Hi all,

I'm working with a MSO6052a oscilloscoop. I need an accurate acquisition and i found a way to do this in the programmers guide for the 6000 series oscilloscoop. My scoop is doing something strange when i'm trying to access the :WAV:POIN:MODE and :SYST:PREC ( and a few others ) parameters . He is saying "undefined header" on the oscilloscoop screen. I double checked it but there is nothing wrong with the command ( i'm using LabVIEW 7.1 ). The firmware revision of the scoop is 02.02. I don't know if this is the most resent revision... I hope somebody can help me.

PS I used the ":WAVeform:POINts:MODE" page of the programming guide

Regards,
Joren Moelans

2.2 is beyond ancient. I recommend you go to www.agilent.com and download the latest firmware for your scope.
"Undefined header" is usually the scope's response to a syntax error in the incoming data stream. The old firmware
did have some GPIB issues.

Thanks,

I've updated the firmware and the commands are working. Now i have some issues with commands that were working on 02.02 version. I'm sending commands in a loop to perform a lot of measurements of the same interval ( ... start, wait untill acquisition is done, read out data, ... ). For this i'm using the :DIG command. But after a random times the loop, the scope says "query unterminated". This is strange because i'm sending the same commands as the execution of the loop iteration before... Now I'm trying to use the :SINGle command and this works better. Is there an explaination for this fault or does somebody can tell me what i'm doing wrong?

Regards,
Joren

"Query Unterminated" is a generic error that the scope throws when it cannot finish terminating the read of a command string.
Is your loop cycling faster than the scope can acquire and transmit data? There is a command buffer on the GPIB input that may
be over run by waiting commands.
