[FULL BAND (A, B, or C) Y/N]
Menu F4-1: The 8003 uses adaptive normalization. That is, the start and stop frequencies can
be changed within the frequency range for which the calibration was performed and the 8003
will automatically use the relevant calibration data.
Select Y to automatically set the start and stop frequencies to the full band of the sweeper dur-
ing the calibration process. Then any subsequent start and stop frequencies will use path cal
data.
Select N to store the path cal data for the user-selected frequency range only. In this case it
would be necessary to repeat the path cal if it was required to make measurements outside of
the original frequency range used for path cal.
[ THRU]
Menu F4: Performs a sensor through-path calibration in case it has not already been done on a
sensor currently being used, or in case it is desired to update the sensor path calibration data cur-
rently stored in memory. [
THRU ] brings up Menu F4-2 from where the sensor of interest can be
selected. A through-path calibration is performed and is stored in the same manner as either the
short or open path calibrations described previously.
[ FULL BAND (A, B, or C) Y/N]
Menu F4-2: Function the same as those in Menu F4-1.
[
CLR PTH CAL]
Menu F4: Accesses menu F4-3 wherein the desired sensor can be selected for the clearing of its
path calibration. When the sensor softkey is pressed, the instrument will initialize the specified sen-
sor’s path calibration to a 0 dBm trace which would have no effect if ratio’ed with any measure-
ment.
