4530 Series RF Power Meter
Remote Operation
*ESE
Description:
Set or return the Standard Event Status Enable Register. The mask value in this register is
used to enable particular bits for generating a service request (SRQ) over the GPIB when
certain conditions exist in the Event Status Register. When a mask bit is set, and the
corresponding ESR bit goes true, an SRQ will be generated, provided the Event Status
Summary bit (ESB, bit 5) is enabled in the SRE register. No SRQ can be generated for that
condition if the mask bit is clear. See the
*ESR
command for bit assignments.
Syntax:
*ESE <n>
Argument:
<n> = 0 to 255
Valid Modes:
Any
*ESR
Description:
Return the current value of the Standard Event Status Register, then clear the register. This
register has bits assigned to a number of possible events or conditions of the instrument.
The register value may be read using this command, or may be used to generate a service
request (SRQ) over the GPIB when certain conditions exist. Individual bits may be enabled
or disabled for SRQ generation using the ESE mask (see
*ESE
command). The following
table shows the bit assignments in the Standard Event Status Register:
