Definition of Measurement Error Sources and Terms used in Calculations
Accuracy Specifications
1. Apply the appropriate errors detailed for each measuring function.
2. Use Timebase Uncertainty in Basic Accuracy calculations only for Measurement Functions that show the ● symbol in the Timebase
3. Assumes Gaussian noise distribution and non-synchronous gate, non-gaussian noise will effect Systematic Error. Note all optional
4. Typical is achieved with an average of 100 readings with 100 samples per trigger. Worst case is trigger and sample count set to 1.
5. Improved frequency ratio, duty and phase specifications are possible by making independent measurements.
6. Minimum Pulse Width for using stated linearity is 5 ns; Pulse Widths of 2-5 ns use linearity=400 ps.
7. Residual instrument Rise/ Fall Time 10%-90% 2.0 ns (typ). Applies to fixed level triggering. Threshold can still be set based on % of
8. Input signal slew rates and settling time have effects on offset. Offset is calibrated with rise times < 100 ps.
9. Constant Duty or Phase are required during the measurement interval. Duty and Phase are calculated based on two automated
10. Duty is represented as a ratio (not as a percent).
11. Additional count errors need to be added for gated totalize error, latency or jitter. If gated, add gate accuracy term (See Totalize
12. Volts pk error apply for signal levels between full range and 1/10th range. Spec applies to sine wave only.
13. Specifications apply to signals from ±13 dBm, operable to ±19 dBm.
14. Use the R
15. Applies when Burst Width * Carrier Freq > 80.
16. Specifications based on gate and width for automated detection. If in manual mode, delay and width selected will impact accuracy
17. Specifications apply if measurement channels are in 5 V range, DC coupled, 50Ω terminated and at fixed level. The following
Single-Period: <250 MHz, 50% Duty
Phase, Dual Channel Time Interval: <160 MHz, 50% Duty
Confidence Level (k)
For 99% Confidence use k= 2.5 in accuracy calculations.
For 95% Confidence use k= 2.0 in accuracy calculations.
