Measuring Power

	Measuring Power
	The Agilent 53150A/53151A/53152A can also measure signal power
	(in the same frequency ranges as for frequency measurements) on
	Channel 2. The power measurement, which is shown in a dedicated area
	of the display, includes a digital readout and an analog representation
	that is useful when peaking signals. The display can be configured to show
	power in units of dB, dBm, W, mW, ∝W, and percentage (%).
CAUTION	The Channel 2 input path circuits contain sensitive GaAs semiconductors.
	To prevent damage to these components, always adhere to standard ESD
	(ElectroStatic Discharge) prevention procedures, and ensure that the
	maximum power specification for this channel (+27 dBm) is not exceeded.
	Power Measurement Example
	This example assumes that a signal is currently applied to the Channel 2
	input connector.

1Press the Display Power key to enable power measurement.

The Pwr annunciator at the left side of the display is activated, and the Counter’s digital and analog power displays show the power measurement in dB or dBm (the default units of measurement).

The display should look like this:
