a. The warranted performance is only the sum of all errors under autocoupled conditions. Under non-autocoupled
conditions, the frequency readout accuracy will nominally meet the specification equation, except for conditions
in which the RBW term dominates, as explained in examples below. The nominal RBW contribution to frequency
readout accuracy is 2% of RBW for RBWs from 1 Hz to 390 kHz, 4% of RBW from 430 kHz through 3 MHz (the
widest autocoupled RBW), and 30% of RBW for the (manually selected) 4, 5, 6 and 8 MHz RBWs.
First example: a 120 MHz span, with autocoupled RBW. The autocoupled ratio of span to RBW is 106:1, so the
RBW selected is 1.1 MHz. The 5% × RBW term contributes only 55 kHz to the total frequency readout accuracy,
compared to 300 kHz for the 0.25% × span term, for a total of 355 kHz. In this example, if an instrument had an
unusually high RBW centering error of 7% of RBW (77 kHz) and a span error of 0.20% of span (240 kHz), the
total actual error (317 kHz) would still meet the computed specification (355 kHz).
Second example: a 20 MHz span, with a 4 MHz RBW. The specification equation does not apply because the
Span: RBW ratio is not autocoupled. If the equation did apply, it would allow 50 kHz of error (0.25%) due to the
span and 200 kHz error (5%) due to the RBW. For this non-autocoupled RBW, the RBW error is nominally 30%,
or 1200 kHz.
b. Horizontal resolution is due to the marker reading out one of the sweep points. The points are spaced by
span/(Npts –1), where Npts is the number of sweep points. For example, with the factory preset value of 1001
sweep points, the horizontal resolution is span/1000. However, there is an exception: When both the detector
mode is “normal” and the span > 0.25 × (Npts –1) × RBW, peaks can occur only in even-numbered points, so
the effective horizontal resolution becomes doubled, or span/500 for the factory preset case. When the RBW is
autocoupled and there are 1001 sweep points, that exception occurs only for spans > 750 MHz.
c. Specifications apply to traces in most cases, but there are exceptions. Specifications always apply to the peak
detector. Specifications apply when only one detector is in use and all active traces are set to Clear Write. Specifications
also apply when only one detector is in use in all active traces and the "Restart" key has been pressed
since any change from the use of multiple detectors to a single detector. In other cases, such as when multiple
simultaneous detectors are in use, additional errors of 0.5, 1.0 or 1.5 sweep points will occur in some detectors,
depending on the combination of detectors in use.
d. In most cases, the frequency readout accuracy of the analyzer can be exceptionally good. As an example, Keysight
has characterized the accuracy of a span commonly used for Electro-Magnetic Compatibility (EMC) testing
using a source frequency locked to the analyzer. Ideally, this sweep would include EMC bands C and D and thus
sweep from 30 to 1000 MHz. Ideally, the analysis bandwidth would be 120 kHz at −6 dB, and the spacing of the
points would be half of this (60 kHz). With a start frequency of 30 MHz and a stop frequency of 1000.2 MHz and
a total of 16168 points, the spacing of points is ideal. The detector used was the Peak detector. The accuracy of
frequency readout of all the points tested in this span was with ±0.0032% of the span. A perfect analyzer with
this many points would have an accuracy of ±0.0031% of span. Thus, even with this large number of display
points, the errors in excess of the bucket quantization limitation were negligible.
