:MEASure:EMASk(*):MARKer?

Returns the threshold delay and the BER at the left and right intersections of the

marker lines.

x coordinate of left marker intersection, y coordinate of left marker intersection, x

coordinate of right marker intersection, y coordinate of right marker intersection.

Example:

meas:emas2:marker? 90,50,260,220

First four values are used for resetting the maker. The following six values are: Left

threshold value, Left time interval value, Left BER, Right threshold value, Right time

interval value, and Right BER.

Example:

47,243,89,265,-3.901291285419E-1,-4.157517291605E-1,4.999999999537E-1,3.021

:MEASure:EMASk(*):MASK:LOAD?

Loads the Mask File from the mask file folder provided with the software.

You need to run the measurement before loading a mask file. The installed mask

files are all valid.

Example:

meas:emas:cre?

meas:gen2:go

meas:emas2:mask:load? “c:01xGbEthernet.msk”

Returns the following values: MARGIN | NOMARGIN, Mask Alignment, Signal time

period is specified in the mask file , and waveform time period is 1/ED Clk Rate.

In the input file, if min_margin and max_margin are defined for all regions, then

the output is MARGIN; and using the margin SCPIs the mask test can resize the
