IQ Analyzer (IQA) – Option 351 (CPU2 Only)
I/Q Analyzer (IQA) Mode Settings
For Waveform Measurement:
— 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.
— 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).
Adjusting the Frequency Settings
—Press Freq/Dist.
— Then select from the following:
— Center
Sets the center frequency of the measurement trace (default:
1 GHz, minimum: 0 Hz, maximum: FieldFox model dependent).

the capture time, spectrum analysis time and
waveform start/stop time.

Time Summary – Time Summary result includes
the capture time, spectrum analysis time and
waveform start/stop time.
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.
— RF Envelope has four traces.
— Real, Imaginary, Phase, Unwrapped Phase, and Q vs. I have 1 trace
each.
