System-Related Operations
This section gives information on topics such as power-down recall,
self-test, error conditions, and front-panel display control. This
information is not directly related to waveform generation but is an
important part of operating the function generator.
Power-Down Recall Mode
When power is turned off, the function generator automatically stores
its state in memory location “0”. You can configure the function
generator to automatically recall the power-down state when power is
restored. The recall mode is
disabled when the function generator is
shipped from the factory.
The power-down recall mode can be set from the front-panel only.
•
When the recall mode is disabled (factory setting), the function
generator powers up in its default configuration (see page 123).
When the recall mode is
enabled , the function generator powers up
in the power-down configuration.
•
The power-down recall setting is stored in non-volatile memory,
and does not change when power has been off or after a remote
interface reset.
•
The power-down recall mode “remembers” the function (including
arbitrary waveforms), frequency, amplitude, dc offset, duty cycle,
as well as any modulation parameters.
•
Any arbitrary waveforms downloaded to “
VOLATILE
” memory are not
remembered. However, if an arbitrary waveform is being output
from
non-volatile memory when the state is stored, the waveform
data is stored. The stored waveform is output when the instrument
state is recalled.
•
Front-Panel Operation :
2: POWER ON (SYS MENU)
To enable the recall mode, select the “
LAST STATE
” choice.
To disable the recall mode, select the “
DEFAULT
” choice.
