Noise Figure Measurements Option (K30) R&S FSL
1300.2519.12 4.250 E-11
Result displays
The result displays consist of two panes:
• Current Value pane
In the title bar of this pane, the current measurement mode of the noise figure measurement (on the
left) and the calibration status of the noise figure measurement (on the right, if the second stage
correction is switched on) are displayed.
Below, the settings and measurement results for the currently selected measurement point in the
frequency list are displayed:
Parameter Description
RF Receive frequency at the DUT at which the current values were measured (Hz).
LO Local oscillator frequency (Hz), only displayed for frequency–converting measurements
IF Intermediate frequency (Hz), only displayed for frequency–converting measurements
ENR ENR value (dB), refers to the receive frequency (RF)
Loss In Loss at the input of the DUT (dB), refers to the receive frequency (RF)
Loss Out Loss at the output of the DUT (dB)
frequency–converting measurements: refers to the intermediate frequency (IF)
direct measurements: refers to the receive frequency (RF)
NF Noise figure measured (dB)
Noise Temp Noise temperature (K), derived from measured noise figure
Gain Gain measured (dB)

• Frequency List Result or graph (frequency list results only)
The measurement results are represented according to the measurement form (see "Measurement
forms").
• frequency list results
The measurement results for all frequencies defined in the Frequency Table are displayed in form
of a graph (see Fig. Graphical result display (example)) or a table (Frequency List Results, see
Fig.Tabular result display (example)), depending on the currently selected result display (see
Display List/Graph softkey). The measurement results are updated as the measurement is in
progress. Under Current Value, the details of the currently selected frequency in the Frequency
List Results are displayed.
