Introduction
This chapter provides information on using the Anritsu Power Meter application with the MA24104A inline
high power sensor. It provides a description of the Graphical User Interface, various settings of the application,
basic procedures for Making Measurements, as well as information about Uncertainty of a Measurement.

Description
1
RF Input
2
Power ON/OFF
3
USB Mini-B Port (for connection with a PC or Anritsu Handheld instrument)
4
2-color LED (reports functional status of the sensor)

Note: When using battery power with the RS232 interface, the MA24104A enables an auto shutdown
(sleep) feature. If the RS232 bus is disconnected or becomes inactive, the power sensor shuts down
(sleeps) to preserve battery power. The sensor automatically powers up (wakes up) when the host is
reconnected or becomes active. Zeroing is then required before taking measurements.
