Timing Specifications
Period 
Period can also be entered as frequency. 
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.
Period
Agilent 81101A
Range: 20 ns to 999.5 s
Resolution: 3.5 digits, 5 ps best case for VFO
4 digits, 1 ps best case for PLL
Accuracy:  PLL: ±0.01%
VFO: ±5% 
Repeatability: typically 4 times better than accuracy
RMS-jitter: PLL: 0.001% + 15 ps
VFO: 0.01% + 15 ps
Frequency range: 1.00 mHz to 50 MHz
