[Elecraft] KPA500 WS power resolution

[ANDY DURBIN]

The KPA500 provides the ^WS; serial interface interrogation which returns output power and SWR.  The power and SWR are reported for STBY and OPER modes.   In OPER mode the power seems to have a resolution of 1 Watt.  In STBY, if I increment my drive power in 1 Watt steps the power reported by ^WS;  jumps from 30 to 40 with no intermediate steps.


WS pwr  LP100 pwr

00            24.9

10            25.8

25            29.4

25            28.7

30            29.8

30            39.6

40            40.3


Is this very low resolution of WS power in STBY mode intentional? (firmware 1.54).


Thanks,
