Command Descriptions
Arguments
<Block> or <QSt
ring>
is a complete sequence of program messages.
The messages must contain only valid commands that must be separated by
semicolons and must follow all rules for concatenating commands (See page 2-4,
Concatenating Commands.). The sequence must be ≤80 characters. <Block>
format is always returned as a query response.
Examples
*DDT #217ACQuire:STATE RUN<EOI> specifies that the acquisition system will
be started each time a *TRG command is sent.
DESE
Sets and queries the bits in the Device Event Status Enable Register (DESER).
The DESER is the mask that determines whether events are reported to the
Standard Event Status Register (SESR), and entered into the Event Queue. (See
page 3-1, Status and Events.)

Arguments
<NR1> is an integer v alue in the range from 0 to 255. The binary bits of DESER
are set according to this value. For example, DESE 209 sets the DESER to the
binary value 11010001 (that is, the most significant bit in the register is set to 1,
thenextmostsignificant bit to 1, the next bit to 0, and so on).
The power-on default for DESER is all bits set to 1 if *PSC is 1. If *PSC is 0, the
DESER maintains its value through a power cycle.
NOTE. Setting DESER and ESER to the same value allows only those codes to be
entered into the Event Queue and summarized on the ESB bit (bit 5) of the Status
Byte Register. Use the *ESE command to set ESER. For more information on
event handling, refer to the Status and Events chapter.
Examples
DESE 209 sets the DESER to binary 11010001, which enables the PON, URQ,
EXE, and OPC bits.
DESE? might return the following string DESE 186 , showing that DESER
contains the binary value 10111010.
