Switch Interface—Properties
Switch UseCommonRefIlPdl
Description This property returns or sets a value that determines if the
reference measurement performed on switch port 1 (for IL and
PDL) is applied to all switch ports.
Syntax object.UseCommonRefIlPdl = [Boolean]
The following table presents the possible settings for the
Boolean value.
Parameters If the property is used to indicate that the reference value of
switch port 1 must be applied to all switch ports, use a Boolean
value.
Response If the property is used to find out if the reference value of switch
port 1 is being applied to all switch ports, it will return a Boolean
value.
True: A common reference value for IL and PDL is used.
False: No common reference value for IL and PDL is used
(each port has its own reference).
Access Get/Let
Setting Description
True Allows to use the reference value of switch
port 1 as the reference value for all of the other
switch ports. Using the same reference value
for all ports speeds up the referencing process,
especially when working with large switches.
However, the result accuracy will be affected.
False (Default). Since no common reference will be
applied to switch ports, individual reference
measurements will have to be performed.
