Making Measurements

Example 9: Adjacent Channel Power Measurement

Stepping Through a Basic ACP Measurement

In this example, we will be using a transmitter with a carrier frequency

of 300 MHz. We will deﬁne the signal that we examine has having a

channel bandwidth of 14.0 kHz and a channel spacing requirement of

20.0 kHz, as shown in Figure 2-53. For this example we will use the

calibrator as the signal source. You would normally provide a signal to

the spectrum analyzer either by connecting a radio directly, or by

coupling a signal from the radio via an antenna.

CAUTION The maximum input to the spectrum analyzer should not exceed +30

dBm (1 W) with greater than or equal to 10 dB attenuation.
