Specifications

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 one year. Specifica-

tions apply over a temperature range

0 to +55 °C unless otherwise stated.

Specifications quoted over a tem-

perature range of 25 °C ± 10 °C apply

to a relative humidity of 15% to 75%

and conform to the standard environ-

mental test conditions. Specifications

are valid after a 30-minute warm-up

period.

Supplemental characteristics, shown

in italics, are intended to provide

useful information with regard to ap-

plying 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”.

Measurement speed

Normal: 20 readings/s

x2: 40 readings/s

Fast: 110 readings/s

Buffered (50 readings):

1000 readings/s1

The U2000 Series USB sensors have

two measurement modes:

Average only mode (default mode):

optimized for wide dynamic range.

In this measurement mode, a trigger

can be controlled externally via TTL

input.

Normal2 mode: used for making aver-

age power measurement in a defined

time interval (time-gated measure-

ment) with reduced dynamic range.

A trigger can be derived from an RF

signal (internal trigger) or controlled

externally via TTL input (external

trigger).

1. The 1000 reading/s is the derived measurement speed from the first 50 readings in buff-

ered mode. The maximum number of measurements that can be obtained in one second is

250 readings in buffered mode.

2. Not applicable for U2004A.
