[SENSe:]DIGital:THReshold
Syntax
[SENSe:]DIGital:THReshold {<voltage>|MIN|MAX|DEF}, (@<ch_list>)
[SENSe:]DIGital:THReshold? [{MIN|MAX},] (@<ch_list>)
Description
This command sets the input threshold voltage for digital input operations on the 34950A Digital I/O Module. You can send this command at any time, but the setting applies only to input channels.
Used With:
34950A Digital I/O Module
Parameters

Name |
Type |
Range of Values |
Default Value |
|
<voltage> |
Numeric |
Desired threshold voltage between 0V and 5V, with 20 mV resolution. MIN = 0V, MAX = 5V |
0.8V (TTL) |
|
<ch_list> |
Numeric |
One or more digital input channels in the form (@sccc).
|
This is a required parameter |
Remarks
The selected threshold voltage applies to the specified channel, independent of the current channel width (see CONFigure:DIGital:WIDTh command.
The selected threshold voltage is stored in volatile memory and will be set to 0.8V when power is turned off or after a Factory Reset (*RST command).
Return Format
The query command returns the threshold voltage in the form "+1.00000000E+00" for each channel specified. Multiple responses are separated by commas.
Examples
The following command sets the threshold voltage to 1.8V on channels 101 and 103 on the module in slot 3.
DIG:DATA:THR 1.8,(@3101,3103)
The following query returns the threshold voltage settings on channels 101 and 103 on the module in slot 3.
DIG:DATA:THR? (@3101,3103)
Typical Response: +1.80000000E+00,+1.80000000E+00
