2.3.1
Measuring Average Power of Digital Modulation Signal
This section describes the method for measuring the average power of digital modulation signal used in
PHS and so on.
Measurement conditions: The unit used in this measurement must comply with the PHS system and out-
put a frequency of 1917.950 MHz and a level of 10 dBm. The signal used must
be continuous.
Use appropriate parameter values to make the measurements shown below.
CAUTION:
The maximum amount of power that can be input to the
analyzer
is 30 dBm (1 W). When measur-
ing a signal power whose value exceeds this limit, connect an external attenuator so the power can-
not exceed 30 dBm.
Setup
1.
Connect the unit under test as shown in Figure 2-80.

Power on
2.
Turn the analyzer and the unit under test power on.
Setting the unit under test
3.
Activate the signal output for the unit under test.
Initialization
This resets the current settings to the factory defaults or user-defined presets.
4.
Press SHIFT and CONFIG(PRESET).
This sets the analyzer to its presets values.
