Overview
The E4990A allows you to save/recall the instrument state for each
channel independently. This function allows you to save the instrument
state of the active channel independently into one of the four registers (A
to D, volatile memory) and to recall the instrument state from the register
to restore it as the state of the currently active channel. As in the case of
saving the entire state of the instrument into a file, you can select items to
be saved from four kinds.
Since you can recall the instrument state for each channel that was saved
with this function from a different channel that the one used to save it, this
function is very useful for copying an instrument state between channels.
Unlike when saving the entire instrument state, the
instrument state for each channel is saved into volatile memory
instead of a file, so if you turn off the power, the state is lost.
Saving Instrument State for Each Channel
1. Press Channel Next (or Channel Prev) to activate a channel of which
the state you want to save.
2. Press Save/Recall > Save Channel.
3. Click one of State & Cal A to D, Cal Only A to D to save the
(instrument state and) calibration data of the active channel to the
specified register.
