VM4016 Command Dictionary 75
INPut:OFFSet
Purpose
Sets the input threshold for a group of channels
Type Setting
Command Syntax
INPut:OFFSet <voltage_level>,<channel_list>
Command Parameters
<voltage_level> = +9.96 V to -10.00 V.
<channel_list> = standard channel list syntax supporting channels 1 to 16.
*RST Value
0.496V for all channels
Query Syntax
INPut:OFFSet? <channel>
Query Parameters <channel> = 1 to 16
Query Response
ASCII numeric value from -10.00 to +9.96
Description The INPut:OFFSet command sets the input threshold for a channel or group of
channels, over which the input signal must cross to cause an interrupt event. This
command sets the value in the 8-bit DAC to which the input signal is compared. It is
important to note that the actual input offset value is affected by the INPut:RANGe
command, as the response has been normalized to ±10 V range. The actual input offset
for the allowable ranges are as follows:
Range Entered Threshold Actual Threshold
±10.0 x 1.0x
±100.0 x 10.0x
Examples Command / Query Response (Description)
INP:RANG 100,(@9:16) (Selects an input range of ±100 V for Channels 9 -
16)
INP:OFFS 2.5,(@9:16) (Selects an input threshold of 25 V for Channels 9
- 16)
INP:OFFS? 11 2.500 (Returns the set input threshold for Channel
11 of 25 V)
INP:RANG 10,(@1:8) (Selects an input range of ±10 V for Channels 1 -
8)
INP:OFFS 2.5,(@1:8) (Selects an input threshold of 2.5 V for Channels 1
- 8)
INP:OFFS? 5 2.500 (Returns the set input threshold for Channel
11 of 2.5 V)
