| Yes. The labels are stored in the ASCII header file (*.hdr) of the waveform data and the header section of the file (*.asd) is saved in ASCII format. For example, if the waveform label is set to 'aaa,' then TraceName aaa is written in the header section. |
| Approximately 250 µs (the average of actual measured values) under the following settings:
16ch. 16 units of 701856 installed.
Memory length: 1 MW. T/div: 10 ms.
Sampling speed: 10 MS/s.
|
| 16-bit (8-bit x 2) data are taken to be one data point expressed in decimal notation. The data points are stored in one column. Convert/expand the values into binary values for viewing. |
| On the DL series, linear scaling is already applied to the waveform data. Thus, there is no information related to linear scaling in the header file. |
| The message "The Current module installation condition and the setup data are inconsistent. Will you initialize?" is displayed. The waveforms are displayed, but the channels that have different modules installed will not display the waveform correctly.
|
| For practical purposes, the answer is no. The channels that do not have input modules installed cannot be turned ON.Thus, even if waveform data could be loaded, the waveform cannot be displayed. |
| Since the DL708/DL708E supports large storage media through the built-in hard disk or SCSI interface and interconnectivity with PCs, functions used to segment files for saving and copying were not included. When saving data, you can specify the range to be saved by segmenting the data with the ZOOM function. When copying data, load the data first and use the method described above.
|
| All set-up conditions except the date, time, communications settings, and SCSI ID number are saved. |
| It is upwardly compatible. Data measured/saved by the DL708 can be loaded by the DL708E. Data measured/saved by the DL708E cannot be loaded by the DL708. |
| This is not possible. The reverse direction is not possible, either. |
| When using the auto file function of the action trigger to create files, the upper limit of files that can be created in one directory is 999. To save files beyond this limitation, upper-level directories must be created beforehand. If the upper-level directory (DIR1, 2, N) exists, the file save operation continues by changing the directory. |
| An FFT with 10000 computation points can only be specified using MATH1. You cannot specify an FFT with 10000 points using Math2 even if Math1 is turned OFF. In addition, the number of FFT points is common to Math1 and Math2. It cannot be set individually. |
| Up to 50 characters can be used. |
| The frequency bandwidth of the FFT performed on the DL708 is basically 1/2 the sampling rate. In other words, the frequency bandwidth that results from taking the FFT on the acquisition data sampled at 1 MS/s is 500 kHz. However, when the anti-aliasing filter is turned ON, the frequency bandwidth becomes 1/2.5 the sampling rate. |
| Data are measured continuously during the roll mode (no dead time). |
| It is reset by starting the measurement with the number of waveform acquisitions set to 0 shown in the lower left corner of the screen. (The value starts at 0 when the measurement is started after changing the settings such as the T/div setting.) |
| There is no problem in inputting a signal less than or equal to 1 Hz if the pulse width is greater than or equal to 1 µs. Sampling is performed on the rising edge of the signal.
|
| When the settings above are used, the display record length is 1 kW, but 4 MW of data are sampled. In this condition, the waveform cannot be reduced to display the entire display record length of data (1 MW). However, you can scroll and check the entire data. |
| You cannot change the T/div setting of a loaded waveform. Please use the ZOOM function for this task. |
| It depends on the module. Modules that provide the invert function (all other modules do not provide the invert function).

| The external trigger supports CMOS level signals. Thus, we only guarantee the range from 0 to 5 V. There is only a slight margin provided above 5 V in terms of maximum allowable input voltage. |
| CMOS (0-5 V input), 1.8 V-2.5 V (typical value). |
| 1st order Bessel for 500 kHz; 2nd order Bessel for other frequencies. |
| 600 Hz (-3 dB) when the filter is OFF. |
| The following models have been tested for compatibility:
Manufacturer: EXELTECH Inc. Model: XP250 series True sine wave AC output DC/AC inverter 250 W.
Distribution in Japan: DENRYO Co., Ltd. 2-85-5 Nishi-nibbori Arakawa-ku Tokyo (Denryo Building).
Note that the PROwatt series that are recommended for DL708Es cannot be used on the DL716. Due to the internal circuit used by the DL716 to control the harmonics of the power supply, inverters that output sine waves must be used for proper operation. Thus, the DL716 cannot use the PROwatt series, which output emulated sine waves.

|
| The number of directories that can be created is 4096. |
| The maximum speed is 135 Hz. This is the same concept as with the internal clock. |
| No. Always turn OFF the DL708 when removing or inserting input modules. |
| REX9530 by RATOC and PCSC-F by I/O Data have been tested for compatibility. The cards were tested on Windows 95 only. The use of the DL708/DL708E is restricted to Windows 95. Operations on Windows 3.1 have not been tested. |
| The power lamp starts blinking when the remaining amount of power falls to approximately 10 minutes of use. There is no function provided to check the amount of power remaining. |
| Yes. The cursor movement when the logic input module is used on the DL708/DL708E is as follows (this is applicable to Ver 2.03 or later.)
1) Marker cursor Only values related to the time axis (X+, Xx, dX, and 1/dX) are displayed. Y+, Yx, and dY values are not displayed (displayed as ***). The + and x markers are not displayed on logic signals.
2) H cursor All parameters are displayed as ***.
3) V cursor The cross point with the cursor is displayed in binary (01010000 11001111, for example). Parameters related to time, dX and 1/dX, are also displayed.
4) H&V cursor The V cursor here operates in the same fashion as the V cursor. The parameters of the H cursor here are not displayed (same as the H cursor). (The H cursor can be moved, but it does not affect the display in any way.)
|
| Yes. By saving the data recorded in real-time to the hard disk in AG format, the AG can load the data. |
| It cannot be used as is, because the protective cover gets in the way of the terminal insertion section. However, it can be used if you remove the protective cover. In this case, the use of the measurement lead is restricted to 42 V or less. Note that the protective cover has a divot that prevents the H and L to be reversed when the cover is put back. |
