Description
This command is used to specify the measurement algorithm during
characterization measurements for the measurement specified by the
measurement name identifier.
BINary
: The Binary algorithm uses a variable step size to find the highest
passing SJ amplitude at each SJ frequency in the template. Starting at the
maximum SJ amplitude determined by the upper limit in the template file
or the instrument limit, whichever is lower, followed by the minimum SJ
amplitude determined by the lower limit in the template file, the Binary
algorithm then sets subsequent SJ amplitudes at the logarithmic midpoint
between the highest passing and lowest failing SJ amplitudes. A test point
is determined to be a passing point if the BER measured is below the BER
threshold set by the user.
BDLinear
: The Down Linear algorithm is the same as the Binary
algorithm followed by the Down Linear algorithm. Refer to the descriptions
for Binary and Down Linear.
BULinear
: The Up Linear algorithm is the same as the Binary
algorithm followed by the Up Linear algorithm. Refer to the descriptions
for Binary and Up Linear.
DLINear
: The Down Linear search algorithm starts at the maximum jitter
value determined by the template.
If a BER measurement has errors above the measurement threshold, the
jitter amplitude is adjusted lower by the linear step size.
