Page 5: Introduction
1 Introduction If the [COMMAND MONITOR] function is used at the time of program creation, commands and responses will be conveniently displayed on the measurement screen. For information on the [COMMAND MONITOR] function, see the instruction manual of the instruments. Various messages are supported for controlling the instrument through the interfaces. - Page 6 Response Messages When a query message is received, its syntax is checked and a response message is :SYSTem:HEADer generated. command determines whether headers are prefixed to response messages. :RANGE 200pA Header ON 200pA Header OFF (The current measurement range is 200pA) At power-on, Header OFF is selected.
- Page 7 Message Terminators This instrument recognizes the following message terminators (delimiters): • • CR+LF Also the terminator for response messages is as follows: • CR+LF (USB, RS-232C, GP-IB) • LF (Only GP-IB) Separators (1) Message Unit Separator Multiple messages can be written in one line by separating them with semicolons “;” :RANGe 200pA;*IDN? •...
