There are 2 period generation sources available:
• startable oscillator (variable frequency oscillator VFO)
• high-accuracy frequency generator (PLL)
Glitch-free timing changes
You can sweep your timing values without danger of spurious pulses or
drop outs that could cause measurement errors. This applies to
continuous mode with timing values < 100 ms (frequency: < 10 Hz), and
consecutive values between one-half and twice the previous value.
