4-202
The queue for the :KEY? query command can only hold one key-press. When :KEY? is sent
over the bus, and the Model 2001 is addressed to talk, the key-press code number for the last
key pressed (either physically or with :KEY) will be sent to the computer.
OUTPUT 716; ":syst:key 29"
OUTPUT 716; ":syst:key 16; key 16"
OUTPUT 716; ":syst:key 8; key 8"
:SYSTem:CLEar
:syst:cle
This action command is used to clear the Error Queue of messages.
OUTPUT 716; ":stat:cle"
:SYSTem::FETCh:FORMat <name>
<name> = SCPI
= FRESh
:syst:fetc:form <name>
:FETCh:FORMat? Query fetch format
Short-form format: :syst:fetc:form?
Response message: SCPI, FRES
This command is used to select the format for the :FETCh? signal oriented measurement com-
mand. With SCPI selected, :FETCh? will request the latest reading. With FRESh selected,
:FETCh? will request a fresh reading. See :FETCh? for more information.
At power-on, the fetch format will be set to FRESh, and all elements will be included in the data
string for each measurement conversion (see :FORMat:ELEMents).
Note that the fetch format is not affected by *RST or :SYSTem:PRESet. However, with the
SCPI format selected, *RST will set the :FORMat:ELEMent command for READing only.
Also not that the fetch format is not remembered by the *SAV common command.
