MASK:MASKPRE:TRIGTOSAMP
Arguments
<NR3> is a floating point number that sets the nominal bit width in seconds. This
number is the time of one bit of data where bit width = 1 / ( data rate of the signal ).
Examples
MASK:MASKPRE:WIDTH 648E-9 sets the current mask nominal bit width to
648 nanoseconds (1.544 Mbits/second).
MASK:MASKPRE:WIDTH? might return :MASK:MASKPRE:WIDTH 500.0000E–9,
indicating that the bit width value of the displayed mask is set to 500 nanoseconds.
MASK:POLarity
This command sets or returns the input waveform polarity for the pass/fail test.
It con
trols whether to test positive pulse, negative pulse, or both during pass/fail
testing. This command only applies when MASK:TESt:STATE is on.

Syntax
MASK:POLarity {BOTh|NEGAtive|POSITIVe}
MASK:POLarity?
Related Commands
MASK:TESt:STATE
Arguments
BOTh enables testing for both positive and negative pulses. The instrument tests
positive pulses on the mask:source waveform until ½ of the waveform has been
tested. Then the instrument inverts the mask and performs the remaining tests.
NEGAtive enables testing on negative pulses.
