4 - 70 COMMAND REFERENCE
:TMINimum
No parameters. Measures the time of the first occurrence of the
MINimum voltage of the input signal. The unit of TMINimum is
seconds.
:RISE:OVERshoot
No parameters. Measures the overshoot of the first rising edge
of a waveform, expressed as a percentage of the waveform
AMPLitude. The rise overshoot is the difference between the
HIGH value and the MAXimum positive peak value to which the
signal initially rises, as shown in figure 3.2. The overshoot value
in volts is calculated as follows:
overshoot_value = overshoot_percentage
*
AMPLitude / 100
:RISE:PREShoot
No parameters. Measures the preshoot of the first rising edge
of a waveform, expressed as a percentage of the waveform
AMPLitude. The preshoot is the difference between the LOW
value and the MINimum negative peak value to which the signal
initially false, as shown in figure 3.2. The preshoot value in volts
is calculated as follows:
preshoot_value = preshoot_percentage
*
AMPLitude / 100
:RISE:TIME
[<reference_low> [,<reference_high> [,<expected_time>
[,<time_resolution>]]]
Measures the rise time of the first rising edge of a waveform.
This is the time interval during which the instantaneous signal
value increases from the REFerence LOW to the REFerence
HIGH value, as shown in figure 3.2. The rise time is expressed
in seconds. RTIMe is an alias of RISE:TIME.
<measure_parameters>
<reference_low> = <NRf> | DEFault
Range: 0 ... 100. Default value: 10
Specifies the REFerence LOW level as a percentage
of the HIGH value. See figure 3.2. The unit of
<reference_low> is volt.
<reference_high> = <NRf> | DEFault
Range: 0 ... 100. Default value: 90
Specifies the REFerence HIGH level as a percentage
of the HIGH value. See figure 3.2. The unit of
<reference_high> is volt.
