Re: OT fluke 8060A battery eliminator
Steve
Thanks for the responses and advice guys.

Upon closer inspection, the writing on the meter does say A81. Thanks for that clarification. I thought that isolation might be an issue with the run-of-the-mill wall warts. I'll most likely use an on-hand wall wart for lower voltage measurements, which is what I use the meter for mostly when it's on my workbench. Over the past few years I've often forgotten to turn it off and end up using enough 9V batteries to make it worthwhile to consider powering it from AC. Wonder what size or type of plug fits the battery eliminator jack on the meter? Thanks again! Steve K8JQ jbarnes wrote: Steve, |

The TCL scripting language has good support for GPIB. It is pretty easy to write a script in TCL that reads the 5328A once every so often and writes the result to a text file. The text file can then be read by Excel for further processing. Jeff -----Original Message-----

Need logging help with hp 5328a
Hi James:
Spark Fun has the GPIB-USB Controller. In addition to the EZ GPIB software there's also a "Plotter" program at: that's designed to process time interval data (like you would measure with the HP 5328) and from that get Allan plots. Note for high stability work you don't have time to make frequency measurements and instead make Time Interval measurements, typically comparing a GPS timing receiver's 1 PPS with a 1 PPS derived from you oscillator. You might also consider joining the Time Nuts mailing list Have Fun, Brooke Clarke, N6GCE -- w/Java w/o Java |

I understand the situation. In the hand held meters like the 8060A the battery eliminator jack is connected to -ve input terminal. This means that whatever you connect the input terminals on the meter appears can appear on eliminator jack. In the bench meters such as the 8050A, the transformers were potted and have an isolation voltage of 4kV. I suspect that the fluke eliminator was of similar construction, probably heavier than normal insulation on the leads and a molded plug. The manual for the 8060A is available for free from www.fluke.com IF you are measuring low voltage, less than 50V you can use any wall mart with the right voltage and polarity. If you are above 50V use the battery. I would also recommend the fluke 8050A for bench use. Very good value on eBay. Make sure that you get one with a good LCD. I hope this helps.

Thanks for the help. I have a Fluke 8060A multimeter that I'd like to power with external DC when I'm using it on my workbench. The instrument has a jack with the following text printed next to it: BATTERY ELIMINATOR JACK CAUTION OPERATIONAL HAZARD EXISTS IF BATTERY ELIMINATOR OTHER THAN FLUKE ASI IS USED. Or maybe that's AS1. Did Fluke make that model of battery eliminator? I don't find it on eBay. What would be the "operational hazard" if I powered the meter from a wall wart? What size/type plug does it take and how should I wire it? Thanks. Steve K8JQ jbarnes wrote: Steve, |

Here are my $0.02 on the subject:

The first step will be to get the data out of the counter, and that will require a GPIB controller of some sort. There are 3 basic types that I am familiar with. 1) The plug-in card type, with the older AT style plug-in card being fairly cheap on eBay ($5 to $10 for most), but not many computers have suitable slots, or the more recent PCI type, but these cards are still relatively expensive on eBay ($50 to $150). One problem with the plug-in cards is that you will need the computer fairly close to the equipment because GPIB signals don't travel too far, and the cables are bulky and expensive (see below) 2) The USB type, with the Prologix adapter () being the least expensive "new" USB controller you can buy ($125), and considerably more expensive models from National Instrument or Measurement Computing. The Prologix type has the advantage of working with John Miles' software, and hopefully soon with my own software. USB has the advantage of being able to operate farther from the computer, and most USB controllers don't require a separate power supply. The Prologix controller also has the advantage of plugging directly to the back of the instrument, so you save the GPIB cable, but you need the clearance in the back of the unit. The USB controllers also work well with laptops. 3) the RS-232 type, with models from Black Box, IOTech and National Instruments and probably others, which can be bought fairly cheap on eBay, but you may have to wait a little, as they are not very common. I paid anywhere from $20 to $50 for those, and I have several. In general, serial-GPIB controllers have non-standard protocol, so you must write software for the model you have. I have models from BlackBox and IOTech. The BlackBox is a medium size enclosure that requires a 9-10V DC supply to operate, the IOTech Micro/488 is much smaller and runs from power stolen from the serial port, pretty neat (however, it will not work if there are several unpowered instruments on the bus). Be careful that BlackBox sells two similar models, one is a true controller, that's the one you want, the other is an adapter and has limited functionality, and would be useless for your purpose (it is intended to drive plotters and such). The difference between the two is in the EPROM and the silk-screen on the front panel, the hardware is the same. I like the serial adapters because they are inexpensive and don't require to go inside the computer. They can easily be swapped from one computer to another and work well with laptops, which cannot use an AT or PCI internal controller. Then you will need a GPIB cable, cheap on eBay. Industry standard GPIB cables are very stiff and expensive when new, but cheap (yet, still stiff...) when bought on eBay. Personally, I have bought several cables on eBay, but I also make cables using ribbon cable and IDC connectors from Digikey (male connector is PN: MDC24K-ND, female connector is MDF24K-ND, they cost about $5.50). It's not much cheaper than true GPIB cables from eBay, but much easier to daisy-chain from instrument to instrument. Finally, you need some software. Let's quickly pass over National Instrument's LabView, which is definitely not priced for the hobby market. You can try a free program called EZGPIB by Ulrich Bangert which includes a scripting engine which may allow you to do what you want without having to buy a visual studio development system or some other compiler. While you won't need a compiler, you will still be required to write code using the scripting engine that's built into the program. There may be other such free software, but I have not come across any. I am not sure which GPIB controllers are supported, but I am pretty sure it includes the Prologix. I have started working on software to take advantage of the GPIB ports on my instruments, and while not quite ready for prime time, it is buggy but usable (at least for me). For now, this software only supports the BlackBox and IOTech RS-232-GPIB controllers, but I am working on the Prologix controller. This software supports a number of instruments (right now, HP 8656A, HP 8657B, HP 3478A, HP 5316B, HP 5334B, HP 5370A, HP 8672A, HP 8673M, HP83640, HP 3586A, Fluke 8860, HP 59306A, HP 59307A, HP 436A, HP 437B) with more coming. Functions that are supported are of two types: Plotting (such as sweeping the frequency of a signal generator and measuring power with the HP 436A or the HP 3586A for instance) and Logging, where data from a voltmeter, HP 3586 or counter is collected at a given periodicity (from a fraction of second, when practical, to many minutes). Logging supports the counters and voltmeters listed above. Logging can also automatically scan the HP 59306A or HP 59307A switches to log multiple channels with a single instrument. I believe it would be simple to add the 5328A once I look at the commands. If you get one of these serial controllers, or if you get a Prologix and are patient, I'll be glad to let you try my program. Didier KO4BB James Hickox wrote: Hello all, |

