ESG config frequency significant digit error

I'm using a signal generator, Agilent ESG series, when you physically type in the frequency into the generator you can type up to 9 significant digits; however, when using the "config frequency" VI it will truncate anything over 7 significant digits. Is this a problem with the amount of variable space with the VI or does it sound like an error on my part?

It depends on the variable representation chosen for the device driver.

If the low level driver call (deepest level you can get by opening sub VI's) uses the same representation as the VI,  you cannot change it.
If the low level driver call uses a representation that can hold a larger number you can change it.

What andre.buurman@carya said is correct.  Check all the properties of all the controls you can change to make sure they are what you want.  Right click on the control and go to "Properties".  Then select the "Display Format" tab.  Make sure this it is set the way you want.  Also, check the Increment is not set to "coerce to nearest" on the "Data Entry" tab.
 
Hope this helps!
