　　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

　　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.
