Agilent Technologies 8922M, S GSM manual Phase, Frequency Error, Measurement Method

	Making Measurements
	Measurements
Phase and	Phase error and frequency error are measures of the modulation and noise
Frequency Error	performance of the radio’s transmitter path.
Measurement
	Method
	Select the PHASE FRQ field on the cell control screen to access the phase and
	frequency measurements.
NOTE	The test is run automatically when the screen is selected.
	The measurement fields in this screen are RMS Phase Error, Peak Phase Error and
	Frequency Error (1), see Figure 2-7 on page 2-15.
	The Agilent 8922M/S input sensitivity (2) can be varied, if necessary, to ensure that
	the input signal level matches the Agilent 8922M/S RF Analyzer. Valid
	measurements are only made when the signal is within 3 dB of the RF Analyzer
	setting.
	The Agilent 8922M has the option of using multi-burst measurements (4). This
	gives the ability to make several phase and frequency measurements using more
	than one burst. For more information refer to Chapter 4, Screens, Phase and
	Frequency Error screen.
