U2000 Series USB Power Sensor Specifications

The U2000 Series USB power sensors are true average, wide-dynamic-range RF/microwave

power sensors, based on a dual-sensor diode pair/attenuator/diode pair topology.

The U2000 Series USB power sensors can be operated on N1913A/14A via the USB host

port (options).

Specifications valid with the following conditions:

– After zeroing

– Number of averages = 1024

– After 30 minutes of power-on warm-up

1. This accuracy is essentially a combination of linearity, instrumentation accuracy, and traceability to

absolute accuracy at 50 MHz, 0 dBm.

Note: Mismatch uncertainty, calibration factor uncertainty, and power level dependent terms

(zero set, drift, and noise) are excluded in this specification.
