4. Program the Calibrator Mainframe to output the wave type and voltage listed in
Table 6-71.
5. Allow the 5790A reading to stabilize, then record the 5790A rms reading for each
wave type and voltage in Table 6-71.
6. Multiply the rms reading by the conversion factor listed to convert it to the peak-to-
peak value.
7. Multiply the peak-to-peak value by (0.5 * (50 + Rload) / Rload), where Rload = the
actual feedthrough termination resistance, to correct for the resistance error.
Compare result to the tolerance column.
