The default factory configuration is 3Vp-p amplitude with 3:1 ratio (1Vp-p for low signal.)
Repeat steps 3-5 for OUTPUTS 2 through 4 using the following potentiometers for amplitude and ratio:

N.1 Frequency Synthesizer (87-8022)
The N.1 Frequency Synthesizer card's four independently programmable outputs generate frequencies
from 1 PPS to 50 MPPS, with a tuning resolution of 1 PPS. The N.1 module outputs are independently
frequency locked to the XLi's internal oscillator. Therefore the N.1 outputs have the same frequency
accuracy and long term stability of the XLi's internal oscillator.
The N.1 Frequency Synthesizer is configured from the front panel keypad and command line interface
using F120 - N.1 Frequency Synthesizer (page
