:PLUGin:JTOLerance:MSETup:LOG:SSIZe[?]
Syntax
:PLUGin:JTOLerance:MSETup:LOG:SSIZe ‘identifier’, <NRf>
:PLUGin:JTOLerance:MSETup:LOG:SSIZe? ‘identifier’
Input
Parameters
‘identifier’: Specify the measurement name.
<NRf>: Set the step size.
Return Range
0.1% to 50%
Description
This command is used to set the step size for each step of the Up
Logarithmic and Down Logarithmic algorithms for the measurement
specified by the measurement name identifier.
When Down Logarithmic is enabled as the search algorithm, the
measurement starts from the maximum (which depends on the jitter
frequency). A percentage of 50%, for example, may result in a sequence of
100 UI, 50 UI, 25 UI and so on. The test for one frequency stops when the
BER limit is met or the specified minimum amplitude is reached.
When Up Logarithmic is enabled as the search algorithm, the
measurement starts from the specified minimum amplitude. A percentage
of 50%, for example, may result in a sequence of 0.1 UI, 0.15 UI, 0.23 UI
and so on. The test for one frequency stops when the BER limit is crossed
or the maximum amplitude (which depends on the jitter frequency) is
reached.
This SCPI is applicable for M8041A, M8051A, M8061A, M8062A and
M8046A.
