tion that can help locate discontinuities in a transmission line.
CL cannot be measured in the distance domain.
•
Power monitor measurements can be either absolute or rela-
tive to some base power level, and can be displayed in either
dBm or Watts. To allow measurement and display of power
levels above the unit’s specified input, the user may attenuate
the signal and enter the corresponding offset. The offset is
added to the measured input power prior to display. Finally, a
zero adjust function is provided to allow substraction of an in-
herent “noise” level prior to display.
CAUTION: The measurement system MUST be cali-
brated at the ambient temperature prior to making a
measurement. You must calibrate when the setup fre-
quency is changed. The instrument can store up to
two calibrations. These stored calibrations are inde-
pendent of any stored setups. When you recall a
stored setup, perform a new calibration or recall a
stored calibration.
Making Common Function Selections
