When in full span, ADC dither raises the noise floor at the edges of the
120 MHz.
Changing between the Continuous and Single captures and adjusting
the Trigger settings
— Press Sweep 3.
— Then choose from the following:
296
— IF BW Sets the Digital IF bandwidth of the instrument. The
relationship between the IF bandwidth and sample rate can be
described by the following equation:
sample rate = 1.25 * IF BW.
(Default: 10 MHz, minimum: 10 Hz, maximum: 120 MHz)
— Single When pressed, Single automatically sets Continuous to OFF
and causes the application to make one acquisition.
— Continuous Toggles Continuous between ON and OFF. When
Continuous is ON, each Run/Hold press causes the application to
toggle between continuous acquisitions and Hold. When Continuous
is OFF, each Run/Hold or Single press causes the application to
make one acquisition.
— Restart When pressed, Restart causes the FieldFox to restart trace
averaging at count of 1. When in Single sweep mode, the IQA will
perform a complete set of averages before returning to the hold
state.
Description
This is a Kaiser-Bessel window whose maximum side-lobe
level is -120 dB.
This is a Gaussian window whose maximum side-lobe level is
-60 dB.
This is a Gaussian window whose maximum side-lobe level is
-70 dB.
This is a Gaussian window whose maximum side-lobe level is
-80 dB.
This window is the central lobe of the sin(x)/x (often called
sinc(x)) function.
This is a tukey (cosine-tapered) window with alpha equal to
0.25.
