10. Configure the Power Meter to indicate readings in dBm. Enter the
The recommended Power Meter has Power Sensor calibration
factors stored internally in the sensor. Setting the input frequency in
the Power Meter automatically selects the appropriate cal factor for
the measurement. However, the Power Sensor may also be
accompanied by a table of calibration factors which must be applied
externally.
11. Allow the Power Meter reading to settle. Record the measured level in dBm
The Power Meter autorange boundary may coincide with a
measurement point. To avoid unwanted Power Meter autoranging,
manually lock the Power Meter range once the 100 kHz reading is
obtained and maintain the Power Meter range lock for all
subsequent frequencies at this amplitude.
