d. The Zoom scan span limits are associated with the EMI 6 dB Resolution Bandwidth(s) (Res BW (6 dB)) that
are (displayed in the second column). The auto-coupled bandwidth choices match those CISPR Bands (displayed
in the first column), but you can also choose to manual couple (Manual) the bandwidth. When the bandwidth is
set to manual couple (Manual), the Zoom scan span limit follows the resolution bandwidth (Res BW), not the
CISPR band.
e. The Zoom scan span limits are actually the width of the FFT that is being used for the EMI 6 dB Resolution
Bandwidth (minimum == 1 FFT, so the span is limited to 1 FFT width).
— But, when using Fast SA Scan, you have a standard 3 dB resolution

Single / Continuous / Restart

This setting determines whether the FieldFox measures continuously or only
once each time the

Single
—Continuous
——ON Causes the EMI to make continuous sweeps. This is the
typical setting for making measurements. Each Run / Hold +/-
press causes the SA to toggle between continuous sweep and
Hold.
——OFF Causes the EMI to Hold. Each Run / Hold +/- or
press causes the SA to make ONE sweep, then Hold. The Hold
annotation changes to an arrow --> while the sweep occurs.
— Single Automatically sets Continuous OFF and causes the SA to
make ONE sweep, then Hold.
— Restart Resets the Average counter to 1. The Average counter also is
used with MaxHold and MinHold Trace States.
— Dwell /Point – (Active when the CISPR Measurement type == CISPR
Band Scan or CISPR Zoom Scan.) Specifies a settling time (in
seconds) between sweeps.
