Specifications
Specification Supplemental information
Frequency
Frequency range 1 MHz to 20 GHz (usable to 9 kHz) AC coupled
Internal 10 MHz frequency reference accuracy
Aging rate ± 1 ppm/year
Temperature stability ± 1 ppm Referenced to frequency reading at 25 °C.
Temperature varied at max. of 2 °C per
minute. Control voltage held at voltage
control range midpoint
Frequency readout accuracy with marker (start, stop, center, marker)
Marker resolution (frequency span)/(sweep points - 1)
Uncertainty ± (frequency indication × frequency
reference uncertainty + 1% × span + 20%
× resolution bandwidth + marker resolution
+ 1 Hz)
Frequency reference uncertainty = (aging
rate × period of time since adjustment +
temperature stability)
Marker frequency counter
Resolution 1 Hz
Accuracy ± (marker frequency × frequency reference
uncertainty + counter resolution)
RBW/span ≥ 0.02; marker level to displayed
noise level > 25 dB; frequency offset 0 Hz
Frequency span
Range 0 Hz (zero span), 100 Hz to 20 GHz
Resolution 1 Hz
Accuracy ± (0.22% × span + span/(sweep
points - 1))
