Chapter 3 Features and FunctionsOutput ConfigurationInstrument State StorageYou can store up to three different instrument states in non-volatilememory. This enables you to recall the entire instrument configurationwith a single command from the remote interface or with just a fewkey presses from the front panel.œ Three memory locations (numbered 1, 2, and 3) are available to storeinstrument configurations. The state storage feature “remembers” thefunction (including arbitrary waveforms), frequency, amplitude,dc offset, duty cycle, as well as any modulation parameters. To recalla stored state, you must use the same memory location usedpreviously to store the state.œ You cannot recall the instrument state from a memory location thatwas not previously specified as a storage location. For example, anerror is generated if you attempt to recall from memory location “2”but have never stored to that location.3From the front panel, “NOT STORED” is displayed if nothing is storedin the specified memory location. From the remote interface, a+810, “State has not been stored” error is generated if nothing isstored in the specified memory location.œ Any arbitrary waveforms downloaded to “VOLATILE” memory are notremembered. However, if an arbitrary waveform is being outputfrom non-volatile memory when the state is stored, the waveformdata is stored. The stored waveform is output when the instrumentstate is recalled.œ If you delete an arbitrary waveform after storing the state, thewaveform data is lost and the function generator will not output thewaveform when the state is recalled. The “SINC” waveform is outputin place of the deleted waveform.69
