COM-1028 FSK/MSK/GFSK/GMSK modulator -> COM-2001 dual D/A conversion

The baseline configuration in the 1028_2001.stn settings file is as follows:
- 2-FSK modulation, 5 Mbits/s, modulation index 0.5, 0 Hz center frequency

(a) Connect a serial cable between the COM-1028 and a host computer.
(b) power up the assembly. From the ComBlock control center File|Import menu, 
import the settings file 1028_2001.stn 
(c) Using an oscilloscope, observe the COM-2001 output signals at the J1 (I-channel) 
and J2 (Q-channel) output SMA connectors.
The signals are sinewave segments, with phase transitions multiple of pi/2. 
The amplitude is 1.6V peak-to-peak, centered around 0.85V.
