READY STATUS REGISTER
The RPM4-AD contains an 8 bit Ready Status Register that reflects specific RPM4-AD
Q-RPT measurement ready events. Enabled events in this register will set or clear the RSB
bit of the Status Byte Register.

This register can be read using the
“*RSR?”
query, Each of these status bits can set the
RSB bit of the Status Byte Register, causing a SRQ to occur IF the RSB bit is enabled to do so.
The Standard Event Status Enable Register (
“*RSE”
program message ) determines which
of these flags are able to assert the RSB bit. The description of these bits are given as:
MEAS LO
Lo-RPT measurement ready Bit 6 (64)
Indicates that the Hi Q-RPT has completed a Q-RPT measurement.
NRDY LO
Lo Q-RPT pressure Not Ready Bit 5 (32)
Indicates that the Hi Q-RPT made a transition from
Ready
to
Not Ready
as
defined by the stability settings (see Section 3.2.4).
RDY LO
Lo Q-RPT pressure Ready Bit 4 (16)
Indicates that the Hi Q-RPT is
Ready
as defined by the stability settings (see
Section 3.2.4).
MEAS HI
Hi Q-RPT measurement ready Bit 2 (4)
Indicates that the Hi Q-RPT has completed a Q-RPT measurement.
NRDY HI
Hi Q-RPT pressure Not Ready Bit 1 (2)
Indicates that the Hi Q-RPT made a transition from
Ready
to
Not Ready
as
defined by the stability settings (see Section 3.2.4).
RDY HI
Hi Q-RPT pressure Ready Bit 0 (1)
Indicates that the Hi Q-RPT is
Ready
as defined by the stability settings (see
Section 3.2.4).
