frequency)]
Magnitude Specifications
Magnitude Accuracy (Flattop window) 0.26 dB (3%) Near dc, −3
dB at maximum bandwidth
Signal-to-noise Ratio 55 to 65 dB (typical).
Controls
Span Sets the maximum frequency
Resolution Sets the spacing between points in the frequency domain
Magnify Controls For zooming in on a portion of the frequency
record up to an expansion factor of 200. The magnify controls are:
magnify on/off, magnify span, and center frequency.
Vertical Scaling The vertical scale is adjustable in dBm, a
logarithmic scale. You can adjust sensitivity and offset.
Window There are three windows for reducing leakage and
enhancing certain characteristics in the frequency domain.
there are an integral number of cycles in the time record.
