with engineering prefixes.
Value coupling
Range coupling With high level, see page 72
*RST value –500 mV
Specified limits –10.0 V to 9.9 V (50
Ω
into 50
Ω
)
Description Use this command to program the low level voltage of the OUTPUT
signal. Note that to set the OUTPUT levels in terms of voltage, you first
have to execute the
[:SOURce]:HOLD VOLTage
command to enable the
[:SOURce]:VOLTage
subsystem.
The available voltage range is limited by the combination of:
• Specified current limits
• Actual OUTPUT impedance setting
:OUTPut:IMPedance
• Actual expected load impedance setting
:OUTPut:IMPedance:EXTernal
Example To set the low level voltage:
High–Low
2
Offset =
Amplitude = High – Low
:HOLD VOLT
:VOLT:LOW 500MV
Enable VOLTAGE subsystem
Set OUTPUT low level to 500mV
