Hi all 

I try to make a serial connection between Keysight 34970A to PC via RS232 the problem that i faced is that the COM port doesn't configurated in NI-MAX .

THANK YOU

Did you install NI-VISA?  Did you install the driver for the serial port?

I work with these all the time, here's some advice...

1. You still have to install HP/Agilent/Keysite "Connection Expert"
2. You also have to install both NI-VISA and NI-488.2
   
   1. NI-VISA will make Keysite VISA secondary
3. You have to install all the above along with the LabVIEW runtime on compiled EXE deployments too
4. Set up the instrument com settings on the instrument (baud rate, etc.)
5. Connect to the instrument using their "connection expert"
6. Then use those settings in NI-MAX to create a VISA alias for the instument
7. Now that VISA alias should show up in LabVIEW VISA I/O controls.

ONE more thing: The black serial cables that come with the 34970A are crap! The do not have the hardware handshaking lines inside. So the highest setting the instrument can run reliably using them is 9600 baud Xon/Xoff flow control.

Buy some "real" serial cables and that instrument has no problem running at 1115200 baud with RTS/CTS flow control.
