COM-5002 LAN/TCP-IP Network Interface
  -> COM-8001 Arbitrary Waveform Generator
    -> COM-2001 Dual D/A conversion

Test objective: Load a file containing two identical sinewave samples (I & Q channels).
Playback the file into a dual D/A converter.
Check the waveform purity using an oscilloscope.

The ComBlock assembly IP address is configured to be 172.16.1.128
If this IP address does not match your network, edit the 5002_8001_2001.stn file
(change the COM-5002 registers 0-3 [IP address].

Proper operation can be verified as follows:

(a) connect a serial cable between the host PC and the DB9 connector of the COM-5002

(b) connect a COM-5002 to the LAN. 

(c) connect two coaxial cables between the COM-2001 output and a dual trace oscilloscope.

(d) import the 5002_8001_2001 configuration file

(e) using the ComBlock Control Center Functions | Pattern Generator, 
upload the file "sine_wave_I_Q_2560.txt" (same directory as the 5002_8001_2001.stn settings file).
The file contains samples in DECIMAL format. Do the entire upload, starting at address 0.
Select Action = Start Upload. Then Apply.
The menu should show a quick progress bar, then indicate upload completion with 2560 bytes uploaded.
(f) using the ComBlock Control Center Functions | Pattern Generator, 
download the file. The data is 'pushed', at a rate of 200Ksamples/s, with 20 bit output width.
Select Action = Start continuous download. Then Apply.
The oscilloscope should show two perfect sinewaves of amplitude 1.5Vpp.
