Amplitude Compensation (only with Option U02)
Offset:
Amplitude can be offset by up to +/-50dB to compensate for external
attenuation or gain.
75
Compensation
Compensation can be made for inputs from a 75
source impedance.
Compensation
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
PSA-Manager software.
Automatic Measurements (only with Option U02)
Measurement Types:
Channel Power, Adjacent Channel Power Ratio, Occupied Bandwidth.
Data Points:
1081 data points are used for calculation.
Measurement Type:
Single or Continuous.
Channel Power:
Displays power for a user-set centre frequency and channel width.
Adjacent Channel
Power Ratio:
Displays the absolute power of the main channel and the relative
power of the upper and lower adjacent channels.
Occupied Bandwidth:
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
Sweep Method:
Detection for 271 points per sweep. The level, as set by the detector
type (default = positive peak), found within each sub-span is stored
(sub-span = span/270).
Sweep Time:
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.
Sweep Control:
Normal (repeat) or Single, (Triggerable with Option U02)
Sweep Trigger
(Only with Option U02), External or Limits Comparator
Sweep Modes
Several sweep modes can be selected offering a different balance
between image rejection and sweep speed.
Detector Type
Selectable as Positive Peak (default), Negative Peak, Alternate Peak,
Sample, Linear or Log Average, or RMS.
Traces
Graticule:
8.5 x 10 divisions light grey graticule. Selectable as normal, dim, or
off.
Displayed Points:
271 points per sweep.
Number of Traces:
Up to 3 – Live, View and Reference (up to 4 when in Dual Trace
mode)
Live Trace:
Dot-joined trace from current or held sweep. Selectable on or off.
View Trace
Additional trace created from the live trace. Selectable on or off.
Reference Trace:
Trace recalled from a file. Selectable on or off.
Trace Modes:
Normal, Peak Hold, or Average (2 to 48 sweeps)
Dual Trace Option:
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)
Scan Method:
High resolution capture of up to 210,000 points defined by span and
RBW. Number of points = 3 x (Span/RBW) +1.
Scan Display:
Over-view display of whole scan with Zoom and Pan capability to
magnify view up to 1 display point per capture point.
Marker:
Moveable marker with frequency readout with Pan/Zoom around
marker point. Amplitude readout at maximum magnification.
