Enable Registers.

The enable registers determine whether certain events are reported to the Status

Byte Register and SRQ. This oscilloscope has the following enable registers.

Event Status Enable Register (ESER)

OPERation Enable Register

z

QUEStionable Enable Register

When one of the bits of the enable registers is high and the corresponding bit in the

status register is high, the enable registers will perform a logical OR function, the

output that controls the set bit of the Status Byte Register is high.

Various commands set the bits in the enable registers. The following sections

describe the enable registers and the commands that set them.

Event Status Enable Register (ESER): The ESER controls which types of events

are summarized by the Event Status Bit (ESB) in the SBR. The bits of the ESER

correspond to the bits of the SESR.

Use the *ESE command to set the bits in ESER. Use the *ESE? command to read

it.

OPERation Enable Register: Even though the OPERation Enable Register is

present in this digital storage oscilloscope, the OPERation registers do not report

any conditions.

QUEStionable Enable Register: The QUEStionable Enable Register controls which

types of events are summarized by the QUES status bit in the SBR.
