Descriptions of the Measurement Functions— <function> (Cont.)

:MEASure[:SCALar][:VOLTage]:FALL:TIME? [<lower_reference>[,upper_reference>]][,(@1)]

Measures Fall Time.

The measurement arming is coupled to “auto.”

The Counter uses the <lower_reference> and <upper_reference> to select the lower and upper points on the falling edge of an input signal applied to channel 1. These reference points can be specified as either a percentage or an absolute voltage. The default units are percent.

The <lower_reference> and <upper_reference> parameters are used to configure the Channel 1 and Channel 2 trigger settings, respectively. When a reference is specified as a percentage (or defaulted),

auto-trigger is enabled and auto-trigger level is set to the specified (or defaulted) value. When a reference is specified in volts,

auto-trigger is disabled and the absolute trigger level is set to the specified value.

<lower_reference>
percent range:	0 to 100 [PCT]
percent resolution:	10%
voltage range:	For volts if X1 Attenuation: -5.125V to +5.125V
	For volts if X10 Attenuation: -51.25V to +51.25V
voltage resolution:	For volts if X1 Attenuation: .005V
	For volts if X10 Attenuation: .05V
default:	10 PCT
<upper_reference>
