The peak volts measurement will keep operating up to 400 MHz, although results act as references only.
Tres is the resolution including effect of certain internal errors.
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.
