Jitter with no averaging 5 dB Y-factor standard deviation <0.15 dB
1. Characteristic values are met or improved on by 90% of instruments with 90% confidence.
2. Subject to maximum operating input power
3. Specified for a 4 MHz measurement bandwidth. Jitter in noise figure is equivalent to jitter in
Y-factor to within 10% for ENR >14dB and F <4dB. At minimum smoothing, jitter can limit
accuracy; the small jitter at high smoothing does not.
4. For true Gaussian noise, jitter reduces with increased averaging, typically by a factor of
