DEMO MANUAL DC2049A
QUICK START PROCEDURE
DC2049A is easy to set up to evaluate the performance of
the LT3999EMSE. Refer to Figure 1 for proper measure-
ment equipment setup and follow the procedure below:
1. Connect Load 1 (positive) between the VOUT1 and GND
terminals and another Load 2 (negative) between the
VOUT2 and GND terminals.
2. With power off, connect the input power supply to the
+VIN and –VIN terminals.
3. Turn the input power supply on and make sure the
voltage is between 10V and 15.5V.
4. To measure the output noise, connect one end of a BNC
connector J1. Connect the other end of the BNC cable
to an oscilloscope with a 50Ω input impedance. Refer
to Application Note 70 for more precise techniques for
measuring the output noise.
