Recall
modified. In addition, you can use the Edit Register Names key under Save, State to enter custom names
for each register.
In products that run multiple instances of the X-Series Application, recalling the same register name on
each instance is a way to share setups between the instances.
Registers are shared by all modes, so recalling from any one of the registers will cause a mode switch to
the mode that was active when the save to the Register occurred.
Although these 16 registers are the only registers available from the front panel, there are 128 state
registers available in the instrument. Registers 17–128 are only available from the SCPI interface, using
the *RCL command.
After the recall completes, the message "Register <register number> recalled" appears in the message
bar. If you are in the Spectrum Analyzer Mode, and you are recalling a register that was saved in the
Spectrum Analyzer Mode, then after the recall, you will still be in the Recall Register menu. If the Recall
causes you to switch modes, then after the Recall, you will be in the Frequency menu.
If a requested register is empty an error is generated.

Selecting any one of these register keys causes the State of the mode from the specified Register to be
recalled. Each of the register keys annotates whether it is empty or at what date and time it was last
modified. In addition, you can use the Edit Register Names key under Save, State to enter custom names
for each register.
