Use
jog shuttle & SELECT
to turn ON/OFF Math1 or Math2.
•
When OFF is selected, standard waveform computation parameters can be assigned
to the computed waveform.
•
When ON is selected, power analysis parameters can be assigned to the computed
waveform.
Turn ON/OFF the assignment of the
power analysis parameters to the
computation waveform
Power analysis parameters can be
assigned to computation waveforms that
are turned ON.

Explanation
To compute power analysis parameters using the power analysis function (/G4 option), you
must turn ON the power analysis function, select the voltage probe attenuation, and select
the current-to-voltage conversion ratio of current probes. In addition, the waveform
computation setting must be turned ON (enabled) when performing waveform computation.
Turning ON/OFF the Power Analysis Function
Channels for applying voltage and current signals are predefined. The pairing of
channels is also predefined as shown below.

Analysis Parameters
CH1
Voltage
Measures power analysis parameters on the
CH2
Current
voltage and current applied to CH1 and CH2.
CH3
Voltage
Measures power analysis parameters on the
CH4
Current
voltage and current applied to CH3 and CH4.
CH5
Voltage
Measures power analysis parameters on the
CH6
Current
voltage and current applied to CH5 and CH6.
*
CH5 and CH6 can be used only on the DL7480.
You can select whether to perform power analysis (ON/OFF) for each channel pair.
OFF
Power analysis is not performed on the channel pair.
ON
Power analysis is performed on the channel pair.
