User Manual width and period. Measure the first cycle waveform. Negative Duty Cycle is the ratio between positive pulse 14 - Duty width and period. 15 Vbase Measure the highest voltage over the entire waveform. 16 Vtop Measure the lowest voltage over the entire waveform. 17 Vmid Measure the voltage of the 50% level from base to top. 18 Vamp 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 PeriodAvg 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. The time between the first rising edge of source 1 and the first rising edge of source 2 of 50 25 FRR voltage level. The time between the first falling edge of source 1 and the first falling edge of source 2 of 50 26 FFF voltage level. 27 FRF The time between the first rising edge of source 1 and the first falling edge of source 2. 28 FFR The time between the first falling edge of source 1 and the first rising edge of source 2.
29 LRR The time between the first rising edge of source 1 and the last rising edge of source 2. 30 LRF The time between the first rising edge of source 1 and the last falling edge of source 2. 31 LFR The time between the first falling edge of source 1 and the last rising edge of source 2. 32 LFF The time between the first falling edge of source 1 and the last falling edge of source 2. Delay settings When the 8 delay measurements of FRR, FFF, FRF, FFR, LRR, LRF, LFR, and LFF are selected, the source that is selected in the main menu of measure is the source 1 of delay measurement.
In the second page of measurement main menu, select Settings softkey to enter delay menu, users can set the opened channel to the source 2 of delay measurement. Gate measurement In the second page of measurement main menu, select Gate softkey to enter gate menu. Only when the type of measurement is opened, the gate measurement can be opened. After opening the gate measurement, the measurement results only measure the waveform between the cursor A and the cursor B. 2.11. DVM DVM supports 3-bit voltage and 6-bit frequency measurement of any analog channel waveform. The measurement is always performed when the oscilloscope is running or stopped.
Press [ MEASURE ] on the front panel to enter the measurement interface, and press F3 to select the DVM to enter DVM setting interface. Press CH1 Enable, CH2 Enable to enable any channel or all channels of DVM. 46 / 67
