Problem with a labview driver for agilent spectrum analyzer e44xx

[celeocaddie@YAHoo.fr]

Hi !

I am using the Agilent Spectrum Analyzer E4446A (44GHz). I have installed the LabView Driver agesa_LV71.msi on my Windows XP PC.

Then I have configured MAX and try (with LabView 7.1) the example agesa Marker Peak Search Example.vi.

After some problems of strange "out of range", I have added a Property Node just after the VI agesa initialize to know the model number. Strangely it said me it was E4401B (1.53GHz)...

The resource descriptor is TCPIP::xxx.xx.xx.xx::INSTR. where xxx.xx.xx.xx is the IP Address of the Spectrum Analyzer E4446A.

Have you got any idea of why it doesn't answer E4446A ?

Hi Celine,

If you plan on using the specific driver only then there is no need to configure anything in MAX under the IVI Drivers section. The MAX configuration is needed only if you plan on developing your application using the IVI Class driver VI. In the example that you tried to use, make sure you use the correct VISA resource name for your instrument (configured under the Devices and Interfaces in MAX). You can also add the following string into the Option string control:

DriverSetup=Model:E4446A

In the driver, the default model is set to be E4401B and that is the model that will be returned in the simulation mode if the DriverSetup hasn't been specified. In general, if you enable IDQuery and don't pass DriverSetup, driver should automatically detect your instrument model.
