WARNING The detachable power cord is the instrument disconnecting device. It disconnects the
mains circuits from the mains supply before other parts of the instrument. The front panel
switch is only a standby switch and is not a LINE switch (disconnecting device).
NOTE There are no replaceable fuses in the mains input or within the power supply assembly.
IMPORTANT Keysight personnel: after calibration is completed, attach four "calibration void if seal
broken" stickers to the PNA as shown in
