23 :MEASure Power Commands
:MEASure:RDSon
(see page 1428)
Command Syntax
:MEASure:RDSon [<source1>][,<source2>]
<source1>, <source2> ::= {CHANnel<n>| FUNCtion<m> | MATH<m>
| WMEMory<r>}
<n> ::= 1 to (# analog channels) in NR1 format
<m> ::= 1 to (# math functions) in NR1 format
<r> ::= 1 to (# ref waveforms) in NR1 format
The :MEASure:RDSon command installs a power Rds(on) measurement on screen.
Rds(on) is the ON resistance between the drain and source of MOSFET. The
Rds(on) characteristic is also published in the switching device data sheet.
Query Syntax
:MEASure:RDSon? [<source1>][,<source2>]
The :MEASure:RDSon? query returns the measured Rds(on) value.
Return Format
<return_value><NL>
<return_value> ::= the VCE(sat) value in NR3 format
