I cannot seem to successfully run any of the USB tests in the application. For example, for the Host Low Speed Signal Quality Test yields this error:

Could not find C:\Documents and Settings\All Users\Application Data\Agilent\Infiniium\Apps\USBTest\Project\LSDownstream0.html. Please make sure that CHANNEL2 is connected to D- and CHANNEL3 is connected to D+. Also make sure that you have selected the correct Test Type in the Configure Tab. For low speed devices without captive cable, please select "Low Speed Near End": for low speed devices with captive cable, select "Low Speed Far End".

High speed yields a similar error.

The probes are set up properly, and I don't see what being unable to find a web page has to do with setting them up incorrectly either way. Uninstalling/reinstalling the test app does nothing.

A side concern: The website says the version is 3.40.0006, and so does the installer. The about page, however, reports itself as 3.40.0005.

No one else has this question

What scope model, and what version of scope SW?

Have you looked to make sure that the file in question is actually there? All of the compliance tests provide html output, and use html input files to provide the framework for that output.

The scope is an MSO9104A, and is running software revision 02.50.0001. I believe that the test app wants 0.2 or higher.

I went to look at the location it was referring to, but there was nothing in an HTML format there. I was guessing that the software was supposed to generate the page.

Thanks for your help!

First, you should update your scope to the newest firmware. Version 3.06.0004 is on the web at: http://www.home.agilent.com/agilent/facet.jspx?c=184248.i.3&to=80055.k.3

The update will take a while because a few of the FPGA's in the scope will need to be reprogrammed, which requires reboots, then you'll probably need to calibrate the scope. A newer version (3.10) will be out in a week or two, so you might want to wait. If you do that, the problem won't be resolved until you do.

Whether you choose to do the update now or later, I would recommend that you use the link that says "Download and update for Infiniium base software plus all Infiniium applications". It's a 2GB file, but it will make sure that all of your applications and the firmware, have the latest, correct versions

Somewhere along the line, a bunch of files moved to new locations, and while I didn't ask what version you have of the USB application, I'll bet you have an incompatibility between the scope firmware and the USB application. A complete update is the best way to fix that.

You should also register your scope with Agilent for free SW and HW update information at http://www.agilent.com/find/register

By the way, the latest version of the USB SW is version 3.70.0006

Give this a try, and let me know how this works out.

Sorry, I was misreporting the USB test app version. I did the recommended full update; I'm still having the same issue. Test app is 3.70.0006, while the Infiniium software revision is now 03.06.0004. The test still returns with the same complain as before: a lack of HTML file.

Looking around the appdata folder that they're referring to and nearby folders doesn't seem to show any sort of html files at all.

It's time to call your local support center. I don't have a scope that I can look at right now. If you're in the US, the number is 800-829-4444.

The previous problem is gone, but through no longer having to deal with it rather than it being fixed. However, there's another issue, though only tangentially related to the scope in particular.

Does the USB HSET tool require a separate PCI host controller, or should the one included in the motherboard be acceptable? The tool doesn't seem to recognize any host controllers when I start it. I'm running Windows 7 Enterprise, 64 bit, if that's any help.

Also, is there any particular reason that the Inrush Current Test does not list the 9000 series as a compatible scope? It is also not acting as expected, and I'm wondering if that's because of some particular incompatibility. I don't see why it would be, though; it seems to just be reading for a current probe edge.

"

You need to use a separate controller, since once you start HSET, it takes over the USB control on the local PC. The scopes all use USB to communicate with the knobs, switches, and mouse, so that won't work.

"

"

There are a number of tests where the 9000 isn't listed, mostly lower speed. I don't know the answer to your question, and the expert is out this week. It might have been an oversight, or a deliberate decision since the 9000 has a higher noise floor than the other listed scopes, which would cause more test failures.

9000A series is just fine for the inrush current tests.

on the win7x64 machine:

uninstall HSET.
install the command verifier (CV) tool for win7
then install hset

or use an XP machine.

there is also a 64 BIT version of hset...

http://www.usb.org/developers/tools/

if that don't work, contact the USB tech admin.

and you CAN install hset on the scope, but as AlG points out you loose control of the scope. So. if you use a PS2 mouse and keyboard, and are willing to give up the front panel, it can work... you have to connect the mouse and keyboard b4 u turn it on. then, to get the front panel back, I think you need to disable HSET under HW manager (I think)We DO NOT recommend putting HSET on the scope.

Okay, thanks! I did try putting the software on the oscilloscope at first; I had to hunt down a serial keyboard adapter after that. =S It seemed to wrest control from the scope before I had even run it.

Even if I should use a separate host controller, should the HSET tester detect the motherboard's USB host? It claims it hasn't found any host controllers when run.

I ask the current question because I seem unable to obtain inrush current data, possibly because I can't seem to zero the probe (N2782A attached to an N2779A). It idles, with no cable, at 43.7 mA. I've turned the zero-adj knob as far as it can go, and demagnetized. The power source measures 12.27V output. The probe is new, purchased just for this purpose. Am I missing something?

ok. get out the manual for the current probe. There is a large screw under a sticker that I suspect needs to be adjusted. this is the course zero adjust.

default the scope
connect current probe; I think this probe will ID itself and set units and scale; if not, set them
deguass the probe.
set fine zero adjust to middle
set scope to most sensitive setting
use course adjust to center the signal at zero, dial in with fine adjust
now set up the probe for the settings that it will be used at (offset, scale, timebase)
turn on a fullscreen dc rms measurement
dial in the fine adjust to make the DC rms as small as possible.

Thanks, ksmith! The current inrush tests are working properly, now.

I've obtained a PSI-Express USB Host controlelr card which purports to be EHCI compliant. It installs correctly, etc, but does not apepar to be functioning, etc, but the HSET test app doesn't seem to notice it. It there something I have to do with the USB 2.0 CV beforehand, besides installing it? I've turned off the UAC as mentioned on the page.

EDIT: Also tried both 32 and 64 bit versions (using 64 bit Enterprise Windows). Coworker tried with a similar card/computer/general setup, couldn't get HSETT to recognize the host.

Please see http://compliance.usb.org/index.asp?UpdateFile=USBCV#71

if that doesn't work, please contact the USB-IF directly.
