Waveform Generator - FAQ

1. How do I connect the G5100A to a PC via the USB port?

All you need is download NI-VISA or NI-VISA Run-time Engine from www.ni.com/visa and follow below steps.

  1. Install NI-VISA or www.ni.com - NI-VISA Run-time Engine
  2. Using an USB cable to connect the PC and G5100A.
  3. Switch on the instrument and the PC will recognize G5100A automatically.

2. How do I generate a DC voltage output from the PICOTEST G5100A?

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. How to turn off the sound of G5100A?

In G5100A, only firmware version 1.7 or excess version support “sound off” function or it can only support “ Beep off”.

  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. How do I get Instrument manual and application software for G5100A?

All of the application software and manuals are typically shipped on a CD with the instrument. You may also the latest update of the software, firmware and manuals in PICOTEST website on the Support page.

5. How do I set up pattern out?

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].
