  • SpecificationsFrequency Readout Accuracy ExampleFrequency: 1 GHzSpan: 400 kHzRBW: 3 kHzSweep points: 1000Calculation: (1x109Hz) x (±1.55x10–7/Year ref. Error)= 155Hz400kHz Span x 0.1%= 400Hz3kHz RBW x 5%= 150Hz2Hz + 0.5 x 400kHz/(1000-1) = 202HzTotal uncertainty = ±907Hz*Utilizing internal frequency counter improves accuracy to ±155HzBack to Basics Training23** The Maximum # of sweep points for the X-Series is 40,001 which helps to achieve the best frequency readout accuracy
