Saving and
Recalling Data
The 222PS has memory to store saved waveforms and frontĆpanel
setups. Data in this memory remains as long as the instrument has
access to one of these power sources:
H a battery with a charge greater than 7.32ĂV (see page 3Ć35 for a
discussion of battery operation)
H line voltage coming through a power cord plugged into a wall
socket through the external AC adapter (see page 3Ć41 for a
discussion of line operation)
H power coming in from another external power source (see
pageĂ3Ć42 for a description of acceptable external power sources)
The instrument does not need to be on for it to access power for the
memory. However, if you turn off the instrument, disconnect it from any
external power source, and remove its battery, it will lose any data in
memory after 30 s.
Waveforms
A saved waveform is a record of a single acquisition cycle. Think of it
as a snapshot of a waveform. The 222PS lets you save up to four
waveforms in memory. It can recall these at any time.
Saving a Waveform
Use these steps to save a waveform.
ĂĂStep 1:ă Select the channel whose waveform you wish to save or,
if you wish, put the instrument in XY mode.
ĂĂStep 2:ă Using the selected channel, acquire and display the
waveform you wish to save.
ĂĂStep 3:ă Position the waveform where you wish it to be saved.
