*SAV {0|1|2|3}
Store up to four different instrument configurations.
[ Stored in non-volatile memory ]
Four memory locations (numbered 0, 1, 2, and 3) are available to store
instrument configurations. The state storage feature “remembers” the
function (including arbitrary waveforms), frequency, amplitude,
dc offset, duty cycle, as well as any modulation parameters. To recall
a stored state, you must use the same memory location used
previously to store the state.
From the remote interface only, you can use memory location “0” to
store a fourth instrument configuration (you cannot store to this
memory location from the front panel). However, keep in mind that
memory location “0” is automatically overwritten when the power is
turned off.
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.
If you delete an arbitrary waveform after storing the state, the
waveform data is lost and the function generator will not output the
waveform when the state is recalled. The “
SINC” waveform is output
in place of the deleted waveform.
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.
Select the
POWER ON LAST STATE command from the SYS MENU to
enable the power-down recall mode. Select
POWER ON DEFAULT to
disable the power-down recall mode. See “Power-Down Recall Mode”
on page 109 for more information.
