Description Specifications Supplemental Information
Channel Power Input signal must not be bursted
(5.6 MHz Integration BW)
Minimum power at RF Input –50 dBm (nominal)
Absolute Power Accuracy
a
(20 to 30°C)
a. Absolute power accuracy includes all error sources for in-band signals except mismatch errors and
repeatability due to incomplete averaging. It applies when the mixer level is high enough that measure-
ment floor contribution is negligible.
±0.94 dB ±0.27 dB (95th percentile)
Measurement floor –80.2 dBm (typical)

Channel Power with Shoulder
Attenuation View Input signal must not be bursted
(5.60 MHz Integration BW,
ML = –16 dBm, Shoulder
Offset
a
= 3.40 MHz)
a. Shoulder offset is the midpoint of the Shoulder Offset Start and Shoulder Offset Stop settings. The
specification applies with the default difference between these two of 200 kHz.
Dynamic Range, relative
b
b. The dynamic range specification is the ratio of the channel power to the power in the offset and region
specified. The dynamic range depends on the measurement settings, such as peak power or integrated
power. This specification is derived from other analyzer performance limitations such as third-order
intermodulation, DANL and phase noise. Dynamic range specifications are based on default measure-
ment settings, with detector set to average, and depend on the mixer level. Mixer level is defined to be
the input power minus the input attenuation.

Power Statistics CCDF
Minimum power at RF Input –50 dBm (nominal)
Histogram Resolution 0.01 dB
a
a. The Complementary Cumulative Distribution Function (CCDF) is a reformatting of a histogram of the
power envelope. The width of the amplitude bins used by the histogram is the histogram resolution.
The resolution of the CCDF will be the same as the width of those bins.
