2.3.3
Measuring the Power Density of Wide Band Digital Modulation Signal
This section describes how to measure the power density of a medium-speed radio frequency LAN in a
frequency band of 1 MHz.
Measurement conditions: The wide band digital modulation signal(16bps, BPSK) to be measured has a
frequency of 2.45 GHz and a level of +10 dBm.
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 as shown in Figure 2-88.
Figure 2-88 Setup for Measuring the Total Power
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.
Setting the measurement conditions
This changes the analyzer settings so that the input signal is displayed more clearly.
5.
Press FREQ, 2, ., 4, 5 and GHz.
A center frequency of 2.45 GHz is set.
