tktds1k2k_ConfigureChannel() does not recognize CH3 as a valid choice.

[LByrd]

I am using a Tektronix TDS2024 4-channel scope. Although able to use channels 1 and 2, trying to use channel 3 produces a non-fatal run-time error in tktds1k2k.c line 878, col 5 of
"IVI_SetAttributeViBoolean:(return value==-1074135008)
0xbffa0020
Channel or repeated capability name specified is not valid for the instrument."

drivers are:
tktds1k2k.fp is dated 9-29-03, 9:01 AM
IVI version is 2.1
NI-488.2.10
NI-VISA 3.0.1

Any help or suggestions? Does this driver really support more than two channels?

Thanks.

Hi,
The driver does support the following models:
1002,1012,2002,2012,2014,2022,and 2024.

On initializing the driver, the default setup taken is for the model 1002 which has 2 channels.

To initialize the driver for the 2024 model, you need to specify the model number in the OptionString parameter of the InitWithOptions functions.
Example: "Simulate=0,RangeCheck=1,QueryInstrStatus=1,Cache=1,DriverSetup=Model:2024"

This is also detailed in the function panel help for the OptionString.

Hope this solves your problem.

Instead of using the option string, you can enable the identification query on the Initialize function.
