You can either enter the values for the measurement bandwidth and number of
cross-correlation operations directly. Or you can let the application calculate ideal
values for each half decade.
1. Enter the "Overview" dialog box, and from there, enter the "Noise Config" dia-
log box.
2. Select automatic or manual configuration mode with the "Half Decade Config"
feature.
3. In case of an
automatic configuration
, define an "RBW" factor and an
"XCORR Factor".
From these values, the application calculates the best and least time-consum-
ing absolute resolution bandwidth and cross-correlation operations for each
half decade.
4. In case of a
manual configuration
, define the resolution bandwidth and num-
ber of cross-correlations for each half decade directly in the half decade con-
figuration table as absolute values.
The relative "RBW" factor and "XCORR Factor" are ignored.

Pulsed Measurement Configuration
How to configure a gate for measurements on pulses
Noise measurements on pulses are available with the optional pulsed phase
noise measurements firmware application.
By default, the application automatically detects the pulse characteristics and
defines the gate characteristics based on the pulse. If required, you can also
define these parameters manually.
1. Enter the pulsed phase noise measurement.
2. Select the [MEAS CONFIG] key and enter the "Pulse" dialog box with the
"Pulse Config" softkey.
3. In the "Pulse" dialog box, select "Manual" pulse detection.
The input fields for the "Pulse Repetition Interval" and those for the "Gate
Characteristics" become available. You can change them if required.
4. Configure the "Pulse Rep Interval" as required.
