I remotely changed my 8648X modulation from Pulse to AM, but the display still indicates 'PULSE'. Is the 8648X outputting an AM or PM modulation?

The AM modulation is activated now. An example of a workaround to correct the annotation is by the program below:

AM:STAT ON
AM:STAT OFF
PULM:STAT ON
PULM:STAT OFF
OUTP:STAT OFF
FM:STAT ON
FM:STAT OFF
OUTP:STAT ON
AM:STAT ON

Since this product has been discontinued, there is no plan to release new firmware to fix this bug. The program above will turn off the 'PULSE' indicator on the 8648X display.
