USB Power Meter

MODEL 81041

The model 81041 is a portable, self-contained
RF Wattmeter that features a
studio-quality analog meter and USB
interface. Numeric, analog meter, and bar
graph data are simultaneously displayed
on a PC’s monitor. The functions
indicated are Forward and Reflected
Power, both in Watts and dBm, plus an
automatic calculation of SWR and Return

The internal dual socket line section and
forward / reflected switch gives the user
the ability to display either forward or
reflected on the analog meter, while both
are displayed simultaneously on the PC.

Our use of a rugged shock mounted
meter with a mirror-backed scale along
with superior taut band technology,
provides reliable and accurate readings
of either forward or reflected power on
the meter.

The 81041 uses standard elements to
detect average RF power from 100 mW to 10 kW and from 2 MHz to 2.3 GHz. Software and a detachable six foot USB cable are included for a simple installation on any PC using Windows ® Vista, 2000, XP or NT. No additional cables, AC or DC power adapters, batteries or custom remote sensors are required.

Type N female connectors are standard
with over 20 interchangeable QM
connectors available such as 7/16, SMA,
UHF, BNC and TNC types in male and
female genders.
