AUTO FUNCTIONS
AGAN The AGAN command performs the Auto Gain function. This command is
the same as pressing the [Auto Gain] key. Auto Gain may take some
time if the time constant is long. AGAN does nothing if the time constant
is greater than 1 second. Check the command execution in progress bit
in the Serial Poll Status Byte (bit 1) to determine when the function is
finished.
ARSV The ARSV command performs the Auto Reserve function. This com-
mand is the same as pressing the [Auto Reserve] key. Auto Reserve
may take some time. Check the command execution in progress bit in
the Serial Poll Status Byte (bit 1) to determine when the function is
finished.
APHS The APHS command performs the Auto Phase function. This command
is the same as pressing the [Auto Phase] key. The outputs will take many
time constants to reach their new values. Do not send the APHS com-
mand again without waiting the appropriate amount of time. If the phase
is unstable, then APHS will do nothing. Query the new value of the phase
shift to see if APHS changed the phase shift.
AOFF i The AOFF i command automatically offsets X (i=1), Y (i=2) or R (i=3) to
zero. The parameter i is required. This command is equivalent to press-
ing the [Auto Offset] keys.
