3 Specifications and Characteristics
32 U2000 Series Operating and Service Guide
Introduction
The U2000 Series USB power sensors are average, wide dynamic range power
sensors that can be used with a PC or any selected USB- based Agilent
instrument.
The specifications contained in this chapter are valid ONLY after proper
calibration of the power sensor and apply to continuous wave (CW) signals
unless otherwise stated. The recommended calibration interval for this
product is 1 year. Specifications apply over a temperature range 0 °C to +55 °C
unless otherwise stated.
Specifications quoted over a temperature range of 25 °C ±10 °C apply to a
relative humidity of 15% to 75% and conform to the standard environmental
test conditions. These specifications are valid after a 30- minute warm- up
period.
The dynamic range of the U2000 Series USB power sensors is –60 dBm to +44
dBm and the range is divided into two independent measurement paths — a
high and a low power path, as shown below:
Some specifications are detailed for individual measurement paths, with the
automatic switching point at:
• –10 dBm for U2000/1/2/4A
• 0 dBm for the U2000/1/2H
• +20 dBm for U2000/1B
Supplemental characteristics, which are shown in italics, are intended to
provide useful information with regard to applying the power sensors in that
they contain typical, but non- warranted performance parameters. These
characteristics are shown in italics or denoted as “typical”, “nominal” or
“approximate”.
