Basic Operation
Using the Instrument State Registers
Recalling an Instrument State
Using this procedure, you will learn how to recall instrument settings saved to an instrument state register.
Refer to the
“Recalling an Instrument State for a Waveform File” on page 73
for recalling a waveform file
and associated signal generator settings.
1. Press
Preset
.
2. Press the
Recall
hardkey.
Notice that the
Select Seq
softkey shows sequence 1. (This is the last sequence that you used.)
3. Press
RECALL Reg
.
The register to be recalled in sequence 1 becomes the active function. Press the up arrow key once to
select register 1. Your stored instrument state settings are recalled.
Saving an Instrument State for a Waveform File
This procedure applies to the E4438C with Option 001/601 or 002/602 and demonstrates saving signal
generator settings associated with a waveform file.
NOTE
The save function saves only a reference to a waveform file name; no waveform data is
stored. Use Save function to save signal generator settings and use the Store function to
save waveform data.
Signal generator settings such as frequency, power, attenuator level, and so forth, are not saved when a
waveform file is saved. Signal generator settings, associated with the waveform file, must be saved to the
instrument state memory. If there is no waveform file in NVWFM, create one using the procedure,
Waveform Segments” on page 107
You can save signal generator settings, associated with a waveform file, so that when you load the waveform
from NVWFM and play it, the same signal generator settings can be recalled and re-applied to the waveform
file.
