• The worst BER (The greatest BER in that region).

N O T E

The above values will be returned for each mask region.

None

Number of BER violations

:MEASure:EMASk(*):FETC:CONTour?

It returns comma separated values. It starts with a series of sizes which create the

contours requested, followed by the actual coordinates, which draw the contour.

For example, if input is 672, it means 3 contours are requested, at 1e-6, 1e-8 and

1e-10 BER threshold. So, the output will have sizes of each contour, first followed

by the points of outermost contour line, then followed by the middle one at a BER

threshold of 1e-8 & then the contour line for the 1e-6.

Integer input. Switch on the bits for which contours are of interest. For example,

to see contour of the BER threshold 0.1 switch on the bit 1. To see contours for

BER 1e-6, 1e-8 & 1e-10 the input is, 0x2a0 – decimal values of which is 672.

The following values are returned: The first one is the BER value at which the

Automated Eye Parameter Measurements are calculated. The second result

denotes the lowest BER value. The third result lists the sizes of each contour

requested by the user. The fourth result gives the coordinates of each point on the

contour.
