Activating Optional Software
This procedure describes how to install and uninstall the optional
Power Analysis and other software modules that use a GW Instek
USB license key.
License keys can be uninstalled and transferred* to another
oscilloscope at anytime. A license key can only be used with one
machine at a time.
For more information, contact your local distributor or GW Instek
at www.gwinstek.com/ma[email protected]om.tw.

Uninstallation / Transfer of License Key
Background
License keys can be uninstalled and transferred to
another oscilloscope at anytime. Only one license
key can be used on one oscilloscope at a time.
When one of the optional software license keys
has been uninstalled, the license key is
automatically transferred back to the GW Instek
USB license key flash drive- ready to be installed
on another oscilloscope.

Set the Deskew
The deskew function is used to compensate for the propagation
delay between the oscilloscope and the probe. For power
measurements this is especially important as voltage and current
probes are often used in measurements and have differing
propagation delays.
Background
The deskew function allows the time delay
between voltage and current probes to be
equalized.
Panel operation
1. If necessary configure a channel as
a voltage probe and another
channel as a current probe.
See the user
manual.
2. Press one of the Channel keys that
was set as the voltage or current
probe.
CH1
3. Press Probe from the bottom menu.
4. Press Deskew on the side menu and
use the variable knob to set the
deskew time.
Alternatively, press Set to 0s to
reset the deskew time.
Typically, both channels should
line up with a common edge.
Range
-50ns~50ns, 10ps increments
5. If necessary, repeat the procedure for the other
channel.

Power Analysis
The Power Analysis software provides automatic measurement for
a number of advanced measurement types such as power quality,
harmonics, ripple and inrush current. The Power analysis software
is an optional software module. To install the optional software
module, please see page 5.
Power Analysis overview
Power Quality
Power quality measures the power of a signal from
the voltage and current measurement.
Harmonics
The harmonics function shows signal harmonics
up to the 400th harmonic. Harmonic tests can be
user defined and common harmonic standards
such as IEC 61000-3-2 can also be tested for.
Ripple
The ripple function automatically calculates the
ripple and noise of the waveform.
Inrush Current
The inrush function automatically calculates the
first peak and second peak inrush current.
