CMS54: Changing units for remote control

Question:

I have a GPIB interface and want to remote control with the CMS. My example is running, but some units such as MHz or dBm are not accepted although they are listed in the CMS manual. What is the reason for this?

Answer:

In most cases, the termination of the GPIB string is wrong. If you use the termination 0x0A, the GPIB program will run.
Example:
The command FREQUENCY:RF:TXTEST 200 KHZ works if the string is terminated by a new-line character (hex 0a). This means you have to write "FREQUENCY:RF:TXTEST 200 KHZ\n".
The termination character is necessary for all setting commands in the CMS with a specified unit.

For Rohde&Schwarz BASIC, you can use the IEC TERM 10 command.
