row header labeled “UWIRE” as shown in Figure 5.
Align the arrows on the two boards to ensure
proper orientation. JP1 should have a jumper
installed on the main board to provide power to the
PIC microcontroller board. Lastly, flip the switches
on the PIC microcontroller board to the following
positions: Switch 1 = OFF, Switch 2 = OFF.

by board-edge SMA(f) connectors labeled “INA”
and “INB”. The input impedances are 50 ohms.
The maximum amplitude (Vp-p) for satisfactory
performance is 1 Vp-p. The inputs are DC-coupled
but the input signal may be either DC or AC
coupled. If DC coupled, the DC level of the signal
should not exceed 1.2 V. The DC level is set on
the ADC14DS105KARB reference board. Connect
the signal source through the SMA connector as
shown in Figure 1 and Figure 4. Recommended
signal generators are the HP8644B (HP/Agilent) or
the SMA100A (Rohde & Schwarz). A bandpass
filter between the signal generator output and the
ADC14DS105KARB SMA connector is required to
measure the true performance of the board. See

signal generator amplitude will need to be adjusted
during evaluation to obtain the desired signal
amplitude at the ADC input.
