[SENSe:]COUNter:THReshold:VOLTage
Syntax
[SENSe:]COUNter:THReshold:VOLTage {<voltage>|MIN|MAX|DEF}, (@<ch_list>)
[SENSe:]COUNter:THReshold:VOLTage? [{MIN|MAX},] (@<ch_list>)
Description
This command sets the input threshold voltage for the specified counter channels on the 34950A Digital I/O Module. Changing the threshold voltage while an initiated measurement is in progress (see [SENSe:]COUNter:INITiate command) is not allowed.
Used With:
34950A Digital I/O Module
Parameters

Name |
Type |
Range of Values |
Default Value |
|
<voltage> |
Numeric |
Desired threshold voltage between 0V and 3V, with 20 mV resolution. MIN = 0V, MAX = 3V |
0.8V (TTL) |
|
<ch_list> |
Numeric |
One or more counter channels in the form (@sccc).
|
This is a required parameter |
Remarks
If you change the threshold voltage while a totalizer operation is in progress, the count on the specified channels will be cleared.
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 counter channels 301 and 302 on the module in slot 3.
COUN:THR:VOLT 1.8,(@3301,3302)
The following query returns the threshold voltage settings on counter channels 301 and 302 on the module in slot 3.
COUN:THR:VOLT? (@3301,3302)
Typical Response: +1.80000000E+00,+1.80000000E+00
