Noise Floor
Noise Floor:
Better than -95 dBm average displayed noise floor for F > 3MHz
(reference level = –20 dBm, RBW = 15 kHz, video filter On)
Distortion and Spurii
3rd Order Intermod.:
< –60dBc for two signals(500MHz and 502MHz) at 10dB below
reference level
Harmonic:
< –60dBc at 10dB below reference level (100MHz)
1st & 2nd Image:
<– 55dBc, typically <– 60dBc
Residual Spurii:
<3dB above noise floor
Amplitude Markers
Number of Markers:
One, Two, or None
Marker Resolution:
0.1 dB
Amplitude Readout:
Display of absolute and difference amplitudes for both markers in
graticule units (dBm or dBuV) or linear units (mV or uW).
Amplitude Limits (only with Option U01)
Limit Types: Limit Lines from numeric values, or Limit Patterns from Files. Pattern
files are created using PSA-Manager software.
Number of Limits:
One or two limits on screen. Up to 999 patterns can be stored
Limits Comparator:
Conditions of Above, Below, Inside or Outside creating actions of
beep, stop sweep, log sweep and pulse out
Amplitude Compensation (only with Option U01)
Offset:
Amplitude can be offset by up to +/-50dB to compensate for external
attenuation or gain.
75
Ω
Compensation
Compensation can be made for inputs from a 75
Ω
source impedance.
Compensation
Tables:
Linearly interpolated tables of up to 49 frequency/amplitude. Up to 999
can be stored. Table files are created with PSA-Manager software.
12.1.3 Sweep and Traces
Sweep
Sweep Method:
Peak detection for 270 points per sweep. The amplitude of the peak
level found within each sub-span is stored (sub-span = span/270).
Sweep Time: Set automatically by Span and RBW.
Typically 150ms + 2.3ms/MHz of span for RBW = 1MHz
Typically 150ms + 7ms/MHz of span for RBW = 280kHz
Typically 180ms + 77ms/MHz of span for RBW = 15kHz
Sweep Modes:
Normal (repeat) or Single
Sweep Trigger
(Only with Option U01), External or Limits Comparator
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.
