Bit Description
0, 1 Reserved. These bits are not used by the analyzer, but are for
future use with other HP products.
2 A 1 in this bit position indicates that a failure has occurred while
trying to align the tracking generator (TG).
3 A 1 in this bit position indicates that a failure has occurred while
trying to align the RF section.
4 A 1 in this bit position indicates that a failure has occurred while
trying to align the IF.
5 A 1 in this bit position indicates that a failure has occurred while
trying to align the local oscillator (LO).
6 A 1 in this bit position indicates that a failure has occurred while
trying to align the analog-to-digital converter (ADC).
7 A 1 in this bit position indicates that a failure has occurred while
trying to align the FM demodulation circuitry.
8 A 1 in this bit position indicates that a failure has occurred while
trying to align the quasi-peak detector.
9 Unused. These bits are always set to 0.
10 A 1 in this bit position indicates that a tracking peak needs to be
performed for the CAL OUTPUT (the tracking generator is in
operation).
11 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.
