Query (Download) Memory Data
Syntax
Query
:MEMory:DATA? [STEP]
Response <Memory data No. (NR1)>,<Measured resistance (NR3)>,<Measured
voltage (NR3)>
Memory data values are returned as data objects.
If [STEP] is omitted, all memory data objects are returned continu-
ously.

Note
• Stored memory data objects are returned continuously, or one data object at a
time. The “END” character is returned as the last data object. When the “STEP”
parameter is specified, one data object is returned at a time. Sending “N” to the
instrument after receiving the data causes the next data object to be returned.
The memory index is an unsigned three-digit integer. Refer to “Measurement
Value Formats” for format details of returned measurement values.
• A terminator is appended to the end of each returned memory data object.
When sending “N” from the PC or other device, a terminator is required.
See " Message Terminators" (p.110).
• Measured values are stored in memory when pressing the TRIG key, applying a
signal to the TRIG
EXT I/O connector or sending the TRG command (while
the Memory function is enabled). Up to 400 data objects can be stored. When
the memory is full, additional measurement data is not stored.
• When the Memory function is enabled, auto-ranging is disabled.
