Explanation
Source Waveform
Select the source waveform from CH1 to CH4 or from M1 to M4.
Measurements cannot be made on a snapshot waveform or an accumulated waveform
that is not the most recent waveform.
Measurement Items
Select any of the 29 measurement items or the delay item. The abbreviations used to
display the items on the screen are indicated in parentheses.
• The DL9000 can store a total of up to 100000 data values for all traces (CH1 to CH4
and M1 to M4) in measurement areas 1 and 2.
• The DL9000 can display up to 16 waveforms on the screen.

V1(x) : Voltage at the crossing point of the specified trace and T1 (the left edge of the time
range)
V2(x) : Voltage at the crossing point of the specified trace and T2 (the right edge of the time
range)
Δ
T(x) : Time difference between T1 and T2
* The x in parentheses is the trace name. For example, it is C1 for CH1 and M1 for M1.
