[:CONFigure]:VME:RECeive:ADDRess:DATA?
VINStrument[:CONFigure]:VME:RECeive:ADDRess:DATA? returns two values:
A24,offset. A24 indicates that the Agilent E1445A’s A24 address space should be
used for writing waveform segment, segment sequence, DAC, or phase deviation
data, and offset is the offset into the A24 address space to be written to. The offset
returned depends on which of the above operations is active when the
ADDRess:DATA? query is executed. If none are active, Error +1022, "VXI data
transfer bus not active" is generated.
Comments • For segment sequence and phase deviation data, the offset returned is the offset of
the first of the two words that must be written.
• Executable when Initiated: Yes

*RST Condition: The VXI data transfer bus is not active
Example Querying the A24 Address Space Offset
LIST:SEL ABC;DEF 100 Creates waveform segment.
ARB:DOWN VXI,ABC,100 Starts download to segment.
VINS:VME:REC:ADDR:DATA? Queries A24 offset for data writes.
[:CONFigure]:VME:RECeive:ADDRess:READy?
VINStrument[:CONFigure]:VME:RECeive:ADDRess:READy? returns two values:
A24,112. A24 indicates that the Agilent E1445A’s A24 address space when writing
waveform segment, segment sequence, DAC, or phase deviation data, and
112 is the
offset into the A24 address space to be checked.
Actually, this indicated Status Register need never be checked. The
Agilent E1445A will always handshake any data written to it; however, the data will
be ignored if none of the above operations are active. Nevertheless, bit 1 of the
Status Register indicates whether the Agilent E1445A is in the initiated state or the
idle state: 1 indicates initiated, 0 indicates idle. This may useful when writing DAC
and phase deviation data as it can be checked to indicate when these types of data
will be ignored.
