Evaluation Board User Guide
WAVEFORM SAMPLING
The Waveform Sampling window is available from the MENU
box. The Waveform Sampling window is shown in Figure 14.
To use the Waveform Sampling window, SPI must be selected
as the communication interface (see Figure 7).

The switch buttons in the ADE7953 Interrupts window allow
the individual interrupt enable bits to be selected. After the
appropriate interrupt enable bits are selected, they can be
written to the part by clicking Write IRQ Enable Register.
The lights represent the corresponding interrupt status registers.
These registers can be read and reset by clicking Read IRQ Status
or Read IRQ Status with Reset.
POWER QUALITY
The Power Quality window is available from the MENU box.
The Power Quality window is shown in Figure 16.
Figure 14. Waveform Sampling Window
This window allows raw waveform data to be captured and
displayed on a graph. To save the data to a file, click the Store
data to file? toggle switch and enter a destination file name in
the adjacent box.
ADE7953 INTERRUPTS
The ADE7953 Interrupts window is available from the MENU
box. The ADE7953 Interrupts window is shown in Figure 15.
Figure 16. Power Quality Window
The following features can be configured using the Power
Quality window:
• Peak detection
• Sag detection
• No-load detection
• Zero-crossing detection
• Power factor measurement
• Angle measurement
• Reverse power
The tabs in the Power Quality window are used to select
the appropriate feature. Each feature can be configured and
then written to the part by clicking WRITE. The ADE7953
Interrupts window shown in Figure 15 can be accessed from
the Power Quality window by clicking IRQ’s.
