Unsupportet modules by IVI driver for Agilent 3499A

[Tischi]

I have an Agilent 3499A switch/control system with N2266A MUX modules inside which I want to control by the IVI driver. I have found the information that this module is not supportet by this driver. The N2260A MUX module, which has the same signal topology is supportet by this driver. Isn't it possible to use this driver for the N2266A module too?

Hi,

may be there exist one way how you can use it.

For example if you have in slot1 N2267A, slot2 N2266A, slot3 N2270A etc.
you can initialize with DriverSetup option string:
DriverSetup:slot1=N2267A;slot2:N2260A;slot3=N2270A

or you can use this driver setup only for module N2266A: DriverSetup: slot2=N2260A. all other slots will be detected automatically.

instead of N2266A you shoul use N2260A.

N2260A can work in four modes:
a) a 80-channel 1-wire multiplexer (1)
b) a 40-channel 2-wire multiplexer (2)
c) two independent, 20-channel 2-wire multiplexer (2D)
d) a 20-channel 4-wire multiplexer (4)

If you would like operate with N2260A with configuration two independent, 20-channel 2-wire multiplexer you should use in driver setup
slot2=N2260A:2D etc. More details in FP panel of IniWithOptions function.

If you does not specify configuration, configuration 40-channel 2-wire multiplexer will be used as default.

Differencies should be only in channel characteristics. So driver does not return correct max switching current etc., but routing should be correct.

Let me know, if it is working. When this will work correctly, it should be easy add support of this module to the driver.

Hi Zdenek

Thank you for your answer but it seems that this way will not work with TestStand IVI steps.

I hope that it should be work. Specify DriverSetup in MAX. I tried in simulation mode(I dont't have instrument) in TestStand without any problem. so if the commands are same for both modules it should be work.

Max settings - in slot 1 is N2260A (or N2260A)
Max settings2 - in slot 1 is N2260A (or N2260A) with 4-wire configuration and in slot 2 is N2267A

Hi Zdenek

Now it works! I setup only the default 2-wire modes in MAX. If some test sequences require the 1-wire mode then I configure the modes with the "Edit IVI Tools Step" in TestStand and afterwards I can select the low and high channels separately.

Thanks,
Simon
