Enables the mode to improve non-harmonics performance (low spurs mode).
Note: When this mode is enabled, the instrument switching speed and behavior of
the source's settled signal are affected.
Enables the optimize signal-to-noise ratio state (Optimize S/N) On or Off.
The optimize signal–to–noise softkey changes the attenuator and alc setting to provide
optimal signal–to–noise performance; it does not change the RF output power.
Caution: When the optimize signal-to-noise ratio state is enabled, some increased levels of
harmonic distortion can occur. This increased harmonic distortion could degrade ACPR and
EVM.
Note: This mode is mutually exclusive with attenuator hold (Atten Hold), and any modulation
type. A settings conflict error will be generated if attentuator hold or any modulation is
activated when optimize signal–to–noise is active (On).
For details on each key, use key help
as described on page 44.
Agilent X-Series Signal Generators User's Guide
Sets the current relative
phase of the RF output
signal as the zero
reference.
All subsequent
adjustments are relative
to this adjustment.

Setting Frequency and Power (Amplitude)
In Amplitude mode, this menu is
automatically displayed when entering
a numeric value with the front panel
keypad.
Opens the
Atten/ALC
Control
menu.
This softkey sets a user
determined maximum power
level on the instrument that is
persistent.

Modifies the attenuator and ALC settings
for optimal performance. It does not
change the RF output power.
Basic Operation
dBuVemf terminates
the value as dBuV
electromotive force.
Emf is the output
voltage with no
load. This unit is
external only.
Internal
representation as
well as increment
and decrement
values are in dBm.
Note: dBuV, mV,
and nVemf behave
similarly (i.e. Values
are external only.
Internal
representation as
well as increment
and decrement
values are in dBm.).
Available on vector
models with BBG.
Enables the instrument
to select between two
power levels with a
hardware marker or
using an external BNC.
