波形產生器 - 常見問題

1. 請問 PC 要如何透過 USB 來控制 G5100A？

只須到 NI 的網站 www.ni.com - NI-VISA 下載驅動程式後，開機接上 USB，PC 成功辨識 G5100A，就可以透過本公司的應用軟體 Wavepat 或是自己編寫程式，來控制 G5100A 了。

2. 請問要如何用 G5100A 產生只有直流的電壓位準？

PICOTEST G5100A can output DC voltage in the range of -5 V DC to +5 V DC (into a 50-ohm termination).

To output a DC voltage from a G5100A:

1. Press [Utility] and choose “DC ON”.

2. Press soft-key [Vos] to activate the DC mode with the offset voltage as the output level. (0V default)

3. Using the knob or numeric keypad to modulate the level you desired.

4. press normal function keys to return to normal waveform operation.

3. 如何才能將 G5100A 的警告音及操作音關閉？

在 G5100A 的韌體版本1.6(含)前只有關閉系統警告音，而不能關閉操作時的聲音。只有韌體版本1.7以上才可以分別關閉系統警告音及操作音。以下是音效開/關步驟。

1. Press [Utility] and choose “System”.

2. Press soft-key [Sound] to on/off the sound of operation keys or press [Beep] to on/ off the warning beep.

3. Press [DONE] back to normal operation.

4. 何處可以取得 G5100A 的應用程式及使用手冊等資料？

所有的資料您都可以從附在儀器中的光碟片中取得，或者您可以到 PICOTEST 網站的技術支持頁面下載儀鼎儀器所有最新版的應用軟體程式、韌體更新程式或使用手冊等資料。

5. 如何使用 Pattern Output 功能？

G5100A waveform generator provides the capability of outputting a specified pattern of up to 256k points in 16-bit resolution. Similar to arbitrary waveforms, pattern output provides five built-in patterns and up to four user-defined patterns that are stored in non-volatile memory. The built-in patterns are exponential-rise, exponential-fall, negative-ramp, sinc, and cardiac. The default pattern output is an exponential-rise wave.

You may use the Wavepatt®, waveform and pattern editor to create the patterns you want or import the waveforms from the oscilloscope that you captured previously and follow below steps to set up pattern output.

1. Press the Utility button to enter the utility menu.

2. Press the softkey under [PATT MODE] to enter the PATTERN menu.
   

3. Press the softkey under [Fclk/Perd] to toggle between [Fclk] (frequency) and [Perd] (period).
   

4. Press the softkey under [Start Addr]/ [End Addr] for setting the start /end point of the pattern to output. Use the knob with the cursor keys to change the value. Or use the numeric keypad to enter a new value and then press [Enter] to finish the entry or the press [Cancel] to withdraw the changes.
   　

5. Press the [Select wform] to enter selection menu:

   1. Press [Built In] and choose the desired pattern from the five built-ins by pressing the corresponding softkey.

   2. Press [Saved Wform] and choose the desired user-defined pattern by pressing the corresponding softkey.

   3. One may delete a user-defined pattern by pressing the softkey under Delete Store and choose the pattern to delete by pressing the corresponding softkey
      

6. Press the [Output Setting] and then press [RPT.] to toggle between ON and OFF to enable/disable repeating output of the pattern.
   

7. To configure the trigger setting, press [Trig Setup] to enter the trigger setup menu:

   1. To specify the trigger source, press the softkey under Src and then select among Ext (external) and Man (manual).

   2. If manual trigger is selected, you may configure the trigger out signal by pressing the softkey under Trig Out and then select among OFF, rising-edge trigger and falling-edge trigger.

   3. If external source is selected, you may press the softkey under Slope to toggle between rising edge trigger and falling edge trigger.

   4. Press the softkey under DONE to finish the trigger setting.

8. After completed above setting. Press function key [Output] to generate the pattern out. The pattern would be outputted once only if the setting of [RPT.] is OFF in the [Output Setting].
