Timing
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.
Period
Period can also be entered as frequency.

There are 2 period generation sources available:
• startable oscillator (variable frequency oscillator VFO) with fixed latency
from trigger input to outputs.
• high-accuracy frequency generator (PLL) .
