1 MHz Calibration Source

Post by Sam Wetterlin » Fri Jul 10, 2009 11:56 am

For anyone who has downloaded my calibration accessories file, note that there is a "typo" regarding the 1 MHz calibration source, which has now been corrected in the files on my website. The on-board DC reference voltage, which is used to determine the exact 1 MHz output level, is incorrectly stated in the schematic and on the PCB; it should be 0.5167 volts. I used a number of different resistor combinations before I finally settled on the final voltage divider.
