Re: [time-nuts] LAN/USB to GP-IB/HP-IP Adapters

[Orin Eman]

I have successfully used an Agilent 82357B USB adapter - there are plenty
on eBay from Chinese sellers...

I got NI Visa to talk to Agilent, er, Keysight IO Libraries and access a
3456A attached to the 82357B.  That's the simplified version... the 82357B
was on a remote system over a WiFiI link and the Agilent IO Libraries took
care of the details.  It was painful.  Don't try this.  At one point, it
managed to access the wrong device on the remote system!  There was only
the 3456A on GPIB and a 34461A on ethernet, but it got them mixed up.

However, I'm not sure that NI Visa on its own with an NI adapter is less
painful.  It refused to find devices after I accidentally deleted the name
of a serial port in NI Max (double click the name, hit delete, click
somewhere else; easy to do when you are trying to get rid of a phantom COM3
that turned out to be a software modem).  Attempts to refresh the device
list put "Visa Error" in the device list.  Clicking on it gave a useless
message about the configuration being incorrect, but no real way of fixing
the problem.  I'm told uninstalling/reinstalling NI Visa is usually
required.

For under $200, I think I'd go for the NI USB adapter - hopefully it would
come with support.

Good Luck, Orin.

GPIB-USB-HS is available for under $200.
Can anyone comment on what's available?


I have this:
http://prologix.biz/gpib-ethernet-controller.html

There's also USB version available, but personally I perfer ethernet 
because it's so much better when instruments are accessed from multiple 
computers. It's always connected on the network so it's always ready 
when needed, without plugging anything etc.


Never used it with LabView but according to websites it should be supported.

AFAIK

The "Lock" pin is loading the 1PPS pin , meaning if you have a LED on the 
"Lock" you should buffer it, else there will be no 1PPS.

But -5v doesn't seem right.

That makes sense. Thanks! That’ll help when it comes time to attempt to 
calibrate it. In this case, I doubt the seller speaks enough English to ask. 
But I can look at all of the pinout variations to find one with a TX pin on 
that wire.

Re: [time-nuts] FE-5680A pin 6?

[Bob Camp]

Hi

There are far more unique pinouts for the 5680 than anybody can keep track of. 
Three also is very little that ties the markings on the unit to a specific 
pinout. If you are getting -5V, my guess is that you have an RS-232 output on 
that pin. 

Normal drill is to go back to the seller and see what they do or don’t know 
about it.

Re: [time-nuts] FE-5680A pin 6?

[Nick Sayer via time-nuts]

I figured it out. I was counting the bottom row from the wrong end. To actually 
find the PPS signal I had to set my scope to one-shot triggering at a very fast 
timebase setting (I used 500 ns/div). It’s only 1 µs wide, but it was there.

Re: [time-nuts] FE-5680A pin 6?

[EB4APL]

Hi Nick,

FE-5680A is a whole family of Rb oscillators that have in common the 
case and name but the functionality, connectors and inner stuff varies a 
lot.  Some are programmable on a wide frequency margin, others has a 
fixed frequency output, mostly 10 MHz.  The connector arrangement also 
varies but you probably are referring to one with the P/N 217400-30352-1.
These units have a 1 PPS output on pin 6, the signal is normally at 0 
volts with a 1 uS wide 1PPS at about 5 volts.  This low duty cycle 
signal is difficult to see on an analog scope but you can see the 
trigger light blinking at each pulse.
The 1PPS signal is buffered by U503, a 74ACT240SC-ND chip. A word of 
caution here: since the driver circuitry is shared with the Lock output, 
an excessive (ie. a LED) load on the lock pin cause the 1PPS to 
disappear.  Please recheck the output voltage on pin 6, -5 volts doesn't 
make any sense for me, even with a driver chip failure (I have busted 
mine some time ago by connecting the +15 V power supply to the 5 volts 
input, a consequence of the disperse information about these units that 
circulate on Internet. Apparently on some units pin 6 is the +5 volt 
input so you can also ruin the driver following this wiring list.
If you are interested I have the board schematics that was reverse 
engineered by a member of this list who unfortunately I cannot give 
credit because I don't remember who is.  I can send it it directly to 
you if you want it.


