8.7.4 Descriptions of selectable signals
• hiwhenA ”high when wave A is played” is useful in alternate mode, or when waveform B
is selected and a high level is applied to the AUX terminal. Logic level LO corresponds
to waveform B, logic HI corresponds to waveform A. The tparity choice is based on the
triggers processed and not on the waveform selection.
traces: red = hiwhenA, yellow = trigger , green = RF, blue = tparity
• gate ”ON during RF signal” the gate signal is at high when the RF signal is generated:
it comes HI on the delayed trigger and goes to LO after the RF cycle has completed. It
comes slightly earlier than the RF signal

. /gate is negated gate.

the generation delay varies with the sampling frequency.
