Standard Event Status Register (SESR)

The Standard Event Status Register (SESR) monitors the following

oscilloscope status events:

•

PON - Power On

•

URQ - User Request

•

CME - Command Error

•

EXE - Execution Error

•

DDE - Device Dependent Error

•

QYE - Query Error

•

RQC - Request Control

•

OPC - Operation Complete

When one of these events occur, the event sets the corresponding bit in the

the bits set in this register generate a summary bit to set bit 5 (ESB) in the

Status Byte Register.

The contents of the Standard Event Status Register can be read and the

bit weights of all of the bits that are set at the present time.

Example The following example uses the *ESR query to read the contents of the

Standard Event Status Register.

10 OUTPUT 707;":SYSTEM:HEADER OFF" !Turn headers off

20 OUTPUT 707;"*ESR?"

30 ENTER 707;Result !Place result in a numeric variable

40 PRINT Result !Print the result

50 End

If bit 4 (weight = 16) and bit 5 (weight = 32) are set, the program prints the

sum of the two weights.