Regards,
Ignacio EB4APL

What I wonder about is pin 6 on the connector. Google results seem to indicate 
that that’s supposed to be a PPS output, but what I get on it is a fixed -5v or 
so. Anybody know what this signal is supposed to be?

Hi Brooke

Afaik the Agilent USB GPIB adapter can "Speak VISA on Windows" with 
Agilents windows driver. But no VISA support for Agilents under Linux, as 
Agilent doesn't make drivers for linux :-(

See this Agilent PDF
http://cp.literature.agilent.com/litweb/pdf/5990-3731EN.pdf?cmpid=1273CN


And have a look on *bay for :
"Agilent 82357B USB-GPIB Interface"


According to this thread , even the "real ones" are clones (work ok)
http://www.eevblog.com/forum/testgear/flood-of-new-agilent-82357b-gpib-

I have a Beiming and an Agilent (prob a clone) , both works fine with 
liunx-gpib.

Re: [time-nuts] LAN/USB to GP-IB/HP-IP Adapters

[Ole Petter Ronningen]

I have both a chinese clone 82357b and two NI GPIB-USB-HS. If you will
write your own software for aging test-equipment, my experience is that a
clean NI solution with GPIB-USB-HS and NI 488.2 is a *lot* less painful
than trying to get Agilent GPIB to play nice with the NI software-stack.
Speaking for myself I could never get it to work satisfactorily on Windows
(never bothered to try another OS), just lots of weird unexplained
problems; sometimes working, sometimes hanging, sometimes requiring the
sacrifice of a chicken. Might be the chinese clone adapter, though, I never
tried a genuine Agilent 82357. Come to think of it, the NI's came out of
china as well, so might also be clones. Just way better clones. :)

If you are writing your own software from scratch, consider the Prologix.  It 
includes reasonable documentation.  No drivers required.  It uses one of the

I have one each of the HP and NI USB units, and have both sets of libs

the size of each company's download is absurd!  So,ething like 800MB between 
them.

Re: [time-nuts] LAN/USB to GP-IB/HP-IP Adapters

[Brooke Clarke]

Hi:

Got one of the new in box NI GPIB-USB-HS (not GPIB-USB-HS+) units on eBay.
More after it arrives from China.

SparkFun is out of their Inventor's kit, I'll get it when back in stock.  It includes their Arduino Uno clone (probably 
better than a real one for less money) and the LINX (not Linux) language allows using the Arduino as an I/O device so 
LabVIEW can talk directly to anything connected to the Arduino.  So all the shields and add-on hardware for Arduino now 
can be easily connected to LabVIEW.

There's also a LabVIEW to Arduino compiler, but that's for another day.

PS for a number of years I was an official NI certified instrument driver 
specialist.

Re: [time-nuts] LAN/USB to GP-IB/HP-IP Adapters

[Brooke Clarke]

Hi Jim:

LabVIEW Home is the full development version that normally sells for thousands of $, but for a home user sells for $50.  
There's some watermark on the front panel, but otherwise is fully functional.  I haven't got into the Arduino because I 
don't like C.  LabVIEW is the highest level language I know of (probably because it's a graphical language) and in my 
experience very productive.  The motivation for NI may be the Maker movement, since the home version shows up on their 
Maker Hub web page where they are supporting a number of maker type hardware platforms such as Kinect One, Digilent 
Adept FPGAs, AR Drone, LabVIEW dashboard (Android - iPad) Interface, Phillips Hue, Kodi (radio & TV remotes), Leap 
Motion Controller, LEGO Mindstorms, LINX language for Arduino & ChipKIT I/O, NEST HVAC, PS4 Controller and the XBox One 
Controller with LabVIEW drivers (see maker hub libraries below).

http://www.prc68.com/I/LabVIEW.html
https://www.labviewmakerhub.com/
https://www.labviewmakerhub.com/doku.php?id=libraries:start

By using the SparkFun Inventor's Kit and HP-IB instruments I can combine high 
level instrumentation and bit banging.

I'm currently learning about gyroscopes and in particular north finding gyros. Leon Foucault (of pendulum fame) is also 
the father of gyroscopes in the modern physics sense (he also named them and came up with laws parallel to those of 
Newton).  A gyro is sort of a pendulum that keeps going round and round.  Prior gyro work was more in the toy realm.  As 
part of that my first project will be for testing DC PM motors where measuring voltage, current and RPM are the key 
parameters.
