Figure 9-4. Fine Power Meter
Power in the fine power meter is calculated by squaring each I (I and Q for complex inputs) sample,
summing, and then integrating the summed-squared results into a 58 bit accumulator over a
programmable integration period.
The integration period is programmed into the 21 bit counter, in 8 sample increments. The power stored in
the 58-bit register is:
Power = [ (I*I) x (Nx8 + 3) ] for real inputs where N is the integration count.
Power = [ (I*I + Q*Q) x (Nx8 + 3) ] for complex inputs where N is the integration count.
The power meter operation can be optionally synced. If power meter syncing is enabled, it waits for a
programmable number of cycles after a valid sync, and then starts computation. If syncing is disabled, it
starts computation as soon as the power meter is enabled. Once the computation interval is completed,
the computed power is written to a set of serial interface registers, and the next computation interval
begins. The contents of these registers can be read out serially through SDOUT.
The process begins with a sync event starting the 9 bit delay counter. After (8xsync_delay + 4) samples,
the integration interval is started. Integration continues until the integration count is met, at which point the
58 bit integrator results are transferred to the read only register. A new measurement period will start at
the end of the interval period.
A more detailed diagram of the power meter is shown below (the I and Q are represented as 16-bit
numbers).
