GPIB readout from spectrum analyzer HP4195a

i'm also having trouble reading data from an HP4195a via GPIB. i tried running the vi provided by albert but it gave an error message about the property node (in initialization vi). help, please? much appreciated!

Can you post the error message? with number.

Maybe I can see what happens

hello albert,

i tried running your example.vi in hp_network_analyzer.llb. both the "read trace" and "initialization" subvi's are not executble. (i'm running labview 8.0). the "read trace" vi shows an error in the nested boolean case structure. a property is not defined and not connected. you can find that property node near the "number to decimal string" function, the input of which is not connected.

the "initialization" subvi has an error similar to the one described above. on the far left, the first case loop has a property node that is not defined and not connected. you can find that node near the constant "10000".

i'd really appreciate your help on this, thank you in advance.

here is the version in 8 with correct property nodes.
getting it right from 4.01 is difficult it seems

I can make it available in 7.1 also if you want or if you have 8 save it for 7.1

The problem is in the step from 4.01 to 8 two property nodes have the wrong selection

one is timeout the other primary gpib address (that is all)

So you even can update it by yourself.

hello albert

please make it aviable for 7.1-we only get 7.1 from our  technician-school.

we only need it for the hp 4195a.

much appreciated!

Hi

I recompiled and found some lv4 subvi's that I added.

I don't guarantee anything about the tcpip stuff (some wires were broken, and maybe fixed wrong) but the gpib stuff should work

hi albert

thanx for the fast answer and the driver.

we still have a error message -1073807339(hex BFFF0015) occured at visa write in

nw analyzer initializevi.->example.vi.

and also it says that the date server queue .vi is missing.

did we have the problems cause we use the agilent usb-gpib interface 82357a?

did we need the IO software from the interface or need another driver from hp for the 4195a?

thanks for your help!!!

greetings olli

Hi

You need the visa for the agilent hardware and uninstall the NI GPIB visa first.

The Date Server VI should be in the llb, I'll check it later today
