DELETE:WAVEFORM ALL
removes all the waveforms stored in reference memory.
DELETE:WAVEFORM REF2
removes the waveform stored at REF2.
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. For a
more detailed discussion of the use of these registers, see page 3–1.
Status and Error
*CLS, *ESE, *ESR?, EVENT?, EVMsg?, *SRE, *STB?
DESE <NR1>
DESE?
DESE
?
<Space> <NR1>
<NR1> is a value in the range from 0 to 255. The binary bits of the 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, the
next most significant bit to 1, the next bit to 0, etc.).
The power-on default for DESER is all bits set if *PSC is 1. If *PSC is 0, the
DESER maintains its value through a power cycle.
NOTE. Setting the DESER and the 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 the ESER. A discussion
of event handling begins on page 3–1.
DESE 209
sets the DESER to binary 11010001, which enables the PON, URQ, EXE, and
OPC bits.
