13.1.2 Amplitude Measurement (Level)
Amplitude Range
Display Range:
84 dB typical
Measurement Units
dBm or dBµV (dB milliwatts or dB micro volts)
Reference Level:
Selectable between -40dBm (67 dBµV) and +20dBm (127 dBµV) with a
resolution of 1dB
Amplitude Accuracy
Ref. Level Accuracy:
Better than ± 1 dB at 2000 MHz at 10 dB below reference level
Level Flatness:
Better than ± 1 dB relative to 2000 MHz over 10 MHz to 6000 MHz
[10 MHz to 3600 MHz]
Amplitude Linearity:
Better than ± 1 dB over 60dB range down from reference level
Displayed Average Noise Level (DANL)
DANL:
Better than 120 dBm (-13 dBuV) average displayed noise floor
(ref. level = 40 dBm (+67 dBuV), RBW = 10 kHz, VBW = 1 kHz, span
1MHz) over 10 MHz to 5500 MHz [10 MHz to 3600 MHz]
Noise per Hz:
Better than -160 dBm per Hz equivalent
Distortion and Spurii
3rd Order Intermod.:
< 60dBc (typically -65dBc) for two signals at 10dB below the
reference level, 500MHz and 502MHz.
Harmonic:
< –65dBc at 10dB below reference level (100MHz)
Signal Images:
<– 55dBc, typically <60dBc (Normal sweep, 300Hz to 3MHz RBW)
Other Signal Related
Spurii
< 60dBc for signals 10dB below the reference level.
Residual Spurii:
< 70 dB below the reference level.
Amplitude Markers
Number of Markers:

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).

Limits Comparator:
Conditions of Above, Below, Inside or Outside creating actions of
beep, stop sweep, log sweep and pulse out
