MASK:MASKPRE:PATTERNBITS
(Requires TDS3TMT)
Sets or returns the number of bits used for serial trigger for the current standard.
For example, DS1 requires six bits; four leading zeros, a one, and a trailing zero.
The query form of this command returns the serial bit value of the displayed
mask. The set form of this command only affects the User mask, regardless of
the current (displayed) mask.
Mask
MASK:MASKPRE:PATTERNBITS <NR1>
MASK:MASKPRE:PATTERNBITS?
<NR1> is an integer that sets the number of bits.
MASK:MASKPRE:PATTERNBITS 6
sets the User mask number of serial pattern bits to 6.
MASK:MASKPRE:PRESAMPBITS
MASK:MASKPRE:SERIALTRIG
MASK:MASKPRE:PRESAMPBITS
(Requires TDS3TMT)
Sets or returns the number of bits before the (isolated one) pulse leading edge in
serial trigger pass/fail testing. For example, DS1 has four leading zeros. The
query form of this command returns the presample bit value of the displayed
mask. The set form of this command only affects the User mask, regardless of
the current (displayed) mask.
Mask
MASK:MASKPRE:PRESAMPBITS <NR1>
MASK:MASKPRE:PRESAMPBITS?
<NR1> is an integer number that sets the number of bits before the trigger pulse.
