Command execution time indicates the time for analyzing and processing long form com-
mands.
However, the command execution time for commands with data is the time described accord-
ing to the data format specified in the <data portion>, and for query commands it is the time
when the header is ON.
• Display delays may occur depending on the frequency of communication processes and
process contents.
• All commands except
TRG
and
:INT
are processed sequentially.
• In communications with the controller, time must be added for data transmission. GP-IB
transfer time depends on the controller.
The time for RS-232C transfers involving a total of 10 bits (the start bit is 1, data length is 8,
no parity, stop bit is 1) is shown below.
9600 bps: approximately 960 characters/s
• Wait until measurements stabilize after a change before using a setting command.
An error occurs when messages are executed in the following cases:
•
Command Error
When message syntax (spelling) is invalid. When the data format in a command or query is
invalid.
•
Query Error
When the response message exceeds 64 bytes
•
Execution Error
When invalid character or numeric data is present
