Percent or dB

Display resolution

Selectable resolution of 1.0, 0.1, 0.01, 0.001 dB

in logarithmic mode, or 1 to 4 significant digits in

linear mode.

Offset range

± 100 dB in 0.001 dB increments, to compensate

for external loss or gain

Video bandwidth

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.
