Phase of Input 1 relative to Input 2
Measures the phase difference between the waveforms
applied to Inputs 1 and 2. The value displayed is the phase
lead of Input 1 in degrees.
Note: A continuous signal is required during a phase
measurement.
Phase of Input 2 relative to Input 1
Measures the phase difference between the waveforms
applied to Inputs 2 and 1. The value displayed is the phase
lead of Input 2 in degrees.
Note: A continuous signal is required during a phase
measurement.
Risetime Input 1
Measures the 10% to 90% risetime of the waveform at Input
1.
Falltime Input 1
Measures the 90% to 10% falltime of the waveform at Input
1.
Positive pulse width Input 1
Measures the width of positive going pulses at Input 1 (i.e. ↑
edge to ↓ edge).
Negative pulse width Input 1
Measures the width of negative going pulses at Input 1 (i.e.
↓ edge to ↑ edge).
Volts middle Input 1
Measures the middle (mean) voltage of the waveform at
Input 1.
Volts middle Input 2
Measures the middle (mean) voltage of the waveform at
Input 2.
Volts maximum Input 1
Measures the maximum (peak) voltage of the waveform at
Input 1.
Volts maximum Input 2
Measures the maximum (plus peak) voltage of the
waveform at Input 2.
Volts minimum Input 1
