Fluke PM-3394B, PM-3380B, PM-3390B, PM-3370B, PM-3384B user manual Falltime, High

4 - 68	COMMAND REFERENCE
:FALL:OVERshoot	No parameters. Measures the overshoot of the first falling edge
	of a waveform, expressed as a percentage of the waveform
	AMPLitude. The fall overshoot is the difference between the
	LOW value and the MINimum negative peak value to which the
	signal initially falls, as shown in figure 3.2. The overshoot value
	in volts is calculated as follows:
	overshoot_value = overshoot_percentage * AMPLitude / 100
:FALL:PREShoot	No parameters. Measures the preshoot of the first falling edge
	of a waveform, expressed as a percentage of the waveform
	AMPLitude. The fall preshoot 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 preshoot value
	in volts is calculated as follows:
	preshoot_value = preshoot_percentage * AMPLitude / 100
:FALL:TIME	[<reference_low> [,<reference_high> [,<expected_time>
	[,<time_resolution>]]]
	Measures the fall time of the first falling edge of a waveform.
	This is the time interval during which the instantaneous signal
	value decreases from the REFerence HIGH to the REFerence
	LOW value, as shown in figure 3.2. The fall time is expressed
	in seconds. FTIMe is an alias of FALL:TIME.
:FREQuency	[<expected_frequency> [,<frequency_resolution>]]
	Measures the frequency of the input signal. The frequency is
	the inverse of the PERiod as shown in figure 3.2. The frequency
	is expressed in hertz.
:HIGH	No parameters. Measures the HIGH value of the waveform, as
	shown in figure 3.2. The HIGH value is the more positive of the
	BASE and TOP signal as defined by the standards IEC 469 and
	IEEE 194. The HIGH value is expressed in volts.
:LOW	No parameters. Measures the LOW value of the waveform, as
	shown in figure 3.2. The LOW value is the less positive of the
	BASE and TOP signal as defined by the standards IEC 469 and
	IEEE 194. The LOW value is expressed in volts.
:MAXimum	No parameters. Measures the MAXimum instantaneous
	voltage value of the waveform. The unit of MAXimum is volt.
