Description
This softkey displays the latched status of the follo wing fault
messages.
EEROM FAIL Indicates that the EEROM (electrically erasable
read only memory) has failed to store data properly
.
Whenever any data is stored in EEROM, the
integrity of the data is checked (read back and
compared to the data in RAM).
The EEROM is the main storage lo cation for
calibration data. If this fault is indicated, the presen
t
calibration data may be lost.
PWRON FAIL Indicates that the test of the processor, R
OM, RAM
and I/O system p erformed at power-on has failed.
The front panel INSTR CHECK LED lights. Initiate
a full self-test to gather more information if this fault
is indicated.
CALCO FAIL Indicates that the internal calibration data has b een
defaulted either delib erately or due to an EEROM
failure.
PLLZERO
FAIL
Indicates a phase lo ck lo op error caused by either a
hardware failure or misadjustment.
PLLWAIT
FAIL
Indicates a phase lo ck lo op error caused by either a
hardware failure or misadjustment. Initiate a full
self-test to gather more information if this fault is
indicated.
FNXFER
FAIL
Indicates that the transfer of fractional-N data
has failed. Initiate a full self-test to gather more
information if this fault is indicated.
