Status Registers
Use Status Registers to Determine the State of Analyzer Events and Conditions
Bit descriptions in the Questionable Status Calibration Condition Register are
given in the following table.
Bit Decimal
Value
Description
00Reserved: This bit is not used by the analyzer, but are for
future use with other Agilent products.
12Reserved: This bit is not used by the analyzer, but are for
future use with other Agilent products.
24TG Align Failure: A 1 in this bit position indicates that a
failure has occurred while trying to align the tracking
generator (TG).
38RF Align Failure: A 1 in this bit position indicates that a
failure has occurred while trying to align the RF section.
416IF Align Failure: A 1 in this bit position indicates that a
failure has occurred while trying to align the IF section.
532LO Align Failure: A 1 in this bit position indicates that
a failure has occurred while trying to align the local oscillator
(LO).
664ADC Align Failure: A 1 in this bit position indicates that
a failure has occurred while trying to align the
analog-to-digital converter (ADC).
7128FM Demod Align Failure: A 1 in this bit position
indicates that a failure has occurred while trying to align the
FM demodulation circuitry.
8256Misc/Sys Align Failure: A 1 in this bit position
indicates that a failure has occurred while trying to align the
quasi-peak detector.
9512Unused: This bit is always set to 0.
10 1024 Tracking Peak Needed: A 1 in this bit position indicates
that a tracking peak needs to be performed (the tracking
generator is in operation). (Agilent EMC models E7402A,
E7403A, E7404A, and E7405A, with Option 1DN, Tracking
Generator, only).
11 2048 Align RF Skipped: A 1 in this bit position indicates that
the alignment of the RF section was skipped, perhaps due to
an external 50 MHz signal having been detected.
12 4096 Align RF Now Needed: A 1 in this bit position indicates
that the RF section needs to be aligned.
13 8192 Reserved: This bit is not used by the analyzer, but is for
future use with other Agilent products.
