Hi,

I've encountered a problem when tried to clear the limit table in VEE using command ":CALC1:LIM:DATA 0", there was a error message “Numeric data not allowed” shown on NWA. But sometimes it worked successfully.
The NWA is E5070B with firmware revision A.06.50. As the command works sometime, so I think it shouldn't be the problem of the old firmware revision.
Can any help me on this?
Thanks a lot!

No one else has this question

Hi,

Can you share the block of code that is sending the command? It will be easier that way.

Hi,
I've attached both the VEE code and NWA screenshot in this link view.

Thanks!

Hi,

I have not program using an NA before. However, here is my thoughts. Which command is giving the error? ":CALC1:LIM:DATA 0" or "":CALC1:LIM:DATA 1xxxxxxx". To confirm, I would suggest to query SYST:ERR? after ":CALC1:LIM:DATA 0" and "":CALC1:LIM:DATA 1xxxxxxx". I have a sample attached below:
e5070.vee

Here could be other possiblity:
1. The instrument is busy doing some thing maybe sweep or etc, then the command (or some parameter) in ":CALC1:LIM:DATA 0" or "":CALC1:LIM:DATA 1xxxxxxx" is not acceptable by the instrument.
2. Any delay required in between ":CALC1:LIM:DATA 0" or "":CALC1:LIM:DATA 1xxxxxxx"?

With my zero experience with NA, I hope my comment is helpful

Attached is the screenshot when using your sample code. The error code is -128 as you can see. So what does it mean, is it just like the error message on the NA?

Hi Ulf,

The message shows in both conditions no matter limit lines exist or not. And i've upgrade the firmware to latest one but still the same.

I'm really really frustrated. Is it possible for any of you try this code on your ENA?

It run well at my side using E5071B with firmware A.06.51. See attached result (I need to send ":CALC1:PAR1:SEL" instead of ":CALC1:PAR2:SEL"). Could that be your other program setting that caused it? I couldn't find any E5070B here, so no way to try out. I would recommend to contact Agilent NA support personnel for further details. Sorry can't help much because I have zero experience with NA.

Hi all,

The problem has been solved.

The reason that i got the error message in certain condition is i used command to changed the data reading format(eg."":FORM:DATA REAL")in preceding VEE code. The format must be changed back to the default ASCII format to avoid this problem as far as i know for now.

Thanks for all your great support and assistance again!
