Label Information
Signal Frequency Current carrier frequency of the applied signal.
Signal Level Currently level measured on the carrier frequency.
Att Current RF attenuation.
RBW Current Resolution bandwidth (RBW). The RBW is a function of the
start offset frequency of each half decade included in the measure-
ment.
XCORR Factor Current cross-correlation factor. The cross-correlation factor defines
the number of cross-correlations are done in each half decade inclu-
ded in the measurement.
Meas Time (estima-
ted)
Current estimated measurement time.
The measurement time depends, among other things, on the offset fre-
quency, the resolution bandwidth or the number of averages / cross-
correlations that you have defined.
Source Frequency Current frequency of the signal source output.
Displayed if the optional signal source is installed.
Source Level Current level of the signal source output.
Displayed if the optional signal source is installed.
SGL Current number of measurements performed in a single sweep. Only
displayed if you are in single sweep measurement mode.
Count The current signal count for measurement tasks that involve a specific
number of subsequent sweeps.
Meas Currently selected measurement (Phase Noise, Additive Phase Noise
etc.).
Input ExtMix Currently selected waveguide band of an external mixer. Only dis-
played if an external mixer is selected as an input source.
Gain Difference between DUT signal level and signal source level.
Displayed in Additive Noise measurements.
Icons for individual settings
A bullet next to the setting indicates that user-defined settings are used, not auto-
matic settings. A green bullet indicates this setting is valid and the measurement
is correct. A red bullet indicates an invalid setting that does not provide useful
results.
