Keysight N1914A - U2000 Series Power Sensors Specification

Specifications and Characteristics 1
Keysight N1913/1914A Service Guide 33
[a] Within one hour after zero set, at a constant temperature after a 24-hour warm-up of the power meter.
[b] The number of averages at 16 (for normal mode) and 32 (for x2 mode), at a constant temperature, measured over a
one minute interval and two standard deviations. For Keysight E-Series power sensors, the measurement noise is
measured within the low range. Refer to the relevant power sensor manual for further information.
[c] Specification applies to the low power path, up to 75% relative humidity.
[d] The zero drift and measurement noise specifications are tested at 50 MHz.
