TDS3000, TDS3000B, and TDS3000C Series Programmer Manual
NEGAtive sets the oscilloscope to trigger only on negative-polarity slew rate
signals.
TRIGGER:A:PULSE:SLEWRate:POLARITY NEGATIVE
specifies that the oscilloscope only trigger on negative-polarity pulses or slew
rates.
TRIGger:A:PULse:SLEWRate:SLEWRate
Sets or returns the slew rate value in volts per second.
Trigger
TRIGger:A:PULse:SLEWRate:SLEWRate <NR3>
TRIGger:A:PULse:SLEWRate:SLEWRate?
<NR3> is a floating point value with exponent that sets the slew rate value as
volts per second
TRIGger:A:PULse:SLEWRate:SLEWRate?
might return TRIGGER:A:PULSE:SLEWRATE:SLEWRATE 1.547E-3, indicating a
slew rate of 1.54 mV/s.
TRIGger:A:PULse:SLEWRate:THReshold:BOTh
Sets the slew rate source signal threshold values.
Trigger
TRIGger:A:PULse:SLEWRate:THReshold:BOTh { TTL | ECL }
TTL sets the upper threshold to 2.0 V and the lower threshold to 0.8 V.
ECL sets the upper threshold to --1.1 V and the lower threshold to --1.5 V.
TRIGGER:A:PULSE:SLEWRATE:THRESHOLD:BOTH TTL
sets the upper slew rate threshold value to 1.8 V and the lower threshold value to
0.8 V.
