TDS

Hi

I am trying to read value(for ex: RMS,Amplitude...) from TDS 340A through serial comms.

Its working with GPIB,the commands i have used is MEASUREMENT:IMMED:Value?

Pls tell me how to measure the values through serial comms

Thanks

Sorry it is 430A,not 340A

If you can't get a reading, then there are several things you should check. First, try using Hyperterminal. If that works, then you may not be appending a termination character to your command in LabVIEW. If Hyperterminal does not work, verify that the com settings are correct and that you have the correct serial cable. If you have a null-modem cable, try using a straight through and vice versa. If that still does not work, verifyin the manual that the serial port can actually be used for remote control. Some instruments have a serial port but it is intended for other uses.

Thanks Dennis

I tried to download  a waveform from oscillscope through RS232,its working. Only thing is to do remote control, the programmers manual explains about the control commands for GPIB, there is no commands for RS232.

Thanks

If RS-232 is supported, then the commands are identical. The only difference would be the termination character (i.e. \r, \r, \r\n). If in fact you were able to get a waveform, then you were able to successfully send a command.
