ON OFF
activates (ON) or deactivates (OFF) the power-sweep function, which sweeps
the output power of the tracking generator over the selected power-sweep
range. The value of the power-sweep range is displayed in the active-function
block when
range is a function of the source attenuator setting: For power sweeps, press
SRC ATN MAN AUTO until (MAN) is underlined so the spectrum analyzer source
attenuator is manually set (decoupled). For a given source attenuation setting,
the maximum specified power-sweep range is given by the following:
the source attenuation setting) to (0 dBM minus the source attenuation
setting). For example, if the source attenuation setting is 20 dB, the maximum
power sweep range is from -35 dBm (-15 dBm - 20 dB) to -20 dBm
(0 dBm - 20 dB). The starting power level is the source power setting. The
ending power level is the sum of the source power setting plus the source
power sweep setting. Source power sweep may be set as high as 20 dB, but
performance is specified only up to 15 dB.
also related to the source attenuation setting. See Table 7-13.
The output power of the tracking generator is swept according to the sweep
rate of the spectrum analyzer. The output power is always swept from the
source power setting to a higher power setting (negative source power sweep
values are not allowed). Refer to the calibration guide for your instrument for
more information regarding source power and source attenuation relationships.
Power-sweep measurements are particularly useful in making gain compression
measurements or output power versus frequency measurements.
