[1] The DC offset plus the wave signal must not exceed 30 V rms.
[2] Applies to the 10 % to 90 % of the triangle waveform 500 mV p-p to 10 V p-p.
[3] No specification below 10 Hz or above 10 kHz.
[4] With 10 MHz external reference selected, the uncertainty becomes that of the external clock plus 5 µHz.
[5] Uncertainties below 10 Hz are typical.
[6] Square wave rise/fall time typically less than 500 ns.
