Attenuator calibration absolute error from DC logger calibration.
Fidelity error from DC logger calibration.
Fidelity offset error from DC logger calibration.
Fidelity offset unstable from DC logger calibration.
Fidelity gain error from DC logger calibration.
ADC timeout errors occur if the A2 controller assembly frequency
counter is faulty. Refer to Chapter 8, "ADC/Interface Section."
Hardware/firmware interaction; check other errors.
Hardware/firmware interaction; check other errors.
ADC input is outside of the ADC range.
Microprocessor is not receiving interrupt from ADC.
Faults on the A2 controller assembly can cause these errors. Refer
to Chapter 10, "Controller Section." Although some of these errors
might result in a blanked display, it is possible to read these errors
over HP-IB. Refer to "Troubleshooting to a Functional Section" in this
chapter.
The EEROM on A2 is used to store data for frequency response
correction, elapsed time, focus, and intensity levels. Error codes from
700 to 703 indicate that some part of the data in EEROM is invalid.
An EEROM error could result from either a defective EEROM or an
