Power On Application - Keysight x-series User Reference Manual

An instrument can never power up for the first time in Last.
If line power to the analyzer is interrupted, for example by pulling the line cord plug or by switching off
power to a test rack, Power On Last State may not work properly. For proper operation, Power On Last
State depends on you shutting down the instrument using the Standby key or the SYSTem:PDOWn SCPI
command. This will ensure the last state of each mode is saved and can be recalled during a power up.

SYST:PON:TYPE LAST
Power on Last State only works if you have done a controlled shutdown prior to powering on in Last.
If a controlled shutdown is not done when in Power On Last State, the instrument will power up in
the last active mode, but it may not power up in the active mode's last state. If an invalid mode state
is detected, a Mode Preset will occur. To control the shutdown under remote control use the
:SYSTem:PDOWn command.
Last State
It is no longer possible to power-up the analyzer in the last mode the analyzer was running with that
mode in the preset state. (ESA/PSA SYST:PRESET:TYPE MODE with SYST:PON:PRESET) You can
power-on the analyzer in the last mode the instrument was running in its last state (SYST:PON:TYPE
LAST), or you can specify the mode to power-up in its preset state (SYST:PON:MODE <mode>).
