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.
