E1411 channels scanning

[michalkubik]

Hello

I have MUX E1460 connected over analog bus to DMM E1411B

when i bring DC voltages to channels 100 and 101 I can measure the voltage only by closing channel 100 make 1st measurement, open channel 100, close channel 101 and make 2nd measurement.

Here is code sample

MUX

Close (@10992)

Close (@100)

DMM

VOLT:DC?

MUX

Open (@100)

Close (@101)

DMM

VOLT:DC?

This works fine, but I would like to do it in one command by using port scanning

I found example in user manual and it should look like this (I suppose)

Close (@10992)

Close (@100)

Close (@101)

DMM

VOLT:DC? (@100,101)

problem is that last command returns me error

iberr = EABO

Just for info I'm using NI-488.2 Communicator for communication with both devices.

Thanks,

Michal

Hey Michal,

I see you are having some issues when trying to communicate with some Agilent hardware.  I also replied to your other thread that you have going and I am not exactly sure why you are getting the EABO error, but I think an NI SPY capture would help for troubleshooting.  If you could post an NI SPY capture for both sets of commands, then we can compare the two and see what is different.
