MAX19700 Evaluation Kit/Evaluation System
30) Set the analog input signal generators to output the
desired frequency. The amplitude of the generator
should produce a signal that is no larger than
4.5dBm as measured at the SMA input of the EV kit.
Insertion losses due to the series-connected filter
(steps 18 and 20) and the interconnecting cables
will decrease the amount of power seen at the EV
kit input. Account for these losses when setting the
signal generator amplitude.
31) Start the MAX19700 program by opening its icon in
the Start menu.
32) Normal device operation can be verified by the
“Status: Interface Board Operational” text in the
Interface box.
33) Click the POR Reset button on the MAX19700 EV
kit software GUI.
34) Enable the logic analyzer.
35) Capture data using the logic analyzer.
Tx DAC Setup
36) Ensure that a shunt is placed across pins 1 and 2
of jumper JU3.
37) Connect the clock signal generator to the input of
the clock bandpass filter.
38) Connect the output of the clock bandpass filter to
the EV kit SMA connector labeled J10.
39) Connect the output of the clock signal generator to
the data generator synchronization input.
40) Connect the first spectrum analyzer to the EV kit
SMA connector labeled J8 (Q channel).
41) Connect the second spectrum analyzer to the EV
kit SMA connector labeled J9 (I channel).
42) Connect the data generator to J11. See the Digital
Data Bit Locations section in this document for
header connections.
43) Turn on the -5V power supply.
44) Turn on all remaining power supplies.
45) Plug the CMOD232 wall cube into an electrical outlet.
46) Enable the signal generator.
47) Set the clock signal generator to output a 7.5MHz
signal. The amplitude of the generator should be
sufficient to produce a 16dBm signal at the SMA
input of the EV kit. Insertion losses due to the series-
connected filter (step 37) and the interconnecting
cables will decrease the amount of power seen at
the EV kit input. Account for these losses when set-
ting the signal generator amplitude.
48) Load the desired test pattern into the data genera-
tor. Data clocked on the rising edge of the clock is
transmitted to the Q channel. Data clocked on the
falling edge of the clock is transmitted to the I
channel.
49) Start the MAX19700 program by opening its icon in
the Start menu.
50) Normal device operation can be verified by the
“Status: Interface Board Operational” text in the
Interface box.
51) Click the POR Reset button on the MAX19700 EV
kit software GUI.
52) Enable the pattern generator.
53) Enable the spectrum analyzers.
54) Analyze the data on the EV kit outputs (J8 and J9)
with the spectrum analyzers.
