Operating the Meter Using the Computer Interface
Computer Interface Command Set
5
5-19
6 will always be zero.) Convert the returned value to binary to determine the status of
register bits.
EXAMPLE EXPLANATION
*SRE? Reads the value of the SRE Register. Assume "32" is returned.
Converting 32 to the binary 00100000 indicates that bit 5 in the SRE
is set to 1.
Computer Interface Command Set
The remainder of Chapter 5 describes the RS-232 and IEEE-488 computer interface
commands. RS-232 and IEEE-488 commands are identical, except where indicated.
These commands, grouped by related function, are listed in the tables that follow. A
parameter that must be supplied by the user, or a string returned by the meter is enclosed
in angle brackets (e.g., <value>).
• IEEE-488 Capabilities and Common Commands (Tables 5-8 and 5-9)
• Function Commands and Queries (Table 5-11)
• Function Modifier Commands and Queries (Table 5-12)
• Range and Measurement Rate Commands and Queries (Table 5-13)
• Measurement Queries (Table 5-14)
• Compare Commands and Queries (Table 5-15)
• Trigger Configuration Commands (Table 5-16)
• Miscellaneous Commands and Queries (Table 5-17)
• RS-232 Remote/ Local Configuration Commands (Table 5-18)
IEEE-488 Capabilities and Common Commands
The meter supports the IEEE-488 capabilities shown in Table 5-8.
Table 5-9 Summarizes the IEEE-488 Common Commands.
