Meas Setup

of measurements (especially remote measurements where the center frequency is changing
rapidly), is reduced.

The actual frequency offset beyond which noise is optimized is shown with in square brackets, as
this can vary depending on the hardware set in use.  For example, in some analyzers this
annotation appears as [offset >30 kHz]

Key Path

Meas Setup, PhNoise Opt

Example

FREQ:SYNT 2

Couplings

The frequency below which the phase noise is optimized is model dependent:

PXA with option EP1: [offset >160 kHz]

Models with option EP2: [offset >100 kHz]

CXA with option EP4: [offset >130 kHz]

CXA without option EP4: n/a

All other models: [offset >30 kHz]

Fast Tuning

In this mode, the LO behavior compromises phase noise at many offsets from the carrier in order
to allow rapid measurement throughput when changing the center frequency or span.   The term
“fast tuning” refers to the time it takes to move the local oscillator to the start frequency and begin
a sweep; this setting does not impact the actual sweep time in any way.

In this mode in PXA, the LO behavior compromises phase noise at offsets below 4 MHz in order to
improve measurement throughput.  The throughput is especially affected when moving the LO
more than 2.5 MHz and up to 10 MHz from the stop frequency to the next start frequency.

(In models whose hardware does not provide for a fast tuning option, the settings for Best Close-
in Φ Noise are used if Fast Tuning is selected.  This gives the fastest possible tuning for that
hardware set.)
