Command Syntax

INPut:OFFSet <voltage_level>,<channel_list>

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Command Parameters

<voltage_level> = +9.96 volts to -10.00 volts.

 

 

 

 

 

 

<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:
