Agilent Network Analyzer, read and display traces on pc.

[demo]

hi to all,

i am using the agilent E5071C network analyzer.

i am taking measurements of;

s11, s22, s21
s11, s33, s31
s11, s44, s41

i am able to setup the N.A. but i need to read the 3 traces on all 3 channels.

i can extract the traces i need, but the refresh rate on my pc is very slow.

does anyone have any idea's on how to speed this up?
does anyone have  examples of something like this already?
is it possible to query more than one trace per channel at a time?

p.s.
i am using a usb to gpib interface to communicate with the Agilent N.A.

thanking you all in advance,
D.S

Which environment/language are you using for the communication?  Have you seen the device drivers for the E5071C?  http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=5692

There are examples along with the driver API.

hi mark,

thanks for your reply,

yes,  i am using the device drivers you listed, also i am using labview 2009.

the problem is, that the response time and refresh rates are really slow.

i would have like to display the 3 traces per channel (3 channels total) on the vna and a pc gui.

do i really have to read all 9 traces sequentially?

is there a way to read the 3 traces on, say, channel 1 of 3, with one command? and loop that?

better yet, all 9 traces at the same time?

by the time the pc performs the functions, it is about 2 seconds before the N.A and pc gui get refreshed.

trying to tune with an n.a, this is an eternity.

i am wondering if there are any possible solutions...

thanking you in advance,

Hi d.s,

There are a number of things that could cause your system to be slower than expected, such as opening and closing resources every iteration of a loop.  We'll need to know more about which VI you're using.  Are you using one of the examples that came with that driver?  If so, did you modify it at all?  Can you please send the VI you're using, or an image of the block diagram?
