Use Cable Correction
Cable Correction allows you to adjust the output power of the 2500B to compensate for losses created by connecting
devices such as RF cables, connectors and other RF devices. The maximum correction is less than 10 dB, and depends on
the absolute power output level. The power correction cannot exceed the maximum or minimum power output within a
given setting of the step attenuator.
This function creates a user correction table of 1001 points for the frequency range of the unit. The power output for
frequencies between the correction points is determined using a linear interpolation algorithm for the first frequency
points above and below the selected frequency.
NOTE:
The example procedure in this section uses specific parameters to illustrate how to setup the 2500B. You can use
this procedure for real-life situations by simply changing the parameters to fit your needs.
