2 Operating Your Frequency Counter
92 Keysight 53150A/151A/152A Operating Guide
Using Power Correction
The Power Correction function in the main Menu allows you to set the Counter to
automatically compensate for power loss (or gain) that occurs in the test
configuration, such as attenuation resulting from cable impedance. You can
choose from nine power-correction profiles that are stored in nonvolatile memory,
and you can modify the contents of these profiles.
Each profile is defined by two to ten data points (a data point consists of a loss
value and a frequency value). When Power Correction is enabled, the Counter
automatically adds a correction to the power reading (determined from the data
points in the profile) that compensates for the loss (or gain) at the frequency being
measured. When a measured frequency does not match any of the frequency
values defined in the currently selected profile, the Counter interpolates for the
measured frequency to determine the appropriate loss value to add to the power
measurement.
A minimum of two valid data points is required for Power Correction; you can
enter up to ten data points in each power-correction profile. Each of the
power-correction profiles initially contains two valid data points—0.0 dB loss at
1 GHz, and 0.0 dB loss at the highest frequency the Counter can measure (20 GHz
for the 53150A, 26.5 GHz for the 53151A, or 46 GHz for the 53152A). The
remaining eight data points contain values of 0.0 dB loss at 0.0 GHz. When
entering data, you can change the values in an existing data point or enter new
values in a data point that currently has zero values. The data points are
automatically sorted into order by frequency as you finish entering each one.
