  • Page 28 2.1 System Configuration and Block Diagram Signal Flow The signal applied to each signal input terminal is first passed to the vertical control circuit consisting of an attenuator (ATT) and pre-amplifier. At the attenuator and pre- amplifier, the voltage and amplitude of each input signal is adjusted according to the settings such as the input coupling, probe attenuation ratio, V/div, and offset voltage.

  • Page 29: Vertical And Horizontal Axis

    Vertical and Horizontal Axis Vertical Sensitivity (V/div) <For the setup procedure, see section 5.2> The vertical sensitivity setting is used to adjust the displayed amplitude of the waveform for easy viewing. The vertical sensitivity is set by assigning a voltage to one grid square (one division) on the screen.
  • Page 30 2.2 Vertical and Horizontal Axes Input Coupling <For the setup procedure, see section 5.4> If you wish to observe just the amplitude of an AC signal, it is best to remove the DC component from the input signal. On the other hand, there are times when you wish to check the ground level or observe the entire input signal (both the DC and AC components).
  • Page 31 2.2 Vertical and Horizontal Axes Probe Attenuation/Current-to-Voltage Conversion Ratio <For the setup procedure, see section 5.5> Normally a probe is used in connecting the circuit being measured to the measurement input terminal. Using a probe has the following advantages. • Avoids disturbing the voltage and current of the circuit being measured. •...
  • Page 32 2.2 Vertical and Horizontal Axes Horizontal Axis (Time Axis) Selecting the Time Base <For the setup procedure, see section 5.10> By default, the sampling timing of waveform data is controlled by the internal clock signal generated from the time base circuit within the instrument (see the block diagram in section 2.1).
  • Page 33 2.2 Vertical and Horizontal Axes Relationship between the Time Axis Setting and Sampling Mode Depending on the time axis setting, you can switch the mode used to sample the input signal (sampling mode). The time axis settings that allow the sampling mode to be changed vary depending on the acquisition mode and other settings.

  • Page 34: Triggers

    Triggers Trigger Source, Trigger Slope, and Trigger Level Trigger Source Trigger source refers to the signal against which trigger conditions are checked. Trigger Slope Trigger slope refers to the movement of the signal from a low level to a high level (rising edge) or from a high level to a low level (falling edge).
  • Page 35 2.3 Triggers Condition A: CH1 = L, CH2 = L, Enter, Condition B: CH1 = H, CH2 = H, Enter, N = 3 L: low level, H: high level Trigger B (1) B (2) B (3) Condition A true • A Delay B Trigger <For the setup procedure, see section 6.9> The trigger activates the first time condition B becomes true after condition A has become true and the preset time has elapsed.
  • Page 36 2.3 Triggers • Width Trigger <For the setup procedure, see section 6.11> A trigger is activated by determining whether the time width over which the specified condition is met or not met is shorter or longer than the determination time width set in advance.
  • Page 37 2.3 Triggers • TV Trigger <For the setup procedure, see section 6.14> This trigger is used when observing video signals. The following broadcasting types are supported: NTSC, PAL, SECAM, 1080/60i, 1080/50i, 720/60p, 480/60p, 1080/ 25p, 1080/24p, 1080/24sF, and 1080/60p. Trigger Mode <For the setup procedure, see section 6.1> Sets the conditions for updating the displayed waveforms.
  • Page 38 2.3 Triggers Trigger Position <For the setup procedure, see section 6.2> When you start waveform acquisition, a trigger is activated according to a specified trigger condition, and the waveform acquired to the acquisition memory is displayed. If the trigger delay described below is set to 0 s, the point at which the trigger is activated (trigger point) and the trigger position match.
  • Page 39 2.3 Triggers Trigger Hysteresis <For the setup procedure, see sections 6.5, 6.8 to 6.12> If there is insufficient trigger level width and noise is present in the trigger source, the trigger point fluctuates each time a trigger is activated. This causes the displayed waveforms to be unstable.

  • Page 40: Waveform Acquisition And Display Conditions

    Waveform Acquisition and Display Conditions Record Length <For the setup procedure, see section 7.2> The term record length refers to the number of data points acquired per channel in the acquisition memory. The record lengths that can be specified (specified record length) are 1 kW (1000 points), 10 kW, 50 kW, 100 kW, 250 kW, 500 kW, 1 MW, 2 MW, 4 MW, and 8 MW.
  • Page 41 2.4 Waveform Acquisition and Display Conditions Averaging Mode Averaging is a process in which waveforms are acquired repeatedly to obtain the average of waveform data at the same time point (the same time in relation to the trigger point). The instrument takes the exponential or simple average of the waveform data and writes the results to the acquisition memory.
  • Page 42 2.4 Waveform Acquisition and Display Conditions Sequential Store <For the setup procedure, see section 7.6> This function stores waveform data in the acquisition memory the specified number of times and displays the data when in realtime sampling mode. The operation stops when acquisition is finished.
  • Page 43 2.4 Waveform Acquisition and Display Conditions Display Format <For the setup procedure, see section 8.1> Splitting the Screen The screen can be split evenly so that input waveforms and computed waveforms can be easily viewed. The screen can be divided into the following: Single (no division), Dual (two divisions), Triad (three divisions), Quad (four divisions), and Hexa (six divisions)* * Quad (four divisions) and Hexa (six divisions) are not available on the DL1720E.
  • Page 44 2.4 Waveform Acquisition and Display Conditions Accumulated Display <For the setup procedure, see section 8.3> The display time of old waveforms can be set longer than the waveform update period, so that newer waveforms appear overlapped (accumulated) on older waveforms. Accumulated display is useful when observing jitters and temporary turbulence in waveforms.
  • Page 45 2.4 Waveform Acquisition and Display Conditions X-Y Waveform Display <For the setup procedure, see section 8.5> The relationship between the levels of two input signals can be observed by taking the level of the waveform assigned to the X-axis (horizontal axis) and the level of another waveform (whose display is turned ON) assigned to the Y-axis (vertical axis).
