:NRAM:ADDRess? DIAGnostic:NRAM:ADDRess? Returns the starting address of the non-volatile
User RAM segment allocated using DIAG:NRAM:CREate.
Comments • DIAG:NRAM:CREAte does not allocate the RAM segment until after a
subsequent re-boot. To get accurate results, execute
DIAG:NRAM:ADDRess? after the re-boot.

Comments • The RAM segment will be created only after the System Instrument has
been re-booted (cycle power or execute DIAG:BOOT).
• Based on the size specified, DIAG:NRAM:CRE rounds the size up to an
even value.
• NRAM will de-allocate a previously allocated RDISk segment.
• Using all of the available RAM (MAX) for the NRAM segment will limit
some functions such as IBASIC program space, instrument reading
storage space, and full functionality of the Display Terminal Interface.
• Use DIAG:NRAM:ADDR? to determine the starting address of the
RAM segment.
• Use DIAG:DOWNload, DIAG:UPLoad?, DIAG:PEEK, or
DIAG:POKE to store and retrieve information in the non-volatile RAM
segment.
• Use DIAG:NRAM:CRE? MAX to find maximum available segment size.
