3) Frequency reference
Frequency accuracy: ± (time elapsed since the last calibration date × aging rate + temperature
sta calibration accuracy)
Aging rate: ± 1×10
-7
/year
Temperature stability: ± 1.5×10
-8
(20°C ~ 30°C), ± 5×10
-8
(full temperature range)
To obtain the initial calibration
accuracy: ± 4×10
-8
Note: The default time elapsed since the last calibration date is one year.
4) Residual frequency modulation
≤ 0.25 Hz × N (10 Hz refers to the resolution bandwidth and the video bandwidth respectively, the nominal
value within 20ms,and specific value of N depends on harmonic times of frequency band division)
5) Frequency readout accuracy:
± (frequency reading × frequency reference ac 0.10% × frequency span + 5% × resolution bandwidth
+ 2 Hz + 0.5 × horizontal resolution *)
* Horizontal resolution=frequency span/ (points of sweep-1), the default points of sweep of 4051 is 1001.
6) Marker frequency count
Accuracy: ± (maker frequency × frequency reference ac 0.100 Hz)
Counter resolution: 0.001Hz
7) Frequency span
Range: 0 Hz, 10 Hz ~ the maximum frequency range of the instrument
