Adjusting The Frequency Settings - Keysight N9913A User Manual

IQ Analyzer (IQA) – Option 351 (CPU2 Only)
I/Q Analyzer (IQA) Mode Settings
Spectrum and RF Envelope have six markers that can be applied to any of
the 4 traces.
Waveform's six markers can be applied to RF Envelope, Real, Imaginary,
Phase, Unwrapped Phase, and Q vs. I.

Adjusting the Frequency Settings

— Press Freq/Dist.
— Then select from the following:
250
Q vs. Time – Quadrature vs. Time
Q vs. I – Quadrature vs. Imaginary
RF Envelope
Phase vs. Time
Unwrapped Phase vs. Time
Time Summary – Time Summary result includes
the capture time, spectrum analysis time and
waveform start/stop time.
— Trace 1 2 3 4 Pressing the Trace key enables you to select a different
trace number. This softkey is active when Data is set to Spectrum or
RF Envelope.
RF Envelope has four traces.
—
Real, Imaginary, Phase, Unwrapped Phase, and Q vs. I have 1 trace
—
each.
— Trace State Sets a different trace state to each of four traces. This
softkey is active when the data is set to Spectrum or RF Envelope
(Log). Pressing the Trace State softkey enables you to change the
State of the selected Trace number of the Trace Data (default: Clr/Wr
– assigned to trace 1. Traces 2, 3, and 4 are set to Blank).
— Center Sets the center frequency of the measurement trace (default:
1 GHz, minimum: 0 Hz, maximum: FieldFox model dependent).
— Freq Span (Spectrum Only) Sets the frequency span of the
measurement trace. The analyzer's digital IF bandwidth is always
equal to this value.
Changing the span causes the IF bandwidth and the sample rate to
change automatically:
Span = IF bandwidth, sample rate = 1.25 * IF bandwidth
Res BW = Span /50, if resolution bandwidth = Auto.
