Calibrating the RF Level of HP XXXXX RF ANALYZER;... The system measures the
amplitude of a 100 kHz tone with both the RF Analyzer and the HP
3561 A.
This insures
consistency between the two analyzers at 100 kHz.
Cause FIRST calibration PEAK voltage at mixer... During calibration of the Phase
Detector, the user is required to adjust the dc output of the phase detector to its maximum
and minimum peak.
Action:
Adjust frequency or phase angle to drive the phase detector output to the positive or
negative peak.
Cause SECOND calibration PEAK voltage at mixer... During calibration of the Phase
Detector, the user is required to force the dc output of the phase detector to its maximum
and minimum peak.
Action:
Adjust frequency or phase angle to drive the phase detector output to the
opposite peak.
Checking for HP3561A Noise Source... The noise source is being tested for proper output
level using the Performance Test technique described in the HP 3561A Service Manual. The
system also checks path attenuation in the HP 11848A.
Checking for overload... The system verifies that an overload condition does not exist when
in the Noise Monitor Mode.
Checking the PLL... The system verifies that the system is still phase locked.
CLEARING 0 TO 100 kHz. CALIBRATION DATA... This does not affect calibration data
stored on Mass Storage Media.
CLEARING 100 kHz. TO 40 MHz. CALIBRATION DATA... This does not affect calibration
data stored on Mass Storage Media.
CLEARING AUXILIARY 100 kHz. TO 40 MHz. CALIBRATION DATA... This does not
affect calibration data stored on Mass Storage Media (for caldata generated from Flatness
Performance Test).
Closing the Phase Lock Loop... This message notifies the user that the system is in the
process of closing the phase lock loop.
