COM-3004 20 - 90 MHz receiver -> Multi-path simulator COM-1024 -> Dual D/A converter COM-2001

The baseline configuration in the 3004_1024_2001.stn settings file is as follows:
70 MHz center frequency
200 MHz DDS processing clock.
Internal 40 MHz frequency reference.
-64 dBm input level threshold for full scale 10-bit A/D conversion.
External PLL-STROBE frequency hopping signal disabled.
Multi-path: 
one path with no frequency offset, no delay, no attenuation (Initially enabled)

Purpose: test the RF receiver module in presence of an input sinewave.  
Check the multipath simulator.
Convert the multi-path signal back to analog.

(a) Turn the power supply on. Import the 3004_1024_2001.stn setting file into the assembly 
(from the ComBlock Control Center  File | Import menu).

(b) connect an RF frequency generator to the RF-IN input. 
Set the frequency to 71 MHz, level -64 dBm. 
Note 1: as the COM-1024 is not designed to control AGC, any input signal level above -64 dBm
may cause saturation.

(c) using an oscilloscope, probe the COM-2001 I and Q outputs. The capacitors C3 and C24
are convenient test points. The signals should be 1 MHz sinewaves, 90 degrees out of phase with respect
to one another, and with amplitude of 1Vpp.
