ASCII String Parameters
String parameters can contain virtually any set of ASCII characters. A string must begin and end with
matching quotes; either with a single quote or a double quote. You can include the quote delimiter as
part of the string by typing it twice without any characters in between. The following command uses a
string parameter:
CALibrate:DATE "12/12/12"
Arbitrary Block Program or Response Data
Definite-length block data <Block> allows any type of device-dependent data to be programmed or
returned as a series of 8-bit binary data bytes. This is particularly useful for transferring large
quantities of data or 8-bit extended ASCII codes.
Device Clear
Device Clear is an IEEE-488 low-level bus message that you can use to return the instrument to a
responsive state. Different programming languages and IEEE-488 interface cards provide access to
this capability through their own unique commands. The status registers, the error queue, and all
configuration states are left unchanged when a Device Clear message is received.
Device Clear performs the following actions:
l
If a measurement is in progress, it is aborted.
l
The instrument returns to the trigger idle state.
l
The instrument's input and output buffers are cleared.
l
The instrument is prepared to accept a new command string.
The ABORt command is the recommended method to terminate an instrument
operation.
