Measuring the Channel and Adjacent Channel Power
In the following example, the channel and adjacent channel power is first measured on a signal with a
level of 0 dBm at 800 MHz to IS95. Then the channel and adjacent channel power is measured on a
GSM signal at 935.2 MHz with fast ACP measurement (FAST ACP).
In addition, the limit test is activated.
