lower case letters. A command may be used to either set a parameter or display
a parameter. If a command is sent with no right-side value, the current parame-
ter value will be returned. If the command is sent followed by an "=" character
and a valid value, the parameter will be set to that value.
The "tem" command is used to read the most recent measurement. It will re-
turn the channel from which the measurement was made immediately followed
by the ":" character and a space, the value of the measurement, which is 10
characters wide padded with spaces on the left and with the same resolution as
the displayed measurement, followed by a space, the unit character, and option-
ally, the time and date. The time and date options are set in the serial or
IEEE-488 setup screens or by using the appropriate interface commands.
The "new" command can be used to determine if a new measurement is avail-
able since the last one was read. The "new" command returns "NEW: 1" if a
new measurement is available and "NEW: 0" otherwise. This or any other com-
mand should not be sent at a rate higher than about five per second.
In the following list of commands, characters or data within brackets "[ ]" are
optional. A slash "/" denotes alternative characters or data. Numeric data, de-
noted by n, may be entered in decimal or exponential notation. Characters are
shown in lower case, however upper case may also be used. Spaces may be
added within command strings and will simply be ignored. A terminating car-
riage return or linefeed is implied with all commands. Each command descrip-
tion below is followed by an example of a command string the computer might
send to the 1575/1590.
