Measurements

CW Measurement The CW Measurement screen displays the carrier frequency and power of a continuous (non-pulsed) signal. The CW Power measurement offers a greater dynamic range than is available when making pulsed measurements.

CW Power is a broadband measurement. The CW Frequency measurement is obtained using a tuned, selective input. The RF analyzer should be set to within 500 kHz of the expected signal frequency.

In the GSM band, the value that is entered should be set to the nearest 100 kHz. Select CW MEAS in the cell control screen to gain access to the power measurements of the Agilent 8922M/S.

The CW measurements are made automatically when you access the screen.

The CW Frequency field (1), see Figure 2-15 on page 2-28, displays the carrier frequency of the signal and CW Power (2) shows the power of the carrier signal. It is also possible to display the difference between the measured frequency and the value selected by choosing CWFreqErr from field 1.

These measurements can be reset using MeasReset. Select Pwr Zero before power is applied to zero the power meter in the Agilent 8922M/S.
