Applications
Fault finding on PCBs with the 1207 Inductive Probe
The Willtek 1207 Inductive Probe is designed for the
repair of modern, highly integrated printed circuit boards such as
those found in today’s mobile phones. High level service centres need
to measure the LO frequencies emitted on transceiver components, but do
not have test pins available for this task. Most of the latest designs
no longer have any contact point for measuring the important
synthesizers. The probe helps to overcome this obstacle by measuring
the magnetic component of the field emitted by the device under test –
a faster, more efficient way for the service technician.
R&D engineers will use the 1207 to test printed
circuits, or to perform fast EMC measurements without having to lease
an expensive shield room.
Communication System Testing
The 9103 can measure channel power and spectrum of the
wide variety of communication systems transmitting between 100 kHz and
7.5 GHz. Applications covered by the 9103 Handheld Spectrum Analyzer
include cellular and cordless telephony, aviation signals, directional
radio, VSAT (very small aperture terminal) and signals in the 5 GHz
unlicensed band, such as Wireless LAN (WLAN) and WiMAX. RFID signals
are best analyzed in the zero-span mode provided by the spectrum
analyzer.
Reflection Measurements
The 9130 VSWR/DTF Reflection Measurement Option and the
9160 VSWR/DTF Bridge enable the acceptance and maintenance of
professional antenna systems, such as those used for cellular base
stations. Every customer operating a fixed or mobile radio with an
antenna system can now test the performance and match of his antenna
system over the desired frequency range in one view, using the new
reflection measurement mode. Designed for cable tests, the new DTF
measurement mode shows all relevant problems such as kinks, faulty
connectors or water ingress, which can arise along coaxial cables.
The reflection measurement mode, which is part of the
9130 VSWR/DTF Reflection Measurement Option, includes high-precision
vector calibration. So the 9103 supports you in measuring the return
loss at an accuracy that exceeds cellular phone operators’ requirements
today. Modern antenna systems for cellular networks are easily tested
with the 9130 VSWR/DTF Reflection Measurement Option and the 9160
VSWR/DTF Bridge, supporting the specified measurements with superior
performance over the frequency range up to 4 GhZ.
With its measurement precision and speed as well as its
easy handling, the 9103 with the VSWR/DTF options helps to speed up
usual antenna tests and to minimise the risk of wrong operation by
workers on site. Measurement results stored in the instrument can then
be included in your acceptance documentation, thanks to the 9100 Data
Exchange Software.
RMS Detector Testing
The 9132 RMS Detector fills the 9103’s channel power
measurement mode with precision. Broadband signals can be measured more
precisely so that the detector is helpful in measuring all kinds of
signals that are similar to noise in their spectral structure, such as
WCDMA, DVB or WLAN signals. Such signals are smoothed and displayed
with the precise RMS level.
Radiation Measurements
The
9103 with the 9131 EMF Measurement Option allows network operators and
installers of broadcast transmitters to easily measure the
electromagnetic field (EMF) caused by the radio frequency emission from
the antenna. Appropriate antennas for different purposes are also on
offer and optimised for use with the 9103:
- 9170 Biconical Antenna (for radiation immission measurements)
- 9171 Isotropic Antenna (for radiation immission measurements)
- 9172 Directional Antenna, 80 – 1000 MHz
- 9173 Directional Antenna, 300 – 3000 MHz
Regulatory
bodies and engineering offices can also check the immission of
electromagnetic radiation in the range from 100 kHz to 4 GHz, without
the need for an external PC. At the price of an instrument that only
performs radiation measurements, the 9103 also supports various other
applications in the areas of spectrum and network analysis.
Where
necessary, the 9103 can be controlled from a remote station via serial
interface or even TCP/IP. This makes it the ideal choice for cyclic
measurements over a modem or the Internet.
