102 ANAL YZER TYPE MISMA TCH
Indicates an invalid function was selected in the present measurement item. Change the
measurement item, or select a dierent function.
13 B A CKUP D A T A LOST
Data checksum error on the battery backup memory has occurred. W ait until the battery is
re-charged (approximately 10 minutes after turning the 4352B on).
0160 Block data error
The 4352B detected an invalid syntax in a block data element.
0168 Block data not allowed
A legal block data element was encountered but was not allowed by the 4352B at this point in
parsing.
51 Calibration Aborted
The FM deviation calibration in progress was aborted. This was probably caused by changing
the measurement parameters during the FM deviation calibration.
P erform the FM deviation calibration again.
100 CAN'T CHANGE- ANOTHER CONTROLLER ON BUS
The 4352B cannot assume the mode of system controller until the active controller is removed
from the bus or relinquishes the bus . See the 4352B GPIB Programming Manual.
144 CAN'T CHANGE NUMBER OF POINTS
The number of points in the spectrum measurement cannot be changed manually , except in
zero span.
