Description
FMC High-Speed Data
Acquisition Board
Demonstrationcircuit1371,along with PScope™ software,
provides a USB based, Windows PC hosted digital data
acquisition system supporting high speed data converter
products from Linear Technology. The DC1371 must be
powered with the 5V power supply that is supplied with
the demo board. The PScope evaluation software auto-
matically detects the DC1371 and the demonstration cir-
cuit board connected to it. This system provides for fast
and easy performance evaluation of high speed ADCs.
DC1371 collects samples from high speed demonstra-
tion circuits and the PScope software performs various
analyses on the data including calculating SNR, SINAD,
THD, SFDR and ENOB. The digitized input, an FFT of the

respective owners.
collected data, the primitive wave of the sample set or an
IFFT of modified frequency domain data is plotted to a
display window to facilitate analyzing noise and distortion
products and their sources. Figure 1 shows a picture of
the DC1371. The DC1371 is connected to the ADC dem-
onstration circuit via a 400 pin FMC connector and to the
PC by a mini-USB cable.

Quick start proceDure
To prevent damage to the DC1371, it is important to follow
the equipment setup procedure outlined below:
1. Do not plug the DC1371 into the PC USB port before
running the PScope installation program.
2. Download the PScope installation program from http://
www.linear.com/designtools/software/
3. Run the PScope installation program and follow the on
screen instructions.
NOTE: The PScope evaluation software requires a PC
running Windows XP or newer, with an available USB
port.
4. Connect the DC1371 to a USB port and supply external
power to the DC1371. Only use the provided 5V power
supply.
5. The DC1371 should be provided with an ADC demo
board attached. This demo board should not be re-
moved. The DC1371 does not supply power to the ADC
demonstration circuit.
6. EachADCdemonstrationboardalsocomeswithademo
manual similar to this one and should be referred to
for specific usage details relevant to the demonstration
circuit being evaluated. Please refer to it for proper
jumper settings, input power requirements and input
signal levels and frequency ranges.
7. Apply an appropriate conversion clock and analog input
signal to the ADC demonstration board.
8. The PScope software will automatically find and con-
figure the DC1371 and the connected demo board.
