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
Measurement ready (Bit 2)
Indicates that the PPCH-G has completed a Q-RPT measurement.
NRDY
Generation Not Ready (Bit 1)
Indicates that the PPCH-G made a transition from Ready to Not Ready as
defined by the control settings (see Section 3.2.2).
RDY
Generation Ready (Bit 0)
Indicates that the PPCH-G has reached a target pressure and is Ready as
defined by the control settings (see Section 3.2.2).
