"Auto Save" can be used to automatically save a current waveform if it satisfies
specific conditions.

Note:
- During the processing for previously acquired waveforms, the data is not saved
even if the specified condition is satisfied.
- Depending on the File Type and Limit Count, the size or number of the files to
be saved increases.
2. Push the “Auto Save” ( red circle ) button on the lower left of the display.
The waveforms consistent with the trigger condition are stored up until
the Limit Count set on the “Configuration > Auto Save” window.
This number is counted up until the Limit Count.
The 5 files are created in this sample.
The icon shows the disk usage. When the
free space becomes 10% or less, the color
changes from green to red.

How to minimize the offset current
1. Perform “User Calibration”. The
offset current of the current
sensor will be minimized.
2. Perform a actual measurement
and fix the connection and the
CX3300 settings such as the
current range.
3. Perform a “Null” measurement.

3-1. Make a connection to prevent the current flow into the current sensor.
Note for connection:
- Connect either the (+) or (-) terminal of the current sensor to the stable voltage
on the DUT.
- Connect the ground lead to the circuit common of the DUT.
Remove the test lead
of the (+) terminal to
prevent the current
flow into the current
sensor

Passive Probe Interface Adapter (CX1151A) to the device.
1-2. Execute the measurement.
2. Settings
2-1. Click on the “Setting” icon.
2-2. The “Setting” dialog box opens.
2-3. Click on “Setting>Channels>Skew".
2-4. The Skew setup panel opens and the waveforms for the effective
channels are shown behind the “Setting” dialog box.
