5 MHz (set by meter and is sensor dependent)
Note that the video bandwidth represents the ability of the power sensor and meter to
follow the power envelope of the input signal. The power envelope of the input signal is, in
some cases, determined by the signal’s modulation bandwidth, and hence video bandwidth
is sometimes referred to as modulation bandwidth. The PCIe x16 Gen 3 link between CPU
and backplane switch provides up to 16 GB/s theoretical, 14.2 GB/s practical.
Video bandwidth/dynamic range optimization
The power measurement system, comprising the sensor and meter, has its maximum
video bandwidth defined by the E9320 sensor. To optimize the system’s dynamic range
for peak power measurements, the video bandwidth in the meter can be set to High,
Medium and Low, as detailed in the following table. The filter video bandwidths stated in
the table are not the 3 dB bandwidths as the video bandwidths are corrected for optimal
flatness. Refer to figures 6 to 8 for information on the sensor’s peak flatness response.
A filter OFF mode is also provided.
