Basic Operation Click the MEAS key then the following menu appears. DSO1000B(V) Series HandHeld Oscilloscope User Manual 32 Options Settings Comments Source CH1 CH2 Select the measure source. Measurement Type 1 Frequency Calculate the waveform frequency by measuring the first cycle. 2 Period Calculate the time of the first cycle. 3 Mean Calculate the arithmetic mean voltage over the entire waveform. 4 Pk-Pk Calculate the absolute difference between the greatest and the smallest peaks of the entire waveform. 5 CRMS Calculate the Root Mean Square voltage over the entire waveform. 6 PRMS Calculate the actual RMS measurement of the first complete cycle in the waveform.
7 Min The most negative peak voltage measured over the entire waveform. 8 Max The most positive peak voltage measured over the entire waveform. 9 Rising Measure the time between 10% and 90% of the first rising edge of the waveform. 10 Falling Measure the time between 90% and 10% of the first falling edge of the waveform. 11 + Width Measure the time between the first rising edge and the next falling edge at the waveform 50% level. 12 - Width Measure the time between the first falling edge and the next rising edge at the waveform 50% level. 13 + Duty Measure the first cycle waveform. Positive Duty Cycle is the ratio between positive pulse width and period.
14 - Duty Measure the first cycle waveform. Negative Duty Cycle is the ratio between positive pulse width and period. 15 Base Measure the highest voltage over the entire waveform. 16 Top Measure the lowest voltage over the entire waveform. 17 Middle Measure the voltage of the 50% level from base to top. 18 Amplitude Voltage between Vtop and Vbase of a waveform. 19 Overshoot Defined as (Base - Min)/Amp x 100 %, Measured over the entire waveform. 20 Preshoot Defined as (Max - Top)/Amp x 100 %, Measured over the entire waveform. 21 PMean Calculate the arithmetic mean voltage over the first cycle in the waveform. 22 FOVShoot Defined as (Vmin-Vlow)/Vamp after the waveform falling.
23 RPREShoot Defined as (Vmin-Vlow)/Vamp before the waveform falling. 24 BWidth The duration of a burst measured over the entire waveform. 25 Delay 1-2 ↑ The time between the first rising edge of source 1 and the first rising edge of source 2. 26 Delay 1-2 ↓ The time between the first falling edge of source 1 and the first falling edge of source 2. 27 LFF The time between the first falling edge of source 1 and the last falling edge of source 2. 28 LFR The time between the first falling edge of source 1 and the last rising edge of source 2. 29 LRF The time between the first rising edge of source 1 and the last falling edge of source 2.
