Amplitude Compensation (only with Option U02)
Amplitude can be offset by up to +/-50dB to compensate for external
attenuation or gain.
Ω
Compensation can be made for inputs from a 75
Ω
Tables:
Linearly interpolated tables of up to 49 frequency/amplitude points can
be used. Up to 999 tables can be stored. Table files are created using
Automatic Measurements (only with Option U02)
Channel Power, Adjacent Channel Power Ratio, Occupied Bandwidth.
1081 data points are used for calculation.
Displays power for a user-set centre frequency and channel width.
Power Ratio:
Displays the absolute power of the main channel and the relative
power of the upper and lower adjacent channels.
Positions markers and displays bandwidth and true power centre
frequency for a user-set % power across the set sweep.
13.1.3 Sweep and Traces
Sweep
Detection for 271 points per sweep. The level, as set by the detector
type (default = positive peak), found within each sub-span is stored
Set automatically by Span, RBW/VBW and Sweep Mode.
Manual control is provided enabling sweep time to be reduced in three
steps subject to a potential reduction in level accuracy.
Normal (repeat) or Single, (Triggerable with Option U02)
(Only with Option U02), External or Limits Comparator
Several sweep modes can be selected offering a different balance
between image rejection and sweep speed.
Selectable as Positive Peak (default), Negative Peak, Alternate Peak,
Sample, Linear or Log Average, or RMS.
Traces
8.5 x 10 divisions light grey graticule. Selectable as normal, dim, or
off.
Up to 3 – Live, View and Reference (up to 4 when in Dual Trace
mode)
Dot-joined trace from current or held sweep. Selectable on or off.
Additional trace created from the live trace. Selectable on or off.
Trace recalled from a file. Selectable on or off.
Normal, Peak Hold, or Average (2 to 48 sweeps)
In Peak Hold or Average trace modes, the Normal trace can be
displayed simultaneously with the processed trace.
13.1.4 Scan Mode (only with Option U02)
High resolution capture of up to 210,000 points defined by span and
RBW. Number of points = 3 x (Span/RBW) +1.
Over-view display of whole scan with Zoom and Pan capability to
magnify view up to 1 display point per capture point.
Moveable marker with frequency readout with Pan/Zoom around
marker point. Amplitude readout at maximum magnification.
