channels: <number>
output mode: <mode>
format: <format number>
Make sure you define the total number of channels for the used STG properly (4 channels for an
STG with 4 channels, 8 channels for an STG with 8 channels, and so on), according to the
software version. You can select the maximum number of channels during the installation of
MC_Stimulus. On the Help menu, click About MC_Stimulus to check your current software
version.
Example:
You have to include the following line in the ASCII file if you have installed MC_Stimulus for
STG1004.
channels: 4
Output mode is either voltage or current.
Example:
output mode: voltage
Three different format types are available: 1, 2, 3.
Example:
format: 3
Data
Preceding the data, the output channel number has to be specified by the following line.
channel: <channel number>
You can specify analog output channels from 1 to 8 (limited by the number of analog output
channels of the connected STG, of course).
The digital Sync Out channel number directly follows the maximum number of output channels.
For example, if you have installed MC_Stimulus for 4 channels, the Sync Out channel is channel
number 5; if you have installed MC_Stimulus for 8 channels, the SyncOut channel is channel
number 9.
The data follows after the channel specification line; three format types are available. All format
types follow the MC_Stimulus worksheet's structure of rows and columns. See the description of
the worksheet for more details. Columns are separated by blanks or tabs. The first line has to
contain the column headers. The following lines contain the voltage/current and time values.
Rows/lines are separated by a carriage return or line feed (CR/LF). This is the Windows standard
control character inserted when you press the ENTER key.
The voltage unit is mV and the current unit is μA. Please make sure that all values are in the
ranges specified for the STG you use. For the Sync Out channel, only values of 0 and 1 are allowed.
The time unit is μs. Time values can be in the range from 20 to 18.000.000.000 (20μs to 5 h). Time
base of the STG is 20μs, so only times that are multiples of 20μs are valid.
Note: Please make sure that there are no additional tabs or characters, which would lead to an
error message. Show tabs and spaces in your text editor and check the file before importing it.
