Printer Port Records
Digital Waveforms - 06/18/98 EDN Design Idea (File
includes several circuitsscroll to find this one) To record or capture special waveforms, thOse that
appear once or have no fixed frequency, the usual technique is to use a logic analyzer or a storage
OscillOscope. However, these tools are very expensive. Moreover, because of limited memory, a storage scope
can record fewer than 1000 samples. The technique presented here provides an alternative method to recording
digital waveforms. The idea is to use the PC's printer port to sample waveforms, and the PC's memory to store
data. . . . [by Dean Shen, Dycam Inc, Chatsworth, CA]
PScope: High-Speed ADC Data Collection Software - When provides a customer with a high speed ADC demo board we also provide PScope, the
software to evaluate the demo board. PScope is a simple software package that can collect, and display data
from high speed ADC demo boards. It will also provide a simple and easy way to measure the key performance
parameters . . . [Linear Technology App Note - , Clarence Mayott Jan 4th 2011]

Remote Digital Thermometer Sends Data over AC
Power Line - This circuit is intended for precision
centigrade temperature measurement, with a transmitter section converting to frequency the sensor's output
voltage, which is proportional to the measured temperature. The output frequency bursts are conveyed into the
mains supply cables. The receiver section counts the bursts coming from mains supply and shows the counting
on three 7-segment LED displays. The least significant digit displays tenths of degree and then a 00. 0 to
99. 9 °C range is obtained. Transmitter-receiver distance can reach hundred meters, provided both units are
connected to the mains supply within the control of the same light-meter. . . . [Flavio Dellepiane's web

Designing a Band-Pass Filter for Narrow-Band, High IF, 16-Bit, 250 MSPS Receiver Front End
- The modified AD9467-250EBZ board contains the circuit evaluated as
described in this note, and the HSC-ADC-EVALCZ data capture board is used in conjunction with VisualAnalog
evaluation software, as well as the SPI controller software to properly control the ADC and capture the data.
Application Note AN-835 contains complete details on how to set up the hardware and software to run the tests
described in this circuit note. . . . [Analog Devices-Circuits from the Lab]
RS-232C handshake lines transfer data frame - 10/23/97 EDN Design Idea The asynchronous RS-232C interface is a simple, low-cost option
for interconnecting processor-based systems, but this character-oriented interface supports no direct
mechanism to transfer variable-sized messages as self-contained. . . [by SK Shenoy, Naval Physical &
