4. Tap the Power Autoset button for each measurement and wait for the busy indicator to disappear. The instrument has now
been optimized for that power measurement.
NOTE.
■
In case of failure, the instrument displays a popup error message. See Errors and Warnings .
■
When different frequency signals are connected to different channels, Power Autoset uses the AC signal of the
lowest-numbered channel to evaluate and set up the instrument parameters. For example, If Channel 1 is connected to
a DC signal, Channel 2 is connected to an AC signal of 1 MHz, and Channel 4 is connected to an AC signal of 1 kHz,
then
Power Autoset uses Channel 2 (the first channel with an AC signal) to set up the instrument parameters.
Channel 4 may not be set up to see the minimum number of cycles properly; you may need to manually set the
Channel 4 parameters.
■
Power Autoset runs all parts of instrument Autoset, even if some parts have been disabled in the User Preferences >
Autoset panel. See
Autoset panel fields and controls on page 291 for more information on the Autoset function.
■
Power Autoset is available per measurement. You should run the Power Autoset for each measurement separately
when you add measurements, to ensure optimum power measurement setup for that measurement.
Power sequence setup button
Use this button to set the oscilloscope acquisition system for optimal measurement results for Turn On Time, Turn Off Time,
Input Capacitance, and Inrush Current power measurements.
NOTE. The Power seq setup button is available only for Input Capacitance, Inrush Current, Turn On Time, and Turn Off Time
power measurements.
Use the following steps to run a Power seq setup on applicable power measurements:
1. Add the supported power measurements to the Results bar.
2. Double-tap each Measurement badge and configure the measurement (input voltage sources, current sources, label name,
and so on).
3. Connect the input signals and set the instrument controls to display the source waveforms, and verify that there is no
clipping on the waveforms.
4. Tap Power seq setup button in the measurement configuration menu and wait for the busy indicator to disappear.
5. Follow the instructions on the Measurement badge to take the power measurement.
If you are measuring multiple outputs, the Turn On Time for each output is shown in the measurement badge. Short vertical
annotation lines on the waveforms mark the Turn On Time or Turn Off Time for each output.
NOTE. For Input Capacitance and Inrush Current measurements, you can tap the measurement Result badge to show the
Previous and Next navigation buttons. Use the navigation buttons to traverse between areas of interest on the waveforms.
NOTE. Tap Power seq setup whenever you change the measurement configuration to optimize the measurement for the
changed values.
