1 Add the imp edance measuremen t accuracy [%] to the voltage level monitor
accuracy when the DUT's imp edance is < 100 .
2 Add the imp edance measuremen t accuracy [%] to the current level monitor
accuracy when the DUT's imp edance is 100 .
Accuracies apply when test cable length is 0 m or 1 m. additional
error when test cable length is 2 m or 4 m is given as:
f

[%]
Where, f
m
is test frequency [MHz],
L is test cable length [m].
Example DUT's imp edance : 50
T est signal lev el : 0.1 V
rms
Measuremen t accuracy : 0.1 %
Then, V oltage lev el monitor accuracy is
6(3.1 % of 0.5 mV
