Send the command to download the data from memory.
:MEMory:DATA?
The stored measurement values are returned in response.
:MEM:DATA?
1, 290.60E-3, 1.3924E+0
2, 290.54E-3, 1.3924E+0
3, 290.50E-3, 1.3923E+0
4, 290.43E-3, 1.3923E+0
5, 290.34E-3, 1.3924E+0
END
The “END” character is sent as the last line of the data.
To download stored data one measurement at a time, send this command:
:MEMory:DATA? STEP
The instrument sends one stored data object and enters the wait state.
When the instrument receives an “N” from the PC or other device, the next
stored data object is sent.
Repeat until the last data object is downloaded.
When all stored data has been downloaded, the instrument sends an “END”
character.
:MEM:DATA? STEP

To clear the instrument's memory, send it the following command.
:MEMory:CLEAr
Unless the memory is cleared, measurement data continues to be stored
upon each trigger event.
• The instrument's memory storage capacity is 400 measurements. Be aware
that attempting to store more data (by applying a trigger) results in nothing
further being stored.
• Refer to Chapter 8 RS-232C/GP-IB/LAN Interfaces (Page 99),
for details about the communication methods and sending and receiving
commands.
• When the Memory function is enabled, auto-ranging is not available.
• Memory contents are cleared when performing the following operations:
When enabling the Memory function (off to on)
When changing the measurement range
When changing comparator settings
When sending the
:Memory:Clear command
When Reset is executed from the menu display
When sending
RST
When sending :SYSTem:RESet
When turning power on
