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).

Sorry, there was a typo in the table. It should read:
WS pwr LP100 pwr 00 24.9 10 25.8 25 26.4 < 25 28.7 30 29.8 30 39.6 40 40.3 73, Andy k3wyc ________________________________ From: ANDY DURBIN <[hidden email]> Sent: Friday, May 18, 2018 10:40 AM To: [hidden email] Subject: KPA500 WS power resolution The KPA500 provides the ^WS; serial interface interrogation which returns output power and SWR.

It seems that at least one person was confused by my data. Let me try again, this time including data for each step rather than just the data that bracketed the WS power transitions:
LP-100A WS 24.9 00 25.8 10 26.4 25 28.7 25 29.8 30 33.4 30 33.9 30 34.6 30 35.8 30 36.5 30 37.7 30 38.4 30 39.6 30 40.3 40 The question remains the same. Is the low resolution of WS indicated power intended? 73, Andy k3wyc ________________________________ From: ANDY DURBIN <[hidden email]> Sent: Friday, May 18, 2018 10:47 AM To: [hidden email] Subject: Re: KPA500 WS power resolution Sorry, there was a typo in the table.
