Issue number| SK-1606
---|---
Models affected| AFG31XXX
Symptom| Double Pulse App: The width and gap values in the double pulse app table did not update the waveform in real-time until the focus was lost.

Known problems

commands, channel 1 and channel 2 will not trigger at the same time.
Workaround| Enter Basic Mode and align phase as well as set CH2 phase equal to CH1 before returning to advanced mode
Issue number| SK-1675
Models affected| AFG31XX2
Symptom| When setting a burst on both channels with channel 2 set to output immediately following channel 1, i.e. CH2 trigger delay = CH1 trigger interval, and with the waveform is set to last exactly as long as the trigger interval, according to the cycle count and frequency, The AFG will miss every second burst of channel 2.
Workaround| Reduce cycle count of channel 2 or decrease channel 2’s trigger interval.

Installation instructions

You can use the front-panel USB Type A connector to update your instrument firmware using a USB flash drive. This task is done using the front-panel touchscreen.
CAUTION. Updating your instrument firmware is a sensitive operation; it is critical that you follow the instructions below. If you do not, you may cause damage to your instrument. For example, to prevent damage to the instrument, do not remove the USB flash drive at any time while updating the firmware, and do not power off the instrument during the update process.

To update your instrument firmware:

1. Visit tek.com and search for the Series 31000 firmware.

2. Download the compressed .zip file to your computer.

3.  Unzip the downloaded file and copy the .ftb file to the USB flash drive root directory.

4.  Insert the USB in the AFG31000 Series instrument front panel.

5. Press the Utility button.

6.  Select Firmware > Update.

7. Select the USB icon.
   

8. Select the file that you are using to update your instrument.

9. Select OK. You will see a message asking to confirm this update.

10.  Verify that the instrument powered off and powered on to install the update.

11.  Remove the USB drive.
    NOTE. When using InstaView, each time a cable is changed, the firmware is upgraded, or the instrument is power-cycled, the cable propagation delay must be auto-measured or manually updated to make sure InstaView works properly.
