45 BURST Signal input/output for controlling the burst ramp.
For two-path instruments, the signal for Path B can be applied to one of the
USER interfaces.
With external envelope curve control ("Custom Digital Modulation" only), the
pin is the input for the control signal "BURST_RAMP".
With internal envelope curve control, the control signal "BURST_RAMP" is
output for Path A.
46 EXT TUNE Tuning input for the internal reference frequency.
47 BITCLK Output Bit clock for internal mode.
For two-path instruments, the signal for Path B can be applied to one of the
USER interfaces.
48 USER 2 USER input/output which can be configured for various purposes.
49 SYMBCLK Symbol clock output for internal mode.
With two-path instruments, the signal for Path B can be applied to one of the
USER interfaces.
