1-15. Leveled Sine Wave Specifications ( ≤ 600 MHz)
Note
The GHz Option offers an extended 600 MHz to 2.1 GHz Leveled Sine
Wave range. If the GHz Option is installed, see the Leveled Sine Wave
Specifications (> 600 MHz) table in Chapter 8 of the 5820A Operators
Manual.

[2] As an example, a 5s [0.2 Hz] marker would have an uncertainty of: 0.2 Hz * 2.5 ppm + 5 µHz = 5.5 µHz. The valid values are
0.2000055 to 0.1999945 Hz or 4.9998625 s to 5.0001375 s.
