Instrument State Storage
You can store up to three different instrument states in non-volatile
memory. This enables you to recall the entire instrument configuration
with a single command from the remote interface or with just a few
key presses from the front panel.
•
Three memory locations (numbered 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.
•
You cannot recall the instrument state from a memory location that
was not previously specified as a storage location. For example, an
error is generated if you attempt to recall from memory location “2”
but have never stored to that location.
From the front panel, “
NOT STORED
” is displayed if nothing is stored
in the specified memory location. From the remote interface, a
+810, “State has not been stored” error is generated if nothing is
stored in the specified memory location.
•
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.
