  • Page 26: Vertical And Horizontal Axes

    Vertical Position of the Waveform <For the setup procedure, see section 5.3> Since the DL7400 is capable of displaying 8 channels (4 channels on the DL7440) of input waveforms, the waveforms may overlap making them difficult to be observed. In this case, you can change the display position of waveforms along the vertical axis (vertical position) in the range of ±4 divisions for easier viewing.
  • Page 27 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 28 2.2 Vertical and Horizontal Axes Offset Voltage <For the setup procedure, see section 5.6> When observing a voltage riding on top of a predetermined voltage, an offset voltage can be applied to eliminate the predetermined voltage so that only the changes in the signal can be observed with higher vertical axis sensitivity.
  • Page 29 2.2 Vertical and Horizontal Axes Horizontal Axis (Time Axis) Selecting the Time Base <For the setup procedure, see section 5.11> By default, the sampling timing of the measured waveform is controlled by the internal clock signal generated from the time base circuit within the DL7400 (see the block diagram in section 1.1).
  • Page 30 2.2 Vertical and Horizontal Axes Relationship between the Specified Record Length, Time Axis Setting, Sample Rate, and Display Record Length If you change the time axis setting with respect to the specified record length of the acquisition memory, the sample rate and display record length change. (For more details about this relationship, see appendix 1.
  • Page 31 2.2 Vertical and Horizontal Axes Time Axis Setting and Roll Mode Display If T/div is set to a certain range (see appendix 1), the waveforms are displayed in roll mode. In roll mode, the displayed waveform is not updated using triggers (update mode).

  • Page 32: Trigger

    Trigger A trigger is a cue used to display the waveform on the screen. The trigger is activated when the specified trigger condition is met. At this point, the waveform is ready to be displayed on the screen. Trigger Source, Trigger Slope, and Trigger Level Trigger Source Trigger source refers to the signal that is used in checking the trigger condition.
  • Page 33 2.3 Trigger Enhanced Trigger Multiple conditions or a special-purpose condition can be specified as a trigger condition. A->B(N) Trigger <For the setup procedure, see section 6.8> A trigger is activated the n time condition B becomes true after condition A has become true.
  • Page 34 2.3 Trigger Pattern Trigger <For the setup procedure, see section 6.10> With pattern triggers, the trigger source is set to multiple signals. A trigger is activated when all of the trigger conditions of the trigger sources are met or when the trigger conditions are no longer met.
  • Page 35 2.3 Trigger OR Trigger <For the setup procedure, see section 6.12> A trigger is activated when any of the edge or window conditions specified on each channel are met. For example, a trigger can be activated on the rising edge of CH1 or CH2.
  • Page 36 2.3 Trigger Logic Trigger <For the setup procedure, see section 6.15> The DL7400 has two logic probe input connectors, A and B. Each pod can receive 8 bits of logic signals. A trigger is activated on the rising or falling edge of the clock bit while the condition consisting of the combination of H, L, and Don’t Care of Pod A and B (16 bits) is met.
  • Page 37 2.3 Trigger Single (N) Mode Waveforms are acquired and stored in different memory areas each time a trigger is activated the specified number of times. Then, acquisition is stopped, and all the acquired waveforms are displayed. For details on the acquisition method of waveforms in Single (N) mode, see “Sequential Store”...
  • Page 38 2.3 Trigger HF Rejection <For the setup procedure, see sections 6.5, 6.8 to 6.12> Turn HF rejection ON when eliminating high frequency components above 15 kHz or 20 MHz from the trigger source. This prevents triggers from being activated at unexpected points due to the effect of high frequency noise.

  • Page 39: 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, 8 MW, and 16 MW.
  • Page 40 2.4 Waveform Acquisition and Display Conditions Envelope Mode In normal mode and averaging mode, the sample rate (the number of times data is acquired per second in the acquisition memory) drops if T/div is increased (see appendix 1). However, in envelope mode, the maximum and minimum values are determined from the data sampled at 1 GS/s or 800 MS/s at time intervals one half that of the sampling period (inverse of the sample rate) of normal mode regardless of the interleave mode setting (ON or OFF).
  • Page 41 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 42 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), Hexa (six divisions), and Octal (eight divisions, DL7480 only) Waveform Mapping...
  • Page 43 2.4 Waveform Acquisition and Display Conditions Zooming the Waveform <For the setup procedure, see section 8.4> The displayed waveform can be expanded along the time axis. This function is useful when the waveform acquisition time is set long and you wish to observe a particular section of the waveform closely.
  • Page 44 2.4 Waveform Acquisition and Display Conditions Snapshot and Clear Trace <For the setup procedure, see section 8.6> Snapshot When the trigger mode is set to a mode other than Single or Single (N), the displayed waveforms are periodically updated or displayed in roll mode. By using the snapshot function, you can temporarily hold the waveform (snapshot waveform) that would be cleared when the screen is updated on the screen.

  • Page 45: Waveform Computation

    Phase Shift <For the setup procedure, see section 9.8> The phase of the waveform of CH1 to CH4 on the DL7440 and CH1 to CH8 on the DL7480 can be shifted and displayed. The phase shifted waveform is used in the computation (computed waveform).
  • Page 46 2.5 Waveform Computation Power Spectrum Computation <For the setup procedure, see section 9.6> The power spectrum of the input signal can be computed and displayed by taking the FFT (Fast Fourier Transform). This is useful when you wish to check the frequency distribution of the input signal.
  • Page 47 2.5 Waveform Computation User-Defined Computation (Optional) <For the setup procedure, see section 9.9> You can define computing equations by combining the following operators: +, –, *, /, ABS (absolute value), SQRT (square root), LOG (logarithm), EXP (exponent), NEG (negation), SIN (sine), COS (cosine), TAN (tangent), ATAN(arc tangent), PH (phase), DIF (differentiation), DDIF(2nd order differentiation), INTG (integration), IINTG(double integration), BIN (binary computation), P2 (square), P3 (cube), F1(...

  • Page 49: Analyzing And Searching Waveforms

    Analyzing and Searching Waveforms Displaying History Waveforms <For the setup procedure, see section 10.1> Past waveform data (history waveforms) stored in the acquisition memory can be displayed when waveform acquisition is stopped. You can display a specified history waveform from the data (up to 4096 waveforms, or the number of triggers) stored in the acquisition memory.
  • Page 50 2.6 Analyzing and Searching Waveforms Search & Zoom When waveform acquisition is stopped, you can search the displayed waveforms (within the display record length. See appendix 1.) and display the waveforms that match the search conditions expanded on the screen. Edge Search <For the setup procedure, see section 10.4>...
