Thanks, Simon. I looked in MAX & can see the driver tkds30xx. I can select the different tabs at the bottom for configuring the driver, but I'm not sure how to configure it.
When I open SignalExpress & add a step to acquire signals, I can create a new IVI session. I use TDS3054B as the session name. Under the Resource Descriptor, I see the scope listed as GPIB0::1::INSTR, same name as in MAX. But when I try to select an instrument driver, all the drop down list has is a 'check mark'. It won't let me select it. If I push OK, it gives me an error when I try to run the step:
"ivi_IviScope Initialize With Options.vi<ERR>
Driver Status: (Hex 0xBFFA1207) Primary Error: (Hex 0xBFFA1207) The item does not exist in the collection."
Do I just have the driver configured wrong? Am I missing something esle? I tried downloading SignalExpress 2.5, but once it downloaded, I got an error when I tried to run the executable:
"Zip file is damaged, truncated, or has been changed since it was created. If you downloaded this file, try downloading again."
I tried again, but got the same error!!

Thanks, Kent. Here's the answer to your questions:
1. I'm currently using SignalExpress v2.0.0
2. No. I can't select any driver in the Create New IVI Session dialog box... All that there is to choose from is a "check-mark" & I can't even select that!
3. No. I can't edit the Resource Descriptor for a current IVI sessions. When I go to IVI session name & choose
edit/delete session, the dialog box doesn't show any IVI sessions available! I choose done & the box closes
and "tkds30xx is loaded in the IVI session name box, but still get an error:
Error -1074130425 occurred at ivi_IviScope Initialize With Options.vi
Possible reason(s):
Driver Status: (Hex 0xBFFA1207) Primary Error: (Hex 0xBFFA1207) The item does not exist in the collection.
Elaboration: tkds30xx
4. No. The file I downloaded is labeled "SigExpTek25.exe". I will download this file & try again...

Thanks again, Kent.
The article helped some, but I still don't have it working...
In MAX, under the IVI Drivers >> Logical Names, I have the name MyScope. For the General tab, I have the Driver Session listed as tkds30xx & a Description "TDS3054B oscilloscope".
In MAX, under the IVI Drivers >> Driver Sessions >> tkds30xx >> General tab, I have the following:
Initialization Options enabled: Cache, Range Check, Query Instrument Status; Simulate With: Don't Simulate; Driver Setup: tkds30xx; Description: TDS 3000 Series
In MAX, under the IVI Drivers >> Driver Sessions >> tkds30xx >> Hardware tab, I have the following:
Hardware Assets: Name - TDS3054B (checked); Resource Descriptor - GPIB0::1::INSTR
In MAX, under the IVI Drivers >> Driver Sessions >> tkds30xx >> Software tab, I have the following:
Software Module: <None>; my only choices are <None> or NIDMM.
In MAX, under the IVI Drivers >> Driver Sessions >> tkds30xx >> Virtual Names tab, I have the following:
Virtual Name: CHANNEL1, CHANNEL2, CHANNEL3, CHANNEL4; Physical Name: CH1, CH2, CH3, CH4
In MAX, under the IVI Drivers >> Driver Sessions >> tkds30xx >> Initial Settings tab, I have nothing.
In LabVIEW SignalExpress, I go to Add Step >> Acquire Signals >> IVI Acquire >> IVI Scope Acquire. The Step Setup box is displayed. On the Configuration tab >> Device section >> IVI session name, I select Create New... Another dialoge box opens with an IVI session name in it. I change it to MyScope (same as in MAX), choose the Resource Descriptor GPIB0::1::INSTR (same as in MAX), but can't select an instrument driver. The only thing available under Instrument driver is a check mark. I can't select it for some unknown reason. I hit the OK button & the box closes, returning to the Step Setup screen. I try to run the step once & get an error stating:
"ivi_IviScope Initialize With Options.vi<ERR>
Driver Status: (Hex 0xBFFA1207) Primary Error: (Hex 0xBFFA1207) The item does not exist in the collection.
Elaboration: tkds30xx"
Back to square 1...

OK. I'm getting somewhere...
I downloaded the driver again. This time, I think I got the right one! Simon's link to the ni.com site showed 2 download links, one for CVI & one for LabVIEW 7.1. I downloaded & installed the one for LabVIEW 7.1, then opened SignalExpress. The Step Setup box had more options this time & things were clicking...
BUT... when I hit Run or Run Once, I got nothing on the Data View screen. Soon another error message came up:
"Timeout.
<ERR> Driver Status: (Hex 0xBFFA2003) Max Time exceeded before operation completed."
Any suggestions?

OK. I got SignalExpress working... sort of!
I can talk to the scope & see it recording live data from a signal generator connected to Ch1. Adjusting the controls on the signal generator shows a change in the Data View on SignalExpress. That part works, but only when I push Autosetup in SignalExpress. The scope chatters, then I see a waveform on the scope that matches the waveform in the Data View of SignalExpress. If I try running the step w/out pushing Autosetup, I get a timeout error:
"Timeout.
<ERR>Driver Status: (Hex 0xBFFA2003) Max Time exceeded before operation completed."
When I make changes to the Configuration tab of the Step Setup box, SE comes back with the same error...
That's as far as I can get. Any other changes give me the same error...
Any suggestions?
