4.12.1.6 Predefined Voltage Levels
This command is used to set the pulse voltage levels to predefined values. Four predefined values are
available as follows:
CMOS: High level 5V; Low level 0V
TTL:
High level 2.4V; Low level 0.4V
ECL: High level –0.8V; Low level –1.8V
USER: User-defined levels, as set using the PHIGH and PLOW commands
COMMAND TYPE: Setting only
SETTING
Syntax: [:SOURce]:VOLTage[:LEVel][:IMMediate]:PREDefined
Arguments:
Type: Character
Options: CMOS, TTL, ECL, USER
Examples: :VOLT:PRED ECL
4.12.1.7 High Voltage Limit
This command is used to set the high limit of the pulse.
COMMAND TYPE: Setting or Query
SETTING
Syntax: [:SOURce]:VOLTage:LIMit:HIGH[units]
Arguments:
Type: NRf
Units: MV, V (default)
Range: -9.5V to +10V
