8 Characteristics and Specifications
DC Power Supply Specifications
254 U3606A User’s and Service Guide
[3] Specification applies when the positive or negative pulse width is greater than 50 μs.
[4] For frequency signals greater than 100 Hz, an additional 0.1% per 100 Hz is added. The accuracy of the pulse width should
be calculated as:
Calculation example: Frequency setting = 4800 Hz, Duty cycle setting = 50%
The pulse width accuracy (for frequency setting 4800 Hz and duty cycle setting 50%) is calculated as 0.2083 ms ±10.625 μs.
