Figure 5-22 Power Search and ALC Off Softkeys
Only available when
I/Q is on.
These
softkeys are
only active
when an ARB
waveforms is
playing in
memory.
Available only when
ALC = Off

Sets the allowed
settling error.
Auto: The calibration routine executes whenever
output frequency or amplitude changes.
Available only when
Power Search Reference =
Manual
Available only when
Power Search = Span
User: Enables the
user to set the
signal generator
frequency settings.
Full: The signal
generator selects
its full frequency
range for the power
search.
N5173B/83B only
Only available when
I/Q is on.
For details on each key, use key help as described on see
Agilent X-Series Signal Generators User's Guide
Span: Pressing Do Power Search executes the
power search calibration routine once over a
selected frequency range.
The corrections are stored and used whenever you
tune the signal generator to within the calibrated
frequency range.
Manual: User must explicitly execute a power
search to calibrate the open loop ALC level.
RMS: Value is a DC
bias equivalent to the
value derived from the
file header or the
calculated value from
the current I/Q data.
Fixed: Uses a fixed 0.5
Vrms value (Same
value is used with Ext
I/Q data).
Manual: Allows user to
specify the DC bias
voltage value
(0–1.414 Vrms).
Modulated: Uses the
AC bias from the actual
modulating signal.
