Duty Cycle
Measurement is specified over the full signal range of Channel 1. However, both the positive and negative pulse widths must be greater
than 4 ns.
Results Range:
0 to 1 (e.g. 50% duty cycle would be displayed as .5)
RMS Resolution:

Measurement is specified over the full signal range of Channel 1.
Results Range:

Resolution: ± 1 count
Peak Volts
Measurement is specified on Channels 1 and 2 for DC signals; or for AC signals of frequencies between 100 Hz and 30 MHz with peak-to-
peak amplitude greater than 100 mV. (The measurement will continue to operate up to 225 MHz, though results are for indication only.)
Results Range:
–5.1 V to +5.1 V
Resolution: 10 mV
Systematic Uncertainty for AC signals: 25 mV + 10% of V
for DC signals: 25 mV + 2% of V
Use of the input attenuator multiplies all voltage specifications (input range, results range, resolution and systematic uncertainty) by a
nominal factor of 10. For example with AC signals, the Systematic Uncertainty becomes: 250 mV + 10% of V.
