8 Downloading Stimuli
8.1 Downloading Stimulus Files
After having set up the stimulus file, you can download the file to the connected STG. You can
select the channels that you want to download or download the complete file. The Sync
channel for synchronizing other devices connected to the Sync Out of the STG will always be
downloaded, you cannot deselect it.
You can start the stimulation directly after the download, or start it manually with the software
or hardware controls, or start it on a trigger. See also chapter "Operating the STG" for more
information.
Please note that the capacity of the 1000 series is limited. You will be notified during the
download by an error message when the maximum file size has been reached.
See also chapter "Batch Mode" for information how to run multiple files one after the other.
Warning: Check the file thoroughly before downloading it on the STG. The stimulus display is
independent from the worksheet and from the download. Verify that you download
only the
channels that you want to use. Do not start the STG if you are unsure about the channel
configuration or the nature of the downloaded file.
Warning: The stimulus length has to be the same on all channels. If you have programmed
stimuli with different time lengths, shorter stimuli will keep the last voltage or current value
until the complete stimulation has been finished on all channels. You will be notified by an error
message if this occurs. This behavior can lead to unexpected results and can even lead to
dangerous situations.
1. Select the channels for downloading under Download Channel.
2. On the STG menu, click either Download (sel.) to download only the selected channels onto the
STG or Downld. and Start (sel.) to download only the selected channels and start the
stimulation directly after the complete download. If you want to download all channels, you can
use the commands Download (all) or Downld. and Start (all). Be careful, because the channel
selection will have no effect in this case.
Disable/enable warning messages
Cancel this option to disable the message boxes displaying compiler warnings during stimulus
download.
The two error messages that can be disabled are: "warning: signal length shorter than the
maximum" and "warning: non zero last amplitude value". They may present a nuisance if you
download multiple stimulus files in batch mode.
• On the Settings menu, select or deselect Enable Compiler Warnings.
