SERIES EL 022013
B-19
Description: List Power FET Modules within chassis (see below for example).
B.105 SYSTem:PFModule:STATus? QUERY
SYST:PFM:STAT?
Syntax: Short Form: SYST:PFM:STAT? Long Form: SYSTem:PFModule:STATus?
Description: Show FET channel temperature and fuse status (see below for example).
Below is a response to SYST:PFM:STAT? for a 2 PFM Load when the load is drawing 52 Amperes.
Note that these are not highly accurate current measurements but rather are intended to show system
status such as the distribution of current (and therefore power) between the FETs. In the example
below, the top row is the second set of FETs and the bottom row is the first row of FETs. The Currents
are for FETs in each of the four positions as viewed from the front.
Below is an example showing illustrating a Fuse blows on the PFM.
