E4990A Help
256
A space (ASCII code: 32) is required between a command and its first
parameter. When sending several parameters in a single command,
separate each parameter with a comma (,).
Message including several commands
When sending 2 or more commands in a single message, separate each
command with a semicolon (;). The following example shows how to send
the *CLS command and the :SYST:PRES command in a single message
using VISA-COM.
Ana.WriteString "*CLS;:SYST:PRES", True
Remote Mode
The E4990A does not provide remote mode. Therefore, even if you send a
GPIB command, it never enters into the remote mode automatically. There
is no local key to release remote mode.
If you need to prevent misoperation during remote control due to entry
from the front panel or mouse, lock the input devices using the following
commands.
• :SYST:KLOC:KBD
• :SYST:KLOC:MOUS