DNS Changes
This is a general announcement to the TekScopes, HP gear, and TestGear mailing lists.
I will be updating Blue Feather's DNS this weekend, including some IP address changes. This may affect those of you who access the FTP archive. The initial changes should be in place shortly, though it could take up to 36 hours for them to propagate fully through DNS. This could mean an inability to reach the site for a time.

E4411B Spectrum analyzer - front panel keys stopped working :-(
Hello Folks,
I picked up an ESA portable spectum analyzer (well, it has a handle) used this summer and the front panel keys have just stopped functioning. Nice. Reading the service notes for this guy I see E4411B-04 which ID's a problem with green flex circuits making the front panel not work. Darn, I opened mine up and I've got green flex circuits alright. I was hoping someone in the Santa Rosa service center might be reading this group and help me repair this thing. An Agilent repair part number and a phone contact for the service engineer incharge of ESA products would be wonderful. The Agilent repair fee is much more than I paid for this whole thing and I was laid off from Agilent over a year ago, I'm working on a low cost antenna analyzer and really need this darn thing to work. Any help would be much appreciated. Thanks, Lee Carlton |

Re: Need logging help with hp 5328a

You can probably use the QUERY.EXE console application from my GPIB Toolkit

suite to do this. I also include specific example programs for the 5370B and 5345A counters, so even if QUERY.EXE doesn't work with the 5328A directly it would probably be easy to adapt. See for more info on that. Ultimately you may want to build a program to output CSV (comma-separated variable) files, but that's just two or three more lines of C code. -- john, KE5FX -----Original Message----- |

other "waterfall" programs under Windows on a PC and input the receiver audio to the soundcard. If your receiver drifts you may need to put a stable crystal controlled singal on screen as well and this system will plot your vfo drift all day if you like and give you a reading on how good your central heating is. I can run 24/7 with rx errors of less than 1Hz on 160m These programs written for very narrowband receive modes are great bits of test equipment, and all for free. 73 de Alan G3NYK ----- Original Message -----

A couple of options for the hard part- the hardware to do the GPIB interfacing. See attached URLs for USB/GPIB devices. There are others. Shifting the raw data into excel should not be an issue. DaveB ----- Original Message -----

Re: Need logging help with hp 5328a
Pete
James,
I know what you need to take readings from your 5328A with your PC; but it may not be as simple as you'd like. Software is the hard part since I don'y know of any public domain instrument interface; I have a copy of HP/Agilent's VEE which runs fine, but is probably not freely availavble. NI Labview should work fine also & older copies are easier to find. Next you need a GPIB(HPIB) board for your PC; a PCI/GPIB interface is simplest & they are readily available. Finally you need a GPIB cable from the counter to the PC. After that, it's all downhill. There must be a simpler way than this; let's hope a later answer is better. Regards, Pete Rawson |

There are a number of documents on Agilent's site that are intended for other instruments but should still be helpful in developing an understanding of dynamic signal analyzer concepts. Search there for "dynamic signal analyzer" or similar. Also, according to the Application Notes Index, you might find these helpful if you can find them: AN 243, The Fundamentals of Signal Analysis, a 60 page primer on dynamic signal analyzers.
