:POWer Commands
:POWer:ONOFf:THResholds
Command Syntax
:POWer:ONOFf:THResholds <type>,<input_thr>,<output_thr>
<type> ::= {ON | OFF}
<input_thr> ::= percent from 0-100 in NR1 format
<output_thr> ::= percent from 0-100 in NR1 format
The :POWer:ONOFf:THResholds command specifies the input and output
thresholds used in the Turn On/Turn Off analysis.
Turn On analysis determines how fast a turned on power supply takes to reach
some percent of its steady state output. Turn on time is the time between T2 and
T1 where:
• T1 = when the input voltage first rises to some percent (typically the 10%
threshold) of its maximum amplitude.
• T2 = when the output DC voltage rises to some percent (typically the 90%
threshold) of its maximum amplitude.
Turn Off analysis determines how fast a turned off power supply takes to reduce its
output voltage to some percent of maximum. Turn off time is the time between T2
and T1 where:
• T1 = when the input voltage last falls to some percent (typically the 10%
threshold) of its maximum amplitude.
• T2 = when the output DC voltage last falls to some percent (typically the 10%
threshold) of its maximum amplitude.
Query Syntax
:POWer:ONOFf:THResholds? <type>
The :POWer:ONOFf:THResholds? query returns the input and output threshold
settings for the turn on/turn off analysis type.
Return Format
<input_thr>,<output_thr><NL>
<input_thr> ::= percent from 0-100 in NR1 format
<output_thr> ::= percent from 0-100 in NR1 format
