You can always change a control. Post this modified VI.

Since I don't have the instrument, you are going to have to do some basic troubleshooting. Namely, isolate which function generates the error. You can do it by single stepping through the program or opening each subVI and running them one by one.

this is the modiied VI.

I don't know what you mean by not being able to change the control. It works just fine.

So, the next step is for you to determine which function and set of values causes the instrument error. Post the results when you are done with that.

This is the latest modified copy of my program and i have run and tested the program and below are the problems that i have encountered.

the sweep section problems encountered 1) i cannot key in the value i want in the start/center and stop/span and as the results the values visible on the agilent is the DEFAULT value and the error shown on screen is "value out of range,set to limit" 2) as i key in my numbers, it changed to 2,699E+3 instead. 3) when i checked the blocked diagram there is no error thus i dont know what is the fault that not allowing it to key in numbers.

the source setup section problems encountered 1) again the value i select for example 3,000E+0 for the Level and "V" for the Level unit, it didnt telly with the agilent and so do the DC offset and sine frequency.

the input setup section problems encountered 1) whatever i select from the front panel, it didnt changed anything on the agilent and there is an error out. code -1074001663. source HP89400 Inputs Setup.vi. what does these mean actually?

thus these are the problems i encountered and i dont know if it is a silly mistake or whatsoever. so some kind explanation please. thanks.

Hi tyl,

'HP89400 Inputs Setup.vi' is one of those missing subvis and '-1074001663' is an user defined error code (atleast LabView didn't know this). So you should look inside the subvi where this error message comes from.

The same seems to apply for those other 'cannot key in values'-problem. In your vi I can change all values like described. But I cannot check whats happening inside those subvis... Maybe they do some range-checking?
Aahh, check those controls: in the data range property there are some ranges defined (from -897 to +2699). That's why you can't change this to values outside this range. Maybe there's a reason to do so?
