Introduction
SCPI programming, optionally using a LAN connection is the way to
control the M8121A automatically.
Three LAN protocols are supported:
• VXI-11: The Visa Resource String is e.g.,
"TCPIP0::localhost::inst0::INSTR".
• HiSLIP: This protocol is recommended. It offers the functionality of
VXI-11 protocol with better performance that is near socket
performance. Visa Resource Strings look like
"TCPIP0::localhost::hislip0::INSTR". The correct resource string is
shown in the M8121A About Box.
• Socket: This protocol can be used with any I/O library or using standard
operating system socket functionality connecting to port 5025. Visa
Resource string looks like "TCPIP0::localhost::5025::SOCKET".
Command Line Arguments
Before sending SCPI commands to the instrument, the firmware
(M8121Firmware.exe) must be started. This can be done in the Windows
Start menu (All Programs >Keysight M8121 > Keysight M8121).
(See Communication
/FallBack).
Option
/Minimized
/Hide
/s socketPort
/t telnetPort
/i instrumentNumber
/AutoID
for details about /s, /t, /i, /AutoID, /NoAutoID,
Decsription
Start minimized.
Start without application window; only show notify icon.
Set the socket port at which the firmware waits for SCPI commands
Set the telnet port at which the firmware waits for SCPI commands
Set the instrument number (instN, hislipN) at which the firmware waits
for SCPI commands
Automatically select ports and number for the connections (default
behavior).
