AC amplitude correction is only possible when

reference oscillator frequency is 42.94967296 MHz, either internal or
external. CALibration:STATe:AC

reference oscillator frequency is selected.
The HP E1340A uses an active amplitude correction technique,
boosting the output signal to compensate for filter and other
roll-offs. When waveform generation at high frequencies is
halted either because ARM:LAYer1:COUNt cycles have been
generated, or because an ABORt command was executed, filter
loss disappears, and the output level may exceed the level
specified by SOURce:VOLTage:LEVel:IMMediate:AMPLitude. It
is recommended that AC amplitude correction be used only for
continuous output.
