The peak volts measurement will keep operating up to 400 MHz, although results act as references only.
The differential channel Error terms which counted by many systematic uncertainty equations result channel-to-channel disaccord and internal noise. These issues can be improved by the TI calibration in the well-controlled temperature environment.

The graph doesn’t include the effects of trigger error. To place an upper bound on the added effect of this error term, it’s necessary to determine the frequency error from the proper graph and add a trigger error term as the following equation:
External source and input amplifier noise might advance or postpone the trigger points that define the start and end of a measurement. The resulting timing uncertainty is a function of the slew rate of the signal and the amplitude of spurious noise spikes (relative to the input hysteresis band).
The (rms) trigger error relative to a single trigger point is:
