Measuring reference trace... This message indicates that a reference path for a transfer
function measurement is in progress (Functional Checks).
Measuring the Phase Detector Constant... Measuring the Phase Detector Constant is part
of measurement calibration.
NO MARKED SPURS FOUND IN SPECIFIED RANGE... The system was unable to detect
any spurs in the specified range.
Calibr Process
is not
No Measurement Calibration is needed for the following measurement type: Noise
Measurement Using HP3561A only, and (Baseband Noise)...
applicable for the measurement type selected.
NON-CLEARABLE SRQ EXISTS ON... The Controller is unable to clear an SRQ on an
instrument. (Often caused by placing the HP 3561A into free-run, auto trigger mode.)
Action:
Abort the measurement and press PRESET on the HP 3561A.
NOTE:
A blank field refers to the currently defined 'MASS STORAGE IS' device... A
reminder that lack of an MSUS causes the system to look for files at the default drive location.
No test-result data exists in memory... The Computed Outputs functions are performed on
the result data currently in memory.
Action:
Load the desired Result File, or perform a New or Repeat Measurement.
Offset the source and reference signals by at least 1 Hz and not more than 1 or 20
MHz, or 100 kHz. Press proceed when ready... This is a prompt for the beatnote
calibration method.
Action:
Adjust the sources to obtain an offset frequency of > 1 Hz and < 100 kHz
(or 20 MHz if an RF analyzer is being used).
One moment please... The system is averaging the data taken for the low frequency spans.
Over-writing ()... The System is saving the file under the same name.
Phase Det. Constant: Momentary display of the Phase Detector Constant determined in the
measurement calibration.
