Frequency reference
Accuracy ±[(time since last adjustment x aging rate) + temperature stability + calibration accuracy]
Aging rate ± 1 x 10 –7 / year
Temperature stability 20 °C to 30 °C ±1 x 10 –8 0 °C to 55 °C ±5 x 10 –8
Achievable initial calibration accuracy ±7 x 10 –8
Example frequency reference accuracy
1 year after last adjustment = ±(1 x 1 x 10 –7 + 1 x 10 –8 + 7 x 10 –8 )
= ±1.8 x 10 –7
Frequency readout accuracy (start, stop, center, marker)
± (marker frequency x frequency reference accuracy + 0.25% x span + 5% x RBW + 2 Hz + 0.5 x horizontal resolution*)
* Horizontal resolution is span/(sweep points – 1)
Marker frequency counter
Accuracy ±(marker frequency x frequency reference accuracy + 0.100 Hz)
Delta counter accuracy ±(delta frequency x frequency reference accuracy + 0.141 Hz)
Counter resolution 0.001 Hz
Frequency span (FFT and swept mode)
Range 0 Hz (zero span), 10 Hz to maximum frequency of model
Resolution 2 Hz
Accuracy ±[0.2% x span + span / (sweep points – 1)]
