The Bird Model APM-16 RF wattmeter is designed to
keep pace with the ever growing complexity of digitally-based
communication systems. Bird's Model 43 and most other wattcmeters
available today were designed to measure power of constant
amplitude, sinusoidal waveforms. Modern wireless communication
systems can use a variety of digital techniques to combine many
voice data channels into a complex, composite RF signal.
Measurement of such signals with a conventional wattmeter may yield
unacceptable errors. The APM-16 employs active circuitry to deliver
accuracy of ± 5% for multiple-access technologies such as CDMA,
TDMA, FDMA and other digitally-encoded communication systems.
The Bird APM-16 is an insertion wattmeter designed
to measure RF power and load match in 50 ohm transmission lines. It
has a maximum VSWR of 1.05 for frequencies up to 21 MHz. The
meter provides direct readings in watts with an expanded linear
scale for easy reading. The scale is graduated for 25, 50, and 100
full scale. Elements are available in a variety of power and
frequency ranges.
Features
- Designed especially for RF power measurement in PCS, cellular,
ESMR, paging and similar communication systems
- Equally effective for measuring RF power in conventional analog
systems
- Uses APM-series plug-in elements to cover a wide range of
frequency and power levels. Simple Thruline® style operation for
instant forward or reflected power readings
- Interchangeable QC connectors for fast hook-up
