INTERNAL STATE CHANGE ENABLE REGISTER (INE)
INE allows one or more events in the Internal State Change Status Register to be reported to the INB
summary bit in the STB.
Modify INE with INE and clear it with INE 0, or after power-on. Read it with INE?.
COMMAND ERROR STATUS REGISTER (CMR)
This register contains the code of the last command error detected by the oscilloscope. List these error codes
using CMR?.
Read CMR with CMR?. The response is the error code. Clear the register with a CMR? or ALST? query, a *CLS
command, or with power-on.
DEVICE DEPENDENT ERROR STATUS REGISTER (DDR)
DDR indicates the type of hardware errors affecting your instrument. Individual bits in this register report
specific hardware failures. List them using DDR?.
Also read this register using the DDR? query. The response is the binary weighted sum of the error bits. Clear
it with another DDR? or with ALST?, a *CLS command, or with power-on.
EXECUTION ERROR STATUS REGISTER (EXR)
EXR contains the code of the last execution error detected by the oscilloscope. List these error codes with
EXR?.
Read the register, again using the EXR? query. The response is the error code. Clear with another EXR? or
with ALST?, a *CLS command, or with power-on.
USER REQUEST STATUS REGISTER (URR)
Finally, URR contains the identification code of the last menu button pressed. List these codes with URR?.
Read URR using the same query. The response is the decimal code associated with the selected menu button.
And clear the register with another URR?, or with ALST?, a *CLS command, or with power-on.
