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, theerror queue, and all
configuration states are left unchanged when aDevice Clear message is received.
Device Clear performs the following actions:
If a measurement is in progress, it is aborted.
The instrument returns to the trigger idle state.
The instrument's input and output buffers are cleared.
The instrument is prepared to accept a new command string.
The ABORt command is the recommended method to terminate an instrument
operation.
Typical Command Processing Times
The table below documents some typical, average command processing times (milliseconds) for
various commands and queries. This can help you determine the impact of some common SCPI
commands on total test time.
The command processing time is the time until the next command is accepted. It does not include
hardware response time.
