolling. As I mentioned Tab is ^t and Linefeed is ^l but you can find them in Find>more>special (or replace). Peter

Re: HP 4192A GPIB measurements
I'm the last person on the planet to defend anything from Micro$oft but isn't it a bit harsh to blame an application if you download it from a dodgy site?
That aside FWIW I like Notepad++, I'm not a proper programmer but I've used it for years. It can be used in a basic way but is highly configurable and 'knows' a bunch of languages so when writing in EzGPIB for example, just set it to Pascal and keywords and so on are highlighted. Lots of plugins around, like a very handy hex editor/viewer which I found invaluable when trying to figure out what the heck was going on when downloading data sets from a spectrometer using EzGPIB as the controller.
Oh yes, it's released under Gnu license and so it's free too!

Re: HP 4192A GPIB measurements
It's been several years, but I had downloaded a program from a site that had been infected. When I ran it, it opened Notepad and added a bunch of lines to the Registry. I had to manually search for each line, and delete them. Ii haven't allowed Notepad on any of my Windows computers, since then.

Re: HP 4192A GPIB measurements
How do I take this private? Thanks Dave for the advice.? I took a Fortran programming course back in the '60s then, when the programming was taking over, I told my boss I was better at electronic design but would never be more than a mediocre programmer. He hired two full time programmers and I was back to what I liked. The Intel 8008 chip came along and I built a computer controlled by pink paper tape from a Teletype.? This was an improvement over boxes of cards and evolved into an instrument controlling a Nuclear Data Pulse Height Analyzer and storing the data on Philips audio cassette tapes (hard drives had 30" platters or 24" long drums back then). It ran on Fortran and Assembly language.? I kept my career interesting and moved to RF in Accelerators and a Superconducting Cyclotron, and a good pension.? Now I program PICs in CCS C using the MPLAB IDE. I am happy with C, and EZGPIB with a minimum of Pascal.? I lost interest in Arduino since I showed a friend how to solve his problem and he said Arduino C does not have that function. I like CCS C. A few of weeks ago I installed MS Visual C++ and ran a Tutorial. I like it but will never be an expert.? I can tolerate Raspberry Pi and Linux. I don't want to learn any other languages. I don't want to be a programmer. I have only seen one post (using a macro in Excel) on gathering data and plotting from HP test equipment. This is despite starting a group for EZGPIB back when I was trying to get data from an 8505A VNA. I see some programs in the EZGPIB folder but not many. It just seems to me that I am the only one actually reading and plotting from these machines. I am not referring to newer instruments like the 8566A or 8753B that will spit the plots out for you to the 7470A emulator. These 419x series are 1980 vintage and used analog plotters.??

HP 3476A hybrid 1813-0091
Hello folks,
I have two HP 3476A DMMs whose hybrid chips 1813-0091 have failed. I know they've failed because when I replace with one from a working 3476, everything works.
I'ld be most grateful for either a couple of these chips, or a couple of examples of the whole DMM where other things have failed.

Means: Normal status-C Series mode measurement-Normal deviation measurement, Uncalibration-D measurement-Normal deviation, Frequency in kHz (correct me if this interpretation is wrong. see Table 3-25 page 3-74)
C is measured correctly, D measurement cannot be performed because |Z| is less than 5% of full scale (Table 3-3 page 3-17)
The displays show .0F1? ? ? ?--.-? ?(with the decimal point positions depending on the frequency) for |Z| and phase. Table 3-3 says this means Measurement cannot be performed because the measured value of |Z| is less than 5% of full scale (Table 3-3 next page 3-17). Ah, then it's now programming step 2: Each value you take should have an error flag with it (I suggest looking at enum, and then perhaps at records. So what you do is to look at the first set of letters, easiest to just split off the first response, look for the "," here. Then look at the first set of letters, that tells you if the thing is valid or not, it's either 4 letters or 1 letter, but easiest is to find th eposition of either the + or - character. Take whichever is less (if no plus, then look for -, etc...) that's the position of the sign for the number, or if you want, look for each of the possible UDFN combinations, set the error code for that ("good" is a valid error code). Once you do that, then the rest of that little substring is a number. Look at the functions that tell you where a certain character is in a string, then look at routines to copy part of that string. It's just like removing UDFN, for instance, except this time you know what you got rid of. Harvey It is best to manually look at the spot frequencies in |Z| & deg mode the way it boots up to make sure you are not asking the impossible.?
The manual is complicated with tables all through it. I am copying many into notes on setting up and using this instrument.
I am using MS Word to edit the files now so I don't miss important annunciations.

Re: Help to fix power supply (A80) of an old HP 3586A
Yes they are off the board. So by adding external pass transistors to the board you can easily troubleshoot what ever happens. Your not passing any real current so anything will do. Believe me you will need easy access to the board without the rest of the meter. :-) Plus if a regulator goes nuts and they can because of the base no damage to the 3586. The smoke is self contained.

As a reference, from the Maury Microwave precision calibration catalog the dimensions given for the two impedance N connector center pins are:
50 ohm: 0.0650¡± +/- 0.005¡±
75 ohm: 0.0355¡± +/- 0.005¡±
For commercial-grade field-replaceable N connectors (the ones most people are used to) it has been found that these dimensions may vary a thousandth or two.? From the above you can see why damage will result if the two different impedance connectors are mis-mated.
?
I sometimes receive emergency requests from engineers who do not have a 75 ohm connector immediately available so will take a 50 ohm center pin and turn it down in a jewelers lathe to the proper diameter for 75 ohms use.? Such an action is usually done when the need is imminent and any variations in the physical dimensions of the connector that may affect minute impedance variations is not important.
If you are really determined to find out what the pin diameter of an assembled connector is, I recommend obtaining an inexpensive hand-held optical comparator and an insertable reticle that gives diameter measurements in the range needed.? That way you can simply place the comparator over the end of the connector and get at least a close estimate.

I just received an HP 8903 B when plugged in the display seems to be incomplete some of the numbers aren't completing and I received no error but I cannot go any further the screen just displays incomplete characters on both sides is anyone have an idea what this could be so far I've checked all the power rails they seem to be okay and on it's a board with the LEDs I am getting a flashing LED as I press the buttons in the front. Can anyone give me a starting point as to what this could be I suspect it's probably something to do with display bored but I'm not entirely sure or possibly even a ram issue or ROM

Re: HP34702A Ohms converter issues
The ref current through R55 is ~1mA, R54 100?A, R53 10?A and R52 around 1.4 ?A - so the current is noticeably higher on the 1M¦¸ range.? Since the ohms converter output goes directly to the display (and not through the DC trimmer), I suspect it's supposed to be powers of 10 by range in order to not require any further gain shift.? R52 measures 900.0 k¦¸, incidentally, and the others are similarly exact.
Time to take a closer look at the passives around U3, I guess?
Incidentally, DCV goes through the range trimmers and then straight to the display - there are no active components in the path.? And the display has an auto-zero circuit so it shouldn't be dependent on the analog stuff preceding it.? There may be issues in the display module too...
